      "body": "Abstract:\n\nThis article will be discussing how a person can generate a passive income from their cryptocurrency using CeFi platforms (centralized finance). It will focus on compounding cryptocurrency payments, which platforms are available for users as well risks involved. \n\n\n![image.png](https://cdn.steemitimages.com/DQmbpybSfJKQ93GHpYk29YStAFpXSoex3BDdrJxiJNPjSZL/image.png)\n\n\nDisclaimer:\n \nThis article should not be interpreted as investment advice. If a person wishes to invest their funds into cryptocurrencies or use a CeFi platform, then they do so at their own financial risk. It is expected that a person seeks investment advice from a qualified financial advisor first before investing in cryptocurrencies and has a good understanding of the security risks involved.  \n\n![image.png](https://cdn.steemitimages.com/DQmS9qrHgWSNRcXK2tSmiadeLmNNMVhd4mSfNCGjFNdmedT/image.png)\n\n\n\nIntroduction:\n\nAt the time of writing the Reserve Bank of Australia (RBA) has opted to leave the nation’s official interest rate at just 0.1 per cent. This has been kept at a historic low with the intent of enticing Australians to borrow more money from banks in the form of mortgages. This is one of the factors why Australian house prices particularly in the metropolitan areas continue to rise in price and are now some of the most expensive in the world. \n\n\n![image.png](https://cdn.steemitimages.com/DQmZfAagifxG184nXVnQES3HzvSiqcfm3bn7CrxmuMZ4q6c/image.png)\n\n\nOn the other hand, low-interest rates give Australians little advantage if they are savers as it just serves to reward those taking out further loans. The Australian Bureau of Statistics states that there are currently 3.9 million Australian retirees, while most of these retirees are relying on their Superannuation for their daily living needs many of them also have funds within their savings accounts which are now generating next to no passive income. \n\nYounger Australians are now put at an incredible disadvantage, faced with increasing house prices, increasing rental properties and historically low-interest rates for their saving accounts it is near impossible for our younger generation to get ahead and form any wealth for their futures.  \n\nMost major banks within Australia will only offer a customer around 0.30 % p.a. for a savings account. Since these interest rates are so low it would make sense for a person to shop around for a better deal to grow their wealth faster or completely exit the old traditional banking system altogether. \n\n\n![image.png](https://cdn.steemitimages.com/DQmXyZ3noQuUcLNTXCSrZQcMUJr92WnBnj1Uo21f9NeFjgn/image.png)\n\n\nCryptocurrency:\n \nCryptocurrencies give a person many advantages over the traditional banking system. \n•\tIt is a decentralized currency, no owner, no bank, or government has any control over it. It is valued by the global market.\n•\tIt can be sent anywhere in the world within minutes in a true peer to peer method, with no 3rd party needed to oversee the transaction.\n•\tIt gives the person the ability to be their own bank (non- custodial) and have control over their wealth. \n•\tSome cryptocurrencies are capped at a limited supply. In theory, the value of these capped cryptocurrencies should go up over time outpacing the rate of inflation for fiat currencies. \n•\tCryptocurrencies such as USDT and USDC are pegged to the USD one to one. (A stable coin). This giving the person the option to sell out their cryptocurrencies into a stable coin and wait to re-enter the market.\n•\tBlockchains are very difficult to hack (but not impossible). It is a fact that Bitcoin’s Blockchain has never been hack to this present day.   \n\n![image.png](https://cdn.steemitimages.com/DQmXB7zBRnQUBL6L4yo3uW91Eg8HXri4EmRm43rsFxCuArF/image.png)\n\n\n\nCompounding Cryptocurrency using CeFi:\n\nIt is expected that the reader already knows how to buy and sell cryptocurrencies from a given exchange. Investing in cryptocurrencies does carry with it some financial risk however long-term data taken from the top 2 cryptocurrencies biggest by cap market value (BTC and ETH) states that their value has increased exponentially over time and has far outpaced the inflation rate of fiat currencies.   \n\nA cryptocurrency holder can choose the safest option by leaving their holdings in their chosen digital wallet and wait overtime for its value to increase. Or they can choose to add risk by making their cryptocurrency work for them by compounding it using a high-interest saving account (A crypto bank). This is possible by using a 3rd parties centralized finance platform (CeFi). At the time of writing the top 4 most popular CeFi platforms that offer this service were:\n\n\t\n\t\t\tCryptocurrency:\tInterest Rate P.A\n\nBlockFi\t\t(New York City) BTC 5% ETH 4.5%\n\nCelsius\t\t(New York City) BTC 5% ETH 5.0%\n\nNexo \t\t(Switzerland)\tBTC 6.0% ETH 6.0%\n\nCrypto.com\t(Hong Kong) BTC 6.5% ETH 5.5%\n\nANZ Savings\t(Australia) \t\t\tAUD\t\t\t0.30%\n\nNAB Savings\t(Australia)\t\t\tAUD\t\t\t0.30%\n\nReviewing the interest rate column to the right it is clear that CeFi platforms offer a much better interest rate than any traditional banking system for their savers. If BTC and ETH continue to grow in value over time, then a person’s wealth would very quickly outpace any passive income that they generate from a traditional savings account simply by \ncompounding the rewards.  \n\n\n![image.png](https://cdn.steemitimages.com/DQmcGQUMEPbvDKDoRLmFchFddLCYHmMSJH9YkEyBzocYxo5/image.png)\n\n\nSecurity Risks and Disadvantages with CeFi:\n\nWhenever a 3rd party is involved there now includes an element of risk. The old saying in the Crypto industry still stands “not your keys, not your crypto”. When a person has chosen to hold their cryptocurrency with 3rd parties, they have given up ownership of their private key, technically speaking they are now no longer the owner of their cryptocurrency, which goes against the libertarian ideal of cryptocurrencies being decentralized.\n\nCybercriminals are now all too aware that CeFI platform represents a treasure chest of cryptocurrency wealth. This making them a prime target to be hacked and their employees to be corrupted or blackmailed into giving up security secrets. \n\nIn a worst-case scenario, one of these CeFi platforms could fall victim to a hack attack whereby their customers lose all of their funds and it must be noted that this has indeed happened to centralized exchanges in the past.   \nCeFi platforms are also well aware that they are targets too, and so have implemented the best cybersecurity personnel to work with them to keep their platforms safe and secure. Some of these platforms now offer insurance as an added layer of safety to their customers should the worst event occur. For added confidence, these top 4 CeFi platforms are based in countries governed by strict financial regulations so the chances of fraud or corruption can be limited. A person should be extremely cautious if one of these platforms is based in a country that is not known to have a respected financial regulator (The financial regulator for Australia is ASIC). A person is very much encouraged to have a strong password and implicate 2FA on all their CeFi wallets as they too have a responsibility to ensure that their funds are kept safe and should keep up to date with the latest “phishing” email scams.  \n\n![image.png](https://cdn.steemitimages.com/DQmYZ9Q7pSQzHHJwUiazGJXMVHi37PxtnDdSvnhJQATC1zj/image.png)\n\n\n\nPromotions:\n\nFrom time to time these CeFi platforms will be offering promotional incentives for new users to hold their cryptocurrencies on their platforms, all a person has to do is comply to the terms and conditions set out and they can collect their rewards. There is also the added bonuses for referring the platform to bring other new users to sign up. \n\nDiscussion:\n\nInterest rates around the world are at historic lows and in some countries, they are at negative rates. The RBA has not ruled out that negative rates could be implemented in Australia to stimulate further spending. Low interest rates do not favour people who want to save their money, and over time their money loses its purchasing power through inflation. A saver is effectively forced to spend their money or take out a loan to buy an asset (A house). CeFi platforms give people a new opportunity to grow their cryptocurrency portfolio. It would be extremely foolish for a person to invest 100% of their portfolio on a CeFi platform due to the risk of hacking attacks. But it is encouraged for a person to find out what level of risk they are comfortable with taking and invest a certain percentage of their portfolio to generate some passive income. It is still unclear whether these passive incomes are subjective to a capital gains tax (CGT) and depending on where a person lives it is up to them to find out what their local tax laws are. CeFi platforms will provide their customers with customer support services to manage their needs.   \n\n\n![image.png](https://cdn.steemitimages.com/DQmS82X1MfNsJLpuFnqz7YHNqGQkNgcewfnk5XviLgESigX/image.png)\n\n\nConclusion:\n\nUsing CeFi platforms is an excellent way for a person to grow their cryptocurrency wealth over time. It is not the same as trading where a person must watch the market 24/7 and the more a person refers other people to the platform the more incentives both people can make. Cryptocurrency holders are encouraged to shop around and keep up to date with the latest CeFi platforms and the variable rates that they offer, they should also beware of the never-ending phishing emails that a user is expected to receive.  \n\nRobert Lavington\n6/6/2021",

The potential impact NFTs could have on the video gaming industry, and the use cases NFT’s could give to the average person.\n\nIntroduction:\n\nThe acronym NFT stands for “Non-Fungible Token” and it is quickly gaining attention throughout the cryptocurrency industry. To begin with, it is first necessary for the reader to understand the word “Fungible”. \n\nFungible Asset:\n\nThe word \"Fungible\" has the same terminology like the word \"Asset\", this can be a real-world asset such as a car, a house or a digital asset such as a cryptocurrency. \n\n\n![image.png](https://cdn.steemitimages.com/DQmVbgZoCkSKkJ2sLWw8atnpqmqDo5bHxa31H38cr3QpgRJ/image.png)\n\n\nWhen items are fungible it means they are interchangeable with other items of equal value, however, they are not identical. For example, if two people swapped $10 notes with each other then they would have both swapped the notes for exactly the same amount of value. However, the two $10 notes that were just swapped would not be exactly the same. Meaning that they would not have the same security codes written on their backs and they would have different identification watermarks. So the $10 notes are both “fungible” assets, in the sense that they are interchangeable for the same value or fungible with each other. \n\nNon-fungible Asset:\n\nA “Non-fungible” asset is the complete opposite of a “fungible” asset. It is something that is unique and rare, is not divisible into smaller denominations, and it is not interchangeable with anything else because it has its own unique value.\n\n\n![image.png](https://cdn.steemitimages.com/DQmPeqbTu6Mxxp5VeuGiHE2DUZy5XUX5QAPLsEGwMm9HceH/image.png)\n\n\nAn example of a real-world non-fungible asset would be the Mona Lisa painting currently held within the Louvre museum in Paris. This was designed and painted by the one and only artist “Leonardo Da Vinci”, it is a masterpiece of artwork giving it a priceless value and its own uniqueness. It could never be swapped or interchanged with another painting of its kind because there is only ever going to be one Mona Lisa painting. It is true that copies could be made of the Mona Lisa such as a photograph, but those copies would never hold the same priceless value of the true original painting, it is, therefore, a Non-fungible asset.\n\nDigital NFT’s in the cryptocurrency world:  \n\nWithin the cryptocurrency industry digital NFT’s can be:   \n \n•    Collectible cards\t\t\t\n•    Virtual real estate\n•    Digital Photographs \n•    Digital Images\n•    Digital Videos\n•    Digital characters\n•    Digital artwork\n•    Digital Music \n\nNFTs utilise blockchain technology to record ownership and validate their authenticity just like cryptocurrencies do such as ETH and BTC. Whenever a Bitcoin is sent from one wallet to another there will always be transactional data written to the Blockchain. Unlike cryptocurrencies each NFT is unique, it would therefore be better to think of an NFT as a digital collectible item or a cryptocurrency as a picture.\n\n\n![image.png](https://cdn.steemitimages.com/DQmaGvDDXQUQHEFEtYSTgV4JnsB89T1SCQGCmLuFZ6pQypH/image.png)\n\n\nOne of the first examples of an NFT was called “Crypto kitties” released in 2017 it was a game that featured pictures of cartoon cats whereby people were able to buy, sell and breed the cats with other cats to make new cats. The game was such a success that it caused major congestion problems on the Ethereum blockchain in which it was running on and the highest amount paid by a person for one of these Cryptokittens was $170k USD in 2018.\n\n\n![image.png](https://cdn.steemitimages.com/DQmTBMccwKpkTSE11t6urzJdHRPhwxYoBJzH3c6PkU43929/image.png)\n\n\nCopying NFT’s:\n\nA commonly asked question regarding NFT’s is can they be copied? And why spend any money buying an NFT when it can just be copied. The answer is yes, with a simple right-click of a mouse button or a screenshot the digital picture (NFT) can be copied/downloaded and stored as a JPEG file. However, in doing this we immediately run into the same problem as trying to copy the Mona Lisa painting. Buyers and collectors would instantly know that this is just a copy from an original NFT because there would be no evidence of the transactional data occurring on the blockchain. \nOnce a person has ownership of an NFT no other persons can withdraw that NFT from them because they are the owner of the private key (the digital receipt). Much the same way a person owns a bitcoin no one can take the bitcoin from that person because they are the owner of the private key.\n\n\n![image.png](https://cdn.steemitimages.com/DQmTBhKZA3Mayuo1Z3EcE2xaVZRugMEdz2RKhYTzon3amH5/image.png)\n\n\nDigital NFT’s in the gaming world: \n\nAt the end of 2020, the video gaming industry was worth an estimated $90 billion USD with one of the most popular online games being Fortnite. This figure is set to grow well into a $100 billion USD industry with continued advancements in technology such as faster internet infrastructure and virtual reality. \nOnce a gamer has progressed to a new level within their game or they are able to complete the game they are often rewarded with a digital item such as a sword, a shield, a certificate, their name on the hall of fame, etc. \nCurrently, these digital rewards are always kept within the game itself, the gamer is unable to take their rewards out of the game and store them in their own personal digital wallet of achievements and they are unable to take the rewards out of the game and into other unrelated games as the two are not compatible. \n\n![image.png](https://cdn.steemitimages.com/DQmat4ao44odRzfYWPF736FJ2LSDW3yMmmrTx21efmdwBK7/image.png)\n\n\n\nNFT’s in the gaming industry is set to change all of this. In the not too distant future gamers will have the ability to remove their digital rewards such as a sword and place those rewards into their own personal wallet. This new method will give the gamer sole ownership of the digital item (NFT) and not be at the mercy control of the games developers should there ever want to implement new rules or if the game crashes so that the gamer lost all of their rewards and their given time. \n\n\n![image.png](https://cdn.steemitimages.com/DQmbMWUrb17JncFX7rXgwpNhSWSSyfqPihHsJqt7AsfpzKi/image.png)\n\n\nSelling and buying NFTs:\n\nAt the time of writing the biggest online exchange where a person is able to buy and sell their NFTs is called “Opensea”. Currently, only digital artwork can be traded on this exchange, however NFT’s within gaming is coming where the gamer would be able to go to the exchange and sell their digital rewards to other gamers.  \n\n\nDiscussion:\n\nNFT’s are still a new concept and there is still much confusion among the general population as to exactly what they are. As with all blockchain technology it is constantly evolving and changing over time with much more room within the industry to grow and improve. Cryptocurrencies are simply digital transactions represented on a screen as numbers. Whereas NFT’s can be in the form of a visual picture, to some people this picture may hold increased value because the NFT represents a picture of something that the person admires and wants to keep. From a psychological point of view, a person can become personally or emotionally attached to a picture, thus making them want to keep the picture over a period of time or unwillingly needing to sell their picture (NFT) for a high asking price. This year (2021) Jack Dorsey the CEO of Twitter was able to sell the first-ever “Tweet” from 21st of March, 2006 for an estimated $2.9 million this proving that there is still huge potential for money to be generated within the industry and concluding that anything digital can become an NFT. \n\n\n![image.png](https://cdn.steemitimages.com/DQmS82X1MfNsJLpuFnqz7YHNqGQkNgcewfnk5XviLgESigX/image.png)\n\n\nConclusion:\n\nThe gaming industry appears to have much to gain from the introduction of NFT’s, also the owner of a websites URL could become extremely lucrative. However the NFT market is given its value by speculation, all NFTs are only valued by whatever a person is prepared to pay for it. With this in mind from an investment point of view, it would make sense to buy an NFT that represents a very rare moment in history or invest in the next digital Crypto kitties craze. \n\nRobert Lavington\n02/06/2021",

Centralized means that the sector is controlled by a central authority overseeing the operation of the business. Although these services have been available to the public for many decades (within western countries), they possess many inefficiencies and disadvantages. One of the most memorable events which brought the whole centralized financial service into question was the global financial crisis (GFC) between the periods of 2007 and 2009. From research gathered, there appears to be no one primary cause of the GFC. Although it is widely accepted that the deregulation of the financial industry (which allowed banks mostly based in America to lend out funds to be used to buy real estate) was then used as a hedge fund to continue their profit growth. It was this lack of transparency within the centralized financial services whereby the financial governing bodies were then not made aware that property was being used as a hedge fund leading further to a real estate crash.   \n\nOther disadvantages of a centralized financial service can be described as:\n\n•\tAlways the requirement for a third party to oversee any transaction of assets between two parties resulting in service fees being paid by the two parties. \n•\tPlagued with regulations that exclude many people from the financial system due to its stringent requirements e.g., you have to be an Australian citizen to hold an Australian bank account.  \n•\tIs at risk of fraud or mismanagement of funds from lack of transparency. \n•\tA third party holds sensitive information about their customers which can be exposed.\n•\tA custodian third party (a bank) is trusted with safeguarding their customer's financial assets.\n•\tExtended time to process customers transaction due to a third party having to examine all of the necessary terms and conditions within a contract. \n\n\n![image.png](https://cdn.steemitimages.com/DQmRocczweXV3LqBterUYNyxyW68R3zkpGB6Ju8NfMJ1nRb/image.png)\n\n\nConventional Financial Contracts:\n\nConventional financial contracts are used to ensure that both Party A and Party B meet their terms and conditions within the contract before the final execution of that contract. The disadvantage of this however is that there is always the need to incorporate a trusted third party entity which then oversees and ensures that the terms and conditions are met by both parties. \n\n\n![image.png](https://cdn.steemitimages.com/DQmYqh5zdaEvFtmLVejschwheqbhZ4k8AT7XEnT6KKbNzem/image.png)\n\n\nTrusted Third party Entities:\n\nA conventional financial contract is always used when a large expensive asset such as real estate is to be brought or sold. The two parties are going to have to utilise the services of a third party such as an estate agent and a lawyer. It is the job of these third parties to oversee that the process complies with the local law and that the transaction takes place from Party A to Party B. Currently, without the use of these third-party services a peer-to-peer transaction would immediately run into problems. One of those problems would be an issue of trust between Party A and Party B. Once the transaction has been executed, the third parties take their commission fee. This can be as high as 6% of the sale price of the asset which would then be passed on to Party A and Party B.\n\nDecentralized Finance:\n\nThe acronym “DeFi” stands for “Decentralized Finance”. It came into existence in 2018 and its explanation is within the name itself. It is simply any form of financial service or a financial sector that provides a service to its customers in a decentralized way. This means that there is no one central entity or central authority controlling the financial service that is being offered and there is no need for any third-party service within the process. \n\nDeFi is only made possible by utilising Blockchain technology. Because a Blockchain is a decentralised network allowing for the storage of digital data that cannot be deleted or modified, it allows this data to be viewed on an open-source platform. The advantage is that this transaction can be openly viewed between two parties, thus allowing a peer-to-peer method of transfer to take place. There is now no need for any third parties to be involved to oversee the transaction. \n\nThis is only possible because a DeFi service is used by customers in the form of a computer protocol or program using a blockchain as its underlying platform. Much the same way as Microsoft Windows is the operating system for a desktop personal computer (PC). Other software programs can be built and run on top of the existing operating system such as Microsoft Word or Microsoft Excel. The Android operating system for a smartphone (owned by Google) would be another example whereby third-party developers can build and run their applications on top of the Android operating system.\n\nThese comparisons can be used to describe a DeFi program explained again, it is simply a computer protocol or program operating on top of a blockchain platform that services its customer's financial needs. More specifically, a DeFi protocol can also be termed as a “smart contract”.\n\nBefore reviewing what exactly is a smart contract it must be noted that there are currently many different types of Blockchains available and still in development. Each of these Blockchains is being designed so that they can work and integrate within a given industry as each industry functions in its own unique manner. For example, there is now Blockchains in development to serve:\n\n•\tThe logistics and distribution industry;\n•\tThe video streaming industry; and \n•\tThe gaming industry.\n\nIt must also be noted that earlier blockchains are incapable of running smart contracts as they are now too basic and were never designed to run smart contracts. Think of this in terms of trying to run a high-performance video game on a PC built in the early 90s.\n\n\n![image.png](https://cdn.steemitimages.com/DQmaKGMR7UDKpVsZRrjNyELxMcbPjZ6NqDEjX2Ft7CSH1Lm/image.png)\n\n\nSmart Contracts: \n\nA smart contract is a digital automated agreement or terms and conditions that only execute when certain agreements within the contract have been met. Their main advantages and purposes are to:\n•\tRemove the typical third party seen within conventional contracts so that the smart contract can be executed in a peer-to-peer fashion between Party A and Party B; and \n•\tTo execute the transaction by minimizing the amount of trust required between Party A and Party B. \n\n\n![image.png](https://cdn.steemitimages.com/DQmXETGLrx4Y4nAqrSCwH2ik8M6V9mpnpEgk1857u2zSiDM/image.png)\n\n\nThe Vending Machine:\n\nA popular real-world comparison used is the vending machine example. This is whereby a customer inserts their funds into the machine with the intent of purchasing a soda drink, then the corresponding buttons are pressed and the selection of drink is made. The mechanical lever within the machine is activated and the soda drink is dispensed. The take-home point is that the transaction occurred without the need for third-party intervention, no cashier, clerk or governing body was needed and the transaction was peer to peer.\n\nWhen in operation, the vending machine is following a set of rules (or algorithms) which it does not deviate away from. It is told (or programmed) to only dispensed the soda drink when the correct amount of funds has been inserted and only once these terms and conditions have been met then the drink can be dispensed (contract fully executed).  \nA vending machine can be seen as a physical device that executes a smart contract in the real world. By digitalizing this concept and running it on top of a Blockchain, a smart contract can offer many new advantages to the customer. \n\nAdvantaged of Defi:\n\nThe world bank estimates that 1.7 billion people are currently unbanked and have no access to financial services. DeFi services give the potential to open up the rest of the world to new financial services irrespective of their income, race, wealth, culture or geographic location. A new user only requires internet access. Because smart contracts allow for the use of peer-to-peer methods of transfer, they can save both parties funds by not having to pay for third party services. The result is that these transactions are drastically faster than traditional methods. Now the sale of real estate that usually could take months to finalise can potentially just take a few days. This would in turn potentially speed up the process it takes to unlock this financial capital which for many people is their largest asset. The trust issues between the two parties are now minimized but unfortunately not completely eliminated just yet. It can however be seen that:\n\n•\tDigital peer to peer transactions is now a reality; \n•\tTransactions are cheaper because the third party is no longer taking a commission fee from the transaction;\n•\tFaster transactions occur because no third party is required to oversee and sign off on the transaction; and\n•\tBecause the smart contract is digital, it opens up new business opportunities to the world.\n\nDisadvantages of DeFi: \n\nBecause DeFi is still such a new and emerging industry, many problems have already been reported such as: \n•\tA Blockchain being unstable would have a knock-on effect on the operating smart contract.  \n•\tScalability is a Blockchains ability to process transactions. If there is too much data traffic on the Blockchain then this will cause a slow down in transaction speeds.    \n•\tThe coding within a Smart Contract must be written without any errors or bugs what so ever. If a Smart Contract is in operation containing errors it could lead to the complete loss of funds.  \n•\tSmart Contracts are and can have poor user interfaces, therefore making them confusing to use for the customer. \n\nDiscussion:\n\nWhen evaluating the data gathered, the new DeFi industry can be seen as what Uber has done to the Taxi industry or what AirBNB has done to the hotel industry. It is a new transition away from the traditional financial services and giving way to customers having more freedom and options. Smart Contracts should save both parties a lot of time and money by not having to utilise third party services. The DeFi industry could open up a whole world to new financial services as only an internet connection is required.  \n\n\n![image.png](https://cdn.steemitimages.com/DQmS82X1MfNsJLpuFnqz7YHNqGQkNgcewfnk5XviLgESigX/image.png)\n\n\nConclusion:\n\nDeFi is any form of financial service that services its customers in a decentralized way. A Smart Contract is simply a piece of code running on top of a blockchain that cannot be deleted or modified. It can be viewed by both parties simultaneously which brings trust and transparency to the transaction. It will only execute once certain terms and conditions within the contract have been met. No third parties are needed to oversee the Smart Contract as the coding within the contract already complies with local laws and terms and conditions are already set out. Conventional financial contracts will most likely still be used for many years to come until the general public gains much-needed knowledge and better user interfaces are developed that makes a smart contract much easier to use by the average person.",

The factors that differentiate these two algorithms and why are they used. The type of computer hardware that is needed for both POW and POS. Discussing Hash puzzles and the reasons why some blockchains are moving to the POS algorithm. \n\n\n![image.png](https://cdn.steemitimages.com/DQmaRFaU438TCHQtkfKGsUebPwD9BFr1LkQrH2kcYm6YhDo/image.png)\n\n\nIntroduction:\n\nPrevious blogs have discussed and explained what Blockchain technology is and the basics of how a Blockchain works. The main factors when understanding a Blockchain is that it is a decentralized data source that is open for anyone on the network to view (opensource). Whereby digital information can be written into a blockchain and once that information has been written it cannot be removed or modified due to the cascading domino effect that it would have on all of the other previous blocks. Once a block has been filled with data a new block must be added and chained to the previous old block to carry on the cycle. For a new block to be added to the chain there needs to be a consensus algorithm used, something that the whole community agrees on. That algorithm can either be POW or POS, although other algorithms are currently being investigated to further the use cases of Blockchain technology.  \n\n![image.png](https://cdn.steemitimages.com/DQmfPzeB8P4nHQrUSvEscsBNvtk5buubD2KV1XFuopZLPNf/image.png)\n\n\nWhat is a computer algorithm?\n\nAn algorithm can be described as a set of rules or sequences that a computer program reads and carries out to complete a given task. When a computer is reading an algorithm it could read as follows:\n\n•\tWhen “X” has been completed, “X” then goes on to complete “Y”.\n•\tThen when “Y” has been completed, “Y” go on to complete “W”. \n\n\n![image.png](https://cdn.steemitimages.com/DQmSgNCUGhA9GBpVv4qUY2GN88wWGLyKSB9ugnwkiG4m4Jx/image.png)\n\n\nProof of work: \n\nThe proof of work (POW) consensus algorithm was discussed within Satoshi Nakamoto’s white paper published in 2008 and was applied to the first-ever Blockchain. Although the first idea for POW algorithms was published in 1993 by Cynthia Dwork (A computer scientist from Harvard University) within her white paper it was only discussed as a potential tool to prevent fraud. Now the POS algorithm has been widely adopted by Blockchains for the purposes of mining cryptocurrency. \n\nWhen the POW algorithm is applied to a Blockchain it is the process of completing two actions using high-performance computer hardware. The first action is constantly validating and securing a blockchain network by working as a node. A node can be any computer that is tasked with validating the transactions that take place on a Blockchain. The second action is to solve complex computerised math problems known as “hash puzzles” with the intent of creating a new block to add to the chain.\n\nTo solve these hash puzzles a huge amount of computer processing power is needed. The type of computer hardware is given the name “a mining rig” and there are currently thousands of these mining rigs located around the world in operation today. \n\nMining rigs are run and operated by people who refer to themselves as “miners”. Their mining rigs are constantly analysing transactions that take place on a POW Blockchain and are competing with other mining rigs to be the first to create the next block to add to the chain. Once a block is full of transactional data and a new block needs to be added to carry on the process the mining rigs are then tasked with solving the computational hash puzzles. \nIt is when solving these hash puzzles where the huge amounts of computer processing power come into play as it is using brute force to go through every single possible combination to solve the hash puzzle the quickest, this type of approach is the “proof of work” algorithm because the mining rig has to show evidence that it has completed a form of “work” in solving the hash puzzle. As a reward for their “work”, the miners are given the native token (a cryptocurrency) associated with that particular blockchain that they are mining (a block reward) which holds real-world value. \n\nAdvantages of Proof of work: \n\nThe main advantage of the POW algorithm is that it makes a Blockchain very secure. Using POW means that it is extremely difficult (but not impossible) for an external hacker to take control of a Blockchain that is using a POW algorithm. The algorithm also prevents the “double-spend” problem whereby a person on the network could spend their holdings more than once as all of the nodes on the network would not allow the same transaction to pass by more than once.  \n\n\n![image.png](https://cdn.steemitimages.com/DQmPPh9FLa4suNYD4FWvEryA8fgDHkUQn55VVViEqmWraKE/image.png)\n\n\nDisadvantages of proof of work:\n\nDue to these mining rigs having to solve complex maths problems a significant amount of electricity is needed to operate the rigs 24/7. Environmental groups are now expressing their concerns about the large amounts of electricity POW algorithm are utilising. A study conducted by Cambridge University in 2020 found that POW algorithms account for 0.40% of the world’s total electricity consumption and that if this type of algorithm was a country then it would consume the total electricity supply of the Czech Republic or Colombia. \nSome Blockchains that still use POW algorithms also go through a process called the “halving process” every 4 years. This means that the block rewards given to the miners get halved in amounts thus increasing the need for more electricity and the need for yet even more high-performance computers to give them the faster hash rates (the speed at which a miner can complete the hash puzzle) to break even with profits. \nPeople who live in countries where the cost of electricity is high or is inaccessible are put at a clear disadvantage as it would not be profitable for them to run their own mining rig. \nThere is also the possibility of a 51% hack attack on a POW algorithm whereby a hacker takes control of more than 50% of the available nodes which has been responsible for disabling smaller Blockchains in the past and causing the native token associated with that Blockchain to plummet in value. \nAs more miners upgrade their hardware to compete with the next available block creation it also makes the POW algorithm less and less decentralized and more centralized to whoever has the mining rig with the fastest hash rates which starts to defeat the original purpose of a Blockchain being decentralized. \n\n\n![image.png](https://cdn.steemitimages.com/DQmUCEm6NeM3Rzwnh61sTfnZrfAnHhx1qQJMYAWhhMVGoc9/image.png)\n\n\nProof of stake:\n\nThe proof of stake (POS) algorithm was created in 2012 and is very different to that of the Proof of Work (POW) algorithm. POS was invented to address the current problems facing POW. Instead of having centralized mining rigs that create new blocks and add them to a chain POS works by using a random selection process by selecting the nodes already on the network to become a validator of the next block. This new algorithm means that there is now no need for expensive mining rigs to create and add new blocks. \n\nThis random selection process is based on a combination of factors such as:\n•\tThe number of native tokens already stored within the node.\n•\tThe age of the node and how long have the tokens been held within the node.\n\nAdvantages of Proof of stake:\n\nThe most notable advantage of POS is how much more energy-efficient it is when compared to POW as there is now no need for energy-demanding mining rigs. Using POS on a modern home computer that is on the network can act as a node that is validating the blockchain. Using this new algorithm makes this Blockchain much more decentralized as mining rigs are now no longer the only ones who can add a new block to the chain.\n\nDisadvantages of proof of stake:\n\nA POS algorithm appears to still favour the rich as one of its selection processes will be to block reward those who already have a lot of native tokens within their node.  \n\n\n![image.png](https://cdn.steemitimages.com/DQmPrhrj5ty7sgYwhT2Acf9ww9jjD926Zm7BquzcgjcRGC4/image.png)\n\n\nDiscussion:\n\nReviewing the current data there is overwhelming evidence that a POS algorithm is a much better option to use when protecting the environment due to the POW’s huge carbon footprint and realising that the energy consumption could be put to better uses. POW has created an arms race in computer processing power.  A POS algorithm promotes fairness to a blockchain so that the ordinary person does not have to invest huge amounts of funds buying and maintaining their own mining rig because anyone with a modern computer can start validating a blockchain and receive block rewards. POS promotes a more decentralized blockchain as it can not be centralized by a POW algorithm (whoever has the fastest rig). The block reward for POS is subjected to how many native tokens are held within a node this could again put people at a disadvantage if they do not have the funds to buy and store native tokens on their node (home computer).\n\n\n![image.png](https://cdn.steemitimages.com/DQmS82X1MfNsJLpuFnqz7YHNqGQkNgcewfnk5XviLgESigX/image.png)\n\n\nConclusion:\n\nA blockchain can be operated and updated via two main consensus algorithms (POW and POS). Although other algorithms are currently being investigated these are the two main algorithms. POW was the first algorithm used in the first-ever Blockchain discussed in Satoshi Nakamoto’s white paper. The main incentive of a POW algorithm is to be rewarded in block rewards that hold real-world value. The POS algorithm encourages a person to buy the native tokens associated with that Blockchain and store them on to a node with the hope of being rewarded more of those native tokens (A block reward). Evidence shows that the POS algorithm is the better algorithm on many factors. In the future, it appears that most algorithms may move to a POS algorithm. Although some older Blockchains will always be POW as they were never designed to be operated by the POS algorithm.",

What is blockchain technology and its history, what advantages could blockchain technology offer for the average person? The uses cases for a smart contract. How will Blockchain technology be integrated into our ever-increasing digital world and the new age of the Internet of things (IoT). \n\n\nIntroduction:\n\nDecentralized Digital Currencies: \nThe concept of a digital currency has been in development since the 1980s. One of the first examples and widely used digital currency of its kind was called “E-gold” launched in 1996 by Dr Douglas Jackson it aimed to digitalize the value of gold which could then be sent worldwide used as a method of payment via the early internet age. Within a 10 year period, five million people had open active accounts with E-gold and at its peak in 2006 E-gold was processing more than US$2 billion. However, E-gold suffered from a major fault the first being that it was governed by a centralized entity (Gold & Silver Reserve Inc) that oversaw the system and that it was using Microsoft Windows as its operating systems which meant that was open to hacking and phishing attacks.\n\n\n![2020-11-24T133928Z_788862449_RC2P9K9XL48K_RTRMADP_3_CRYPTO-CURRENCIES.jpg](https://cdn.steemitimages.com/DQmebCfAR1jxidsoNmm1NEA7jdvFpMDFt6sRsw85kwQn1N4/2020-11-24T133928Z_788862449_RC2P9K9XL48K_RTRMADP_3_CRYPTO-CURRENCIES.jpg)\n\n\nBitcoin: \nFollowing the global financial crisis (GFC) in 2007 there was now a new push towards developing a truly decentralized digital currency one that was open source, capped at a finite limit and operated on a secure network other than Windows to keep digital hackers out.  \n\nBitcoin is crowned as the world’s first cryptocurrency. It came to the public’s attention in 2009 when a person referring to themselves as “Satoshi Nakamoto” registered an internet domain under the URL name of bitcoin.org. Within the webpage was a link to a white paper titled “Bitcoin: A Peer-to-Peer Electronic Cash System” where the use of Bitcoin was first proposed. The official Bitcoin whitepaper is still available to be read on the webpage which is highly recommended. \n\n\n![Blockchain1.jpg](https://cdn.steemitimages.com/DQmb7JWjkuoGCLt7DpiUi9Qor9EaP1r6VWiwUEPrCbVXvqW/Blockchain1.jpg)\n\n\n\nWhat is blockchain technology:\nWhat really made Bitcoin truly revolutionary was not the Bitcoin itself but the Blockchain technology in which Bitcoin moved on. A Blockchain is a method of permanently recording digital information on to open-source data blocks, much like an open-source ledger meaning that anyone on the network can view the data entries in near real-time.\n\nBefore any new digital data is recorded to a block a number of nodes on the network must cross-reference the newly recorded data. These nodes are in fact other computers on the network located all over the world that are used to validate the Blockchain. The Nodes are surveying every single new data entry that takes place on the Blockchain. If at any one time these nodes detect that there is a discrepancy within a data entry (one nodes data entry is not matching the other nodes data entry) then the Node will not allow the data entry to be recorded. An example would be a digital voting system whereby the nodes must all vote in the same direction and all concur on the same data that they have received. Once a block is filled with data that block is then timestamped and \"Chained\" to another block using cryptography mathematics hence it’s given the name “Blockchain”. This method of security makes a Blockchain very difficult to hack, delete or edit the data once it has been inputted into a block and it is a fact that to this present day the Bitcoin Blockchain has never been hacked due to the enormous computing power and cost that it would take for an external force to hack every single node on the network simultaneously. \n\nAdvantages of blockchain technology to the average person: \nThe Internet of things (IoT) is a broad word to describe the new digitalised world in which we are entering whereby smart houses, cars, drones and computers are all fitted with sensors accumulating data, even your smartwatch is collecting external data right now. This data will then be exchanged with other devices and systems over the world. As this data expands at an exponential rate over time there is going to be a greater emphasis to document and store this data in a secure way. \n\nForbes magazine stated in a 2020 article that Blockchain technology was predicted as one of its defining technologies in the next decade describing it as a super-secure method of storing, authenticating, and protecting digital data.\n\nVoting: \nVoting by ticking a piece of paper with a pencil currently feels absurd knowing that anybody can easily manipulate the vote with the potential of changing a government in their favour by rubbing out the pencil tick with an eraser. Digitally voting on a Blockchain will become secure and truly democratic due to its transparency and security. It will be nearly impossible to tamper or rig an election restoring public trust and faith towards a government. It could also have huge positive implications for 3rd world unstable countries where a dictatorship has been in power for far too long. \n\n\n![download fake.jpg](https://cdn.steemitimages.com/DQmc2LkkK8qLs43NMLK8vJRQKZWMzQbLCGevVT9uhCxXcCQ/download%20fake.jpg)\n\n\nFake News: \nOver the years there has been an explosion of “Fake news” whereby some of this news completely violates common knowledge i.e. The Earth is flat?? Fake news could be stamped out and only trusted resources from respected media outlets could be documented on to a Blockchain freely available to the public to review. \n\n\n![images computer.jpg](https://cdn.steemitimages.com/DQmRKyfsJ8mzTsQpy2g4P336SiJwpCCeGuGbf9Kzt5ttuvt/images%20computer.jpg)\n\n\nBlockchain technology:\nBuilding and operating a supercomputer is extremely expensive. As of June 2020, the Fugaku computer located in Japan holds the title of the world’s fastest computer. Its construction costs topped US$1 billion and it has ongoing operating costs. Supercomputers have many uses cases such as weather prediction, climate research, and medical drug research. Currently, computer scientists are suggesting that idle desktop computers could be put to work by processing small packets of scientific data effectively renting out the idle computers CPU then allowing the computers to send back their scientific results via a Blockchain. This method could lead to greater scientific breakthroughs and would reduce the need to build and run yet more expensive supercomputers. \n\n\n![download car.jpg](https://cdn.steemitimages.com/DQmWubzib5Vi3pZmbp3hCermK63TsU8ovBhbZtsR2x5ZYMv/download%20car.jpg)\n\n\nSelf-driving cars:\nAutonomous vehicles (AV) are already available although they are still in their infancy and must oblige by strict road rule conditions, their use cases make perfect economic sense. An autonomous truck for example has the ability to travel long distances without having to stop for rest breaks and would only have to refuel. Transport costs and time could be reduced dramatically. Road accidents claim millions of injuries and deaths every year with huge economic implications. Studies have found that about 90% of these accidents can be contributed to human error. However, the underlining software of an autonomous vehicle has been addressed as a potential threat posed by computer hackers which have already been demonstrated in test conditions whereby a Tesla vehicle in autonomous mode was deliberately hacked, and its guidance system was overtaken by a 3rd party. A nightmare scenario would be a computer hacker taking control over a major transport network to their advantage. Now major car companies are looking towards Blockchain technology to stop this from ever happening by verifying every software update which the autonomous vehicle receives therefore preventing any modified or malicious software which hackers could implant into the software update. \n\n\n![download donation.jpg](https://cdn.steemitimages.com/DQmcFyYrdJXVFgftzKzdD9E3kBVFzZzRzkayy8xpwS96USW/download%20donation.jpg)\n\n\nDonating money to charities:\nCurrently when fiat currencies (the USD) are sent to charities particularly overseas a lot of the money will be lost on international transaction fees. Unfortunately, sometimes this money does not go directly to the intended charity and ends up in the hands of corrupt governments or organized crime. Blockchain technology can be used to send a synthetic version of a “stable coin” most likely pegged to the USD which is running on a Blockchain. Using this method, it is now guaranteed that the funds will be sent to their intended charity and at a lower transaction fee. \n\n\n![images house.jpg](https://cdn.steemitimages.com/DQme2EZTBP8ZCLWFQqNDukfV68hkJHhrUnk5JCeStjXynVW/images%20house.jpg)\n\n\nBuying real estate:\nLooking back at the American housing bubble that led to the global financial crisis (GFC) it's easy to see how greed and a lack of transparency within financial industries had catastrophic consequences. Blockchain technology provides the public with transparency as to where the transactions are going and builds added trust. \n\n\n![download contract.jpg](https://cdn.steemitimages.com/DQmdvT1izFm6Fb1P5UFaR45wzUctNdUvnE7SDr8G1iQSByC/download%20contract.jpg)\n\n\nSmart contracts on a Blockchain: \nA smart contract is a digital electronic protocol running on a Blockchain. It must be noted that the Bitcoin Blockchain is not capable of running a smart contract as its blockchain protocol was never designed in that way. Smart contracts are effectively taking Blockchain technology to the next level whereby it is used to execute a set agreement that will execute when certain parameters within the agreement are met. One of the Blockchains that is capable of supporting smart contracts is called “Ethereum” founded by Vitalik Buterin in 2015 in which its native token is called ETH. Smart contracts could be used when purchasing expensive real-world assets such as a house or a car, they use a peer to peer purchasing method meaning that there is no need for the involvement of a bank, real estate or lawyer (no 3rd party). In the simplest of terms, a smart contract agreement could look like the example below. \n\n“Person A wants to buy a house from Person B. When Person A pays Person B the sum of 300 ETH as the agreed payment then Person A will receive ownership of the house”. \n\nOnce this smart contract has been executed it cannot be reversed and Person B will receive their 300 ETH as payment for the house. Using a smart contract both parties have saved money by not having to pay real estate commission fees or lawyer fees. \n\nDisadvantages of Blockchain technology: \nBlockchain technology is known for its security however it is theoretically possible to hack a blockchain whereby a hacker needs to gain more than 51% of the blockchain nodes on the network (the computers that are constantly validating the blockchain). This has already occurred to smaller blockchains in the past however the more established Blockchains such as Bitcoin's and Ethereum's using this hacking method is very difficult due to the sheer number of nodes already operating on those networks.  \n\nDiscussion: \nBy reviewing the current data, the Internet of things (IoT) is predicted to be a $1.1 trillion industry in the USA alone by 2022. Data has been increasing at an exponential rate and with the introduction of new infrastructure such as 5g towers, this influx of new data is not going to slow down. It is predicted that Blockchain technology will play a major role in the integration of the IoT by guarding against hackers, gaining public trust through its transparency, the security of documenting this digital data and its ability to move the data worldwide. Now both governments and private companies are looking at the potential benefits that Blockchain technology could offer them. It has been noted that it is possible to hack a Blockchain, but this would mean gaining the power of more than 51% of the blockchain nodes which requires extreme computer processing power and it is costly. Blockchain technology is still evolving and still, public education is needed before the majority of the public understand it. With the few known disadvantages of Blockchain technology, it is obvious that the positives are currently far outweighing the negatives. \n\nConclusion:\nBitcoin was the first-ever cryptocurrency made available in 2009 acting as a proof of concept that Blockchain technology works. The Bitcoin Blockchain is limited in its use cases and more time is need for more advanced Blockchains to become available. \nData is growing at an exponential rate as we enter the information age and now there exists a need to document and process this new data in a secure and decentralized method.  \nBlockchain technology is appearing as a vital link to integrate the Internet of things (IoT) by offering a method of security and transparency. \n\nRobert Lavington",

      "body": "Investing in Cryptocurrencies,\nExchanges and Security.\n\n\n![image.png](https://cdn.steemitimages.com/DQmdp8jYZe3TN7SjEBc4hf4GaUBRrfhogqHgKKHgz2JfJMP/image.png)\n\n\nHello, again crypto friends and welcome to Blog number 2. \n\nTo recap on the last blog, we spoke about Satoshi Nakamoto's white paper, what are blockchains, and the case for Bitcoin for the real world.\n\nSo, today I wanted to talk about investing in cryptocurrencies, exchanges, and the very important topic of security regarding your coins. \n\nFrom my first blog, you should now have a basic grasp of what a cryptocurrency is and how it uses a Blockchain to move from computer A to computer B. For those of you who have made the extra effort to learn even more about this fast-moving technology well done to you all. \n\nWith that said you all now feel ready to invest your hard-earned fiat currencies in cryptocurrencies and make amazing returns on your investments. Not so fast, it must be noted that as of the year 2021 there are currently 4,000 different cryptocurrencies available to choose from (that's right Bitcoin is not the only cryptocurrency available to investors). So, which one should I invest in I hear you all cry? Well, that is completely up to you. As with any sort of investment, there is always a certain element of risk and cryptocurrencies are no exception to this fact. \n\nIn this new world of crypto, you're going to hear the term \"DYOR\" (Do your own research) quite a lot. Never at any point within my blogs am I going to say to my readers that you should invest your fiat currency into a certain cryptocurrency because to put it simply I cannot predict the future. If I knew that a certain cryptocurrency is about to increase in value by 200% and there is absolutely no risk to your investment then obviously would invest every cent that I had into that coin then retire on a beach in the Bahamas sipping cocktails for the rest of my life, unfortunately, I cannot. I can however advise you on ways to minimize your risk thus helping you choose that killer coin that is going to reap those big rewards. One of the ways to do that is to \"DYOR\". Below are some basic concepts that you should be looking for before investing.\nWho is leading the project and what is their credential background? \n\nFor example, I consider myself as a very conservative investor therefore I would be very cautious of a newly launched cryptocurrency being led by a CEO who has no experience in the industry and does not hold any prior credentials. To state the obvious if a CEO does not know what they are doing then there is not much hope for the rest of the project. In today's world, a person can easily be researched on their employment background using online tools such as LinkedIn or a simple google search. Finding out who the CEO is and how respected they are within the crypto industry is a priority before any investment is made to minimize your risk. \n\n\n![image.png](https://cdn.steemitimages.com/DQmSbhUXCeSZXGPB9xMyoCXX4LXgZeRmby3HwW9ntXrMu7u/image.png)\n\n\nExample 1: \nVitalik Buterin is the CEO of Ethereum which is the 2nd biggest cryptocurrency by cap market value, in 2014 he was awarded the Thiel Fellowship, and in 2018 and he was awarded an Honorary Doctorate by the University of Basel. He is well established and recognized within the cryptocurrency industry and Ethereum has a clear goal of its future focus.  \n\n\n![image.png](https://cdn.steemitimages.com/DQmQwSNvBsAaadeFspAGS6avbNBpmu5MCx5EDf381vY9WFN/image.png)\n\n\nExample 2: \nCharles Hoskinson is the CEO of Cardano, is a mathematician and co-founder of Ethereum. In 2014 he left Ethereum for personal reasons and started Cardano. He holds university degrees from the Metropolitan State University of Denver and the University of Colorado Boulder. \n\nWhat does the project aim to achieve?\n\nUnderstand that the cryptocurrency is backed up by the project that the company is running. For example, ETH is the name of the cryptocurrency coin itself (it is the currency of the Ethereum Blockchain). Ethereum is the name of the project, it is a community-run open-source blockchain that aims to run thousands of decentralized applications run by 3rd parties. \n\nWhen was the cryptocurrency launched and how long has it been in circulation?  \n\nBitcoin was launched in 2009 and is still active to this present day, it still sits at number 1 on the cap market value leader board and is well established worldwide. I would personally give any new cryptocurrencies several months to settle in before investing in the project. That way it gives the community time to understand the new coin and if the worst-case scenario occurs and the coins turn out to be a scam then this should be identified early. Remember that If the project is backup by absolutely nothing then the chances are high that the price of their cryptocurrency will do just that, absolutely nothing. \n\n\n![image.png](https://cdn.steemitimages.com/DQmR4goXeC6iHa9Yy8mAyUdrxyHs1EQega1bfeVYHswg7pr/image.png)\n\n\n\nWhere does a person buy cryptocurrencies from?\n\nSo, congratulations on getting this far, you have completed your \"DYOR\" and you have found the cryptocurrency coin that you wish to invest into. The next step is where do you buy the coin from? A person buys their cryptocurrencies from an online exchange which is a website where a person can buy/sell all types of cryptocurrencies.\nIt must be noted that there are also over 200 different exchanges operating around the world. So, which one do you choose from? I use the Binance exchange because at the time of writing it was the biggest exchange in the world and uses some of the best cybersecurity which even some banks would envy so I have been told. Their user interface can be a bit tricky to master especially for a beginner but there are plenty of YouTube tutorials to help you navigate your way through. \n\nSo, once you buy your crypto what do you do with it now? That again is your own decision to make. You can choose to Hodl (Hold On for Dear Life) in the hope that years later your coins are worth a small fortune. Or you could choose to become a trader, for those of you just starting into the crypto world I do not recommend trading until you have a solid understanding of the industry as this is something that can take many years to master.  \n\nSecurity and Scammers:\n\nAt this point, you all need to pay attention. Market crashes happen all the time throughout the crypto cycle and it would be very bad if your investments lost 80% of their value due to a crash, on the bright side you would still own the coins and there is a chance that the value of those coins could go back up in the future one day so that you could recover your investments. But what would be terrible would be if your coins got stolen effectively taking wiping out 100% of your investment and the chances of you ever recovering your investments is next to zero. \nUnfortunately, where there is money to be made it will attract scammers and I am personally getting quite concerned with the never-ending scammers that pratol social media websites such as Facebook and WhatsApp looking to pray on their next victim. I'm hearing horror stories of people losing huge amounts of money and sometimes their entire life savings through these scams. Last year alone Australians reported a record-breaking $37 million lost to digital scammers and that is just the reported figure. I have no doubt that you have all worked hard to save money for your investments and you all want to enjoy a good retirement, you should not be losing your money to digital scammers. If you use social media websites then the chances are very high that you will in the future be contacted by a digital scammer, so please listen next. If you are new to cryptocurrency then you are at high risk of being scammed. Scammers deliberately target new people in the crypto space because they know that these people are the most vulnerable.\n\n\n![image.png](https://cdn.steemitimages.com/DQmR3Fy9g5xNDXzgDZVA97uG2gyWGpNdtsahf69Kz2RSqYE/image.png)\n\n\nWhat is a digital scammer? \n\nIt is a person who wants to steal from you by tricking you into handing over your money or your personal information fraudulently and dishonestly. So, you're probably thinking that that's never going to happen to me, well you will be very surprised when you realize that some of the smartest people can also fall victim to these scams. Digital scamming is big business and is well organized right up to the state level, yes, the country of Nigeria I'm looking at you! The internet has truly changed the world that we live in, we can connect to anyone in the world however it has also allowed the digital scammer to connect with us and the more digitalized our personal lives become the more open we are to a scammer attack. A person just has to look through their spam email box and I guarantee that there will be an email in there from the FBI or the Prince of Saudi Arabia who has found $10 million which they just so happen wish to share with you. \nHere are some very basic rules to keep yourself safe: \n\nRule number 1: If it sounds too good to be true then it probably is. In other words, if a person contacts you claiming to be able to mine you 10 bitcoin per day which is equal to USD 10,000 every day for the rest of your life and there is absolutely no risk then I would say that it's highly likely a scam, simply block them on the medial platform and report them.\n\nRule number 2: Trust no one online who you have never met in person before. It is all too simple for anyone to set up a fake Facebook account and then start calling themselves Doctor Bob who is head of the US Federal Reserve. A scammer will contact you will their typical statements of wanting to help you make millions of dollars. Ask yourself this question, why would they be wanting to help you become a millionaire, and what is in it for them? Look at their spelling and grammar, I would expect a person who claims to be from an English-speaking country not to have any spelling mistakes in their sentences and have good knowledge of their own countries geographics. \n\nRule number 3: As stated above always do your own research on a cryptocurrency before you invest, read through its white paper, and understand what the project is trying to achieve. But remember that no one really knows what the market is going to do. If a person claims that a certain coin is going to be worth a small fortune in the future approach it with caution.\n\n\n![image.png](https://cdn.steemitimages.com/DQmUaHzuPc8MbaUfi7pRV2F5qACcVEyVJhbd7miH37Sokiu/image.png)\n\n\nWhat is a phishing scam? \n\nA phishing scam is another form of scam but this one is email or tx messaged based (Think fishing = Phishing). For those of you who think that your safe because you don't use any form of social media think again, you are still vulnerable to attack. It is basically a fake email or tx message that is a near replica of the real thing such as a banking email, cryptocurrency wallet, or government website. As with making a fake Facebook account, it is again all too easy for a person with good computer skills to copy a legitimate webpage and then design a fake email from that webpage. These phishing scams will be asking you to input your personal details, banking details, or crypto details. Since these phishing scams can closely resemble the real thing it can be sometimes very difficult to spot them apart however are a few red flags to look for:\n\nDo not click on any links or open attachments from emails that have come from an unknown address. \nGoogle search the names of the companies within the email, have other people heard of this company before and what does it do? \nHave you been contacted out of the blue and is the email threatening you?\nUnfortunately, already a lot of our personal information is freely available to scammers who use the dark web. The best security is yourself, be vigilant and stay up to date with the latest scamming attacks. \n\nBelow is a basic example of a \"phishing\" email or tx message that you could receive in the future: \n\nhttps://SupportZryptocurrencyInvestment.com \n\nDear Client, \n\n!WARNING! \nYour account has been hacked! In order for us to maintain the safety of your cryptocurrency and your personal information, you must open the link below immediately. \nFailure to do this will result in your cryptocurrency being stolen! And there is no way to get it back!\nYou must provide your personal details to us now or else!  \n•\tYour Name: \n•\tDate of birth:\n•\tAddress: \n•\tYour password: \nYours sincerely from the CEO.\n236 Greens Street, New York City, USA.\n\nThere are so many red flags that stand out within this email \nLook at the URL, there is a clear spelling mistake of the word \"Cryptocurrency\" spelt with a “Z”?? \nA CEO of a large company is hardly going to have the spare time to contact you personally. \nThis email is obviously generic because it is not addressed to you personally and is not using your full name. \nThe company is asking for personal data which it should already have access to if you are one of their clients. \nThe email is not written professionally.\nNo company is ever going to threaten you into handing over your personal data and certainly is never going to ask for your password.\n\nResearch the physical address at the bottom on Google Maps, does that address really match up to the location of the company that it says that it is? \nWhen it comes to investing in cryptocurrencies remember that your family, your health, and your house whole bills always take priority over cryptocurrency investing. You only ever invest what you can afford to lose, you would never go to your nearest casino and bet your entire life savings on \"Black\". Be responsible with your finances, stay safe out there, and help the new people who are coming into the crypto world.\nRob 😊",

It has been constructed in a way to give the reader multiple different comparisons and examples for their individual learning. \nIt will touch on the history of Bitcoin, the basics of BlockChain technology and Cryptocurrencies in general. \nSo first let me thank you all for stepping out of your comfort zone and showing the willingness to learn something new, so now let’s get started to learn this new industry together. \n\nAt present, if I stopped a person in the streets and asked them to name me a “Cryptocurrency” the answer that I would most likely get back is “Bitcoin”. Then if I asked them to follow up questions such as “what exactly is Bitcoin” and “How useful is it to the average person”? the most likely answer I would get is “I don’t know”? Conversation stops right there!\nSo, let’s get down the to bare basics and answer the pending questions. It's first important to understand where did Bitcoin come from and what was the original purpose of its invention. From my research and findings, I have concluded that Bitcoin came as a direct result of the global financial crisis of 2007.\n\n\n![image.png](https://cdn.steemitimages.com/DQmZzzwheQUtxjEjC4Mz7o4en55TtFNG96UWQEsCeYYtyUL/image.png)\n\n\nThe global financial crisis (GFC):\n\nIn a nutshell, the GFC occurred in America because American banks were lending out too many mortgage loans to home buyers who were deemed to be high risk (Sub-prime) in the sense that they had no form of a deposit to secure the mortgage loan and the chances of them being able to service the monthly repayments were very low. Interest-only loans were regularly given out to new home buyers in the hope that the housing market would continue to increase in price. Basically, the home buyers started to default on their mortgages when the time came for them to start paying back the principal of the loan (the total amount borrowed) which then forced the banks to now start to repossess their houses. House prices throughout America started to depreciate and the banks were stuck with a house that was worth much less than what the original price that was paid for it and no one wanted to buy these houses. To makes matters worst the banks began to sell these mortgages off in the forms of government bonds to other foreign banks around the world, effectively moving the debt off to other parts of the world and doing this without the permission of the homeowners (think of play a game of catch with a live hand grenade and the pin has been pulled!) Between the periods of 2007 and 2009 during the peak of the crisis major banks within America and throughout the world had filed for bankruptcy, they were unable to recoup their funds which had been lent out and the modern banking system was close to failing. Instead of letting the market go through a natural course of correction by letting these banks go bankrupt governments around the world made the move to bailed them out using taxpayer’s money. My own opinion on this matter is that the governments should not have intervened, the banks were irresponsibly lending out mortgage loans to people with bad credit history in the hope that house prices continued to grow in value. Clearly, this did not happen and the average taxpayer had to foot the end bill because of the mistake that banks had made. \n\n\n![image.png](https://cdn.steemitimages.com/DQmNb2nEAHRvnen9sTAJgnNhRRDLgkmJTbfwu8yXgQstnHi/image.png)\n\n\n\nSatoshi Nakamoto white paper:\n\nIn 2009 an internet domain was registered under the URL name of bitcoin.org by a person calling themself “Satoshi Nakamoto”, within the webpage was a link to a white paper titled “Bitcoin: A Peer-to-Peer Electronic Cash System”. It is within this white paper that the idea of a “peer to peer” transaction method of sending “Electronic cash” from one computer to the other is discussed without the need for any 3rd party financial institution using a new technology called “Blockchain”. It must be noted that peer to peer transactions is not a new idea as they were it was first used back in 2002 by PayPal. However, what is a new idea is running the “peer to peer” transactions on a blockchain platform that is independent of any 3rd party. The paper is set out in a standard university layout such as an abstract heading, the the body of the review, the discussion, and ending with a conclusion proving that whoever wrote this paper must have already been a post postgraduate and had a good working knowledge of computer science. Whether Satoshi Nakamoto is a man, women or a group of people this person remains anonymous to this present day. There is speculation that Satoshi Nakamoto is in fact a British national due to the slang British words that were written within the paper and the perfect grammar and spelling due to very few Japanese people able to speak perfectly good British English. Throughout the Cryptocurrency industry, Satoshi Nakamoto is credited with creating blockchain technology where a bitcoin is able to travel on the blockchain to its intended address. \n\nWhat is the blockchain:\n\nThe technical explanation is that the blockchain acts as a storage of blocks containing data linked together in a chain that is open source in the sense that any person on the system can view the data within the blockchain. \nSo, to put that into more layman terms let’s play a game. I’m going to invite 10 of my friends around to my house to play a game of cards. The type of card game that we are going to play is irrelevant to this scenario but this game will involve all 10 of my friends having to put down physical money to bet whilst playing the game.\nBut just by sheer coincidence all 10 of my friends have all forgotten their wallets and so no one has any money to play the card game including myself. However, I come up with an amazing idea, I get a huge piece of paper and I place it into the centre of the table, this piece of paper is now called a “Ledger”, and this ledger is going to track every single time a person who is playing the card game places down a bet, how much that person has bet and who has won the round. The ledger is going to be open source meaning that anyone who is currently playing the game can see all the information written into the ledger. \n\nSo, let’s start the first round and my bet is going to be $5,000, remember that I also have forgotten my wallet, so I can’t physically put down $5,000. So, I then physically write the number $5,000 into the ledger so that everyone else can see that I have just made a bet (open source). Now my other 10 friends do exactly the same thing of writing their bets into the ledger (open source) and we can now play the card game. \n\nSo, let’s just say that I won the first round of the game and the total amount that I have won is now $50,000, I do not physically collect $5,000 I do the same again of writing my total winnings of $50,000 into the open-source ledger, I hope that you’re all with me so far. Now we play a second round but this time I lose the round and my friend “Bob” wins the round. Bob then writes his total winnings into the ledger. Do you understand what’s going on here? At no point can I, Bob or any of the other 9 friends that are playing the game have the ability to cheat the system by means of changing around the numbers on the ledger to make it seem that they have won more money than they really have. Why? Because everyone playing the game will see straight away that the numbers have been changed.  It’s basically the responsibility of the players within the game to make sure that every transaction is legitimate and that no one tampers with the open-source ledger in the centre of the table, also if one of the players makes a mistake within the game then we have the ability to go back through the ledger and resolve any discrepancies. So, let’s take this one step further if I hand over my car keys to my friend Bob everyone within the game has all seen what I have just done and they all write within the ledger that “Rob gave his car keys to Bob.” What we have created here is a system where I can hand over anything to any 10 of my friends within the game and every one of those players will effectively sign off on to the ledger allowing the transaction to go through. \n\nSo now let’s replace all my friends with computers and now let’s call these computers “nodes”. Every single time a person on the network sends any sort of data it’s the responsibly of these nodes to validate the integrity of every single transaction. If there are any discrepancies flagged by just one of the nodes on the network then the transaction fails. All of this transactional data is then timestamped or stored up into something called a “block” hence the given name “Block-Chain”. \n\nThe first-ever blockchain that Satoshi Nakamoto proposed within the white paper was for the movement of digital currencies called “cryptocurrencies”. Bitcoin is called a cryptocurrency because of the very clever mathematics it uses called cryptography which is beyond the scope of this blog to explain. The basic concept is that Bitcoin moves on the blockchain the same way a car drives on the road. \n\n\n![image.png](https://cdn.steemitimages.com/DQmPKaw4NeT8zW6WxfNh2HRZWmFsGtquouwf65TXqNc9iqL/image.png)\n\n\nIs Blockchain a secure network:\n\nAs with anything digital one of the first things we typically think of is security, how safe is this Blockchain system and can it be trusted? So, let’s just say that a hacker wants to alter the blockchain to their advantage and steal some Bitcoins from other people. If the hacker somehow tried to alter the blocks of data the other blocks would no longer align with everyone else's copy. When the nodes cross-reference their copies against each other they would see straight away that there is one copy outstanding and that the hacker's version of the chain would not be seen as illegitimate. Yes, it is theoretically possible to hack Bitcoins Blockchain however such a hack would require the hacker to simultaneously take control and alter 51% of the copies on the blockchain. For such an attack to succeed it would require an immense amount of computing power which is impossible even for the world’s fastest computer of today. It is a fact that to this present day the Bitcoin Blockchain has never been hacked or taken control of. Where people are talking about a “Bitcoin hack” most likely they are talking about the exchange where their Bitcoin has been stored has been hacked which has nothing to do with the Bitcoin Blockchain. Blaming an exchange hack on Bitcoin would be like blaming the Australian dollar because your bank account got hacked, it’s not the dollars fault it’s the bank's fault. So, I would like to reiterate again that Bitcoin’s Blockchain has never been hacked. \n\nThe case for Bitcoin:\n\nSo, what do we have here? We have an open-source blockchain that can send a bitcoin (Cryptocurrency) to anyone in the world securely. So how can that be beneficial to the average person?  \n•\tBecause there is no middle entity when sending a bitcoin (peer to peer), the overall cost of sending bitcoin is far cheaper than that of sending fiat currency the traditional way whereby the transaction has to go through a 3rd party to be authorised.\n•\tBitcoin is universal the fact that it does not matter if you are from Australia, Europe or South America. Bitcoin holds its value no matter where you are in the world.\n•\tOnce you own Bitcoin you truly become the owner of that Bitcoin and have autonomy over your own wealth whereas fiat currencies are controlled by governments and banks. \n•\tThe Bitcoin Blockchain has proven itself to be a reliable security sound. \n•\tThere will only ever be 21 million Bitcoins in circulation meaning that Bitcoin is becoming a scarce asset and is immune to inflation as central banks cannot just print more of it as they can do with fiat currencies. This means that in theory, the purchasing power of bitcoin will go up over time.  \n\nSummary: \n\nBitcoin was the first-ever cryptocurrency to use a Blockchain network. Since its invention in 2009 Blockchain technology has improved drastically and at the time of 2020, there were 861 other Blockchains operating completely independent from Bitcoins Blockchain. In my view, I see Bitcoins Blockchain as just a proof of concept that the idea works, and it is slowly gaining adoption throughout the world. However, what if we could take this to the next level. What if instead of just sending individual Bitcoins to each other on a very limited Blockchain what if we could have a full contract on a blockchain where that contract stated that a real-world asset belongs to me such as a house or a car and because the contact is on a Blockchain it cannot be altered or changed, it could be called a “smart contract”…………….. Ethereum.\nThat’s for the next blog! \nRob Lavington",

Currently it’s no good having all these new crypto services and industries available if the average person does not understand how they are used, what they do and how are they could be beneficial.\n\nWithin my blog I will try and explain these new services and industries using multiple different comparisons which I hope at the end of this blog you will all have a better understand. \n\nSo, let’s get started,\n\nWhat is DeFi?\n\nLending money, borrowing money and earning interest on money are all forms of a financial service. The word DeFi stands for “Decentralized Finance” and the answer is within the name itself. It is simply any financial service or financial sector which works for its customers in a decentralized way. DeFi means that there is no one central entity that controls the financial service, the service is controlled by the computer algorithm or a smart contract in which it is written.\n\n\n\n![image.png](https://cdn.steemitimages.com/DQmNtVeuEETcep6bgqWN3DuydE3ZTBLU7YvT5MaHW1FeGR1/image.png)\n\n\n\nWhat are smart contracts: \n\nVitalik Buterin the CEO of Ethereum and his team created the Ethereum blockchain in 2015. This blockchain is open source meaning that it is open to anybody with programming skills who wants to write any applications on top of the Ethereum blockchain, these applications can also be called “smart contracts”. Much the same as Microsoft Word runs on top of the Windows operating system of a PC or the game \"Angry Birds\" an application running on top of the Apple IOS operating system.\n\nIt must be noted that smart contracts are not a new idea as they were first proposed back in 1994. However, what is a new idea is running a smart contract on a blockchain platform. In Vitalik’s own words he describes a “smart contract” as being like a vending machine in the real world. You insert your money into the vending machine and a soda drink comes out because that’s what the vending machine is designed to do, that is the protocol in which it is running. So, a vending machine can be seen as a physical device that executes a smart contract when it is told to do so and does not deviate away from that contract. However, in the real world a vending machine can malfunction, and it can break down. By digitalizing this concept and running the smart contract on a cryptography blockchain such as the Ethereum blockchain it makes these smart contracts far more secure, reliable and powerful. It must be noted that the vast majority of all DeFi services and projects are currently running on top of the Ethereum blockchain.\n\n\n\n![image.png](https://cdn.steemitimages.com/DQmVxHKN7QvrkCsk93pmV87NfekbqW9JxuqBandg2KnkMe5/image.png)\n\nPeer to peer (p2p): \n\nOne of the most exciting concepts of a smart contract is the removal of the “middleman” during any financial matter and promoting the idea of “peer to peer” services. Currently if I wanted to buy a house from my friend Bob we would both have to run the process through a real estate and then through a lawyer to make sure that the process has complied with the local law, these two services would take their commission fee before the final settlement of the property which can be as high as 6% of the sale price! A peer to peer service would work in both myself and Bob’s favour by removing the real estate and lawyer from the process thus saving us both the 6% commission fee. A peer to peer” service would be much more cost effective to the consumer than the current system and much faster because the real estate and lawyer’s paperwork jargon are all compressed all within the smart contract itself.  Once the smart contact is signed off by myself and Bob the smart contract excuses itself (Think of the vending machine and the soda drink coming out once money has be deposited). Now think more border, using this same peer to peer method of buying a house there would be nothing stopping you from purchasing a house oversea in the Bahamas and avoid paying the other fees. While you are not living in the house you could complete a rental agreement with another person, the agreement would be on the blockchain as a smart contract where by you know that you will always be paid rental funds while your new property is occupied. \n\nCentralized Finance:\n\nAn example of a centralized financial institution would be a bank. A bank is run by a CEO whose job is to look after their customers and run the business of the bank to make a profit. Within Australia, we have many banks all running independently from each other. Above the banks is the Bank of Australia (RBA), it is the RBA that sets the official interest rates for the rest of the banks to follow. Other countries around the world have a similar banking structure. But the point is that the RBA is controlled by a single centralized entity, at the end of every month a meeting will be called, and the centralized entities will discuss whether to raise or lower interest rates. \nIn the DeFi world there is no centralized entity making these decisions and most importantly there is no 3rd parties involved. The decisions are made by the market itself and the main purpose of the DeFi industry is to remove the need for the 3rd party and create the new peer-to-peer financial system. \n\nDeFi within the Crypto industry:\n\nAn example of DeFi within the crypto industry would be a DEX (Decentralized Exchange). Currently the majority of crypto exchanges today are still centralized, so this means when you buy any cryptocurrency using these centralized exchanges the exchange will take a trading fee much the same way how a broker takes a fee whenever you buy or sell shares using their platform. Also, this centralized exchange is going to have in place a KYC (Know your customer) protocol whereby a customer’s identity and their financial activities will all have to be disclosed to the exchange. One centralized exchange (whose name I will not mention) will block customers who are located in the USA and simply will not allow them to use their exchange at all, putting them at a clear disadvantage than others.  \n\n\n\n\n![image.png](https://cdn.steemitimages.com/DQmeiVZuhk4ygd1BAYHG8XFd4jwk7qkKuM2dKJkYZEG9EA2/image.png)\n\n\n\nWhat is Uniswap: \n\nThe most popular DEX right now is the Uniswap platform. Uniswap is simply a crypto exchange platform running on the Ethereum blockchain. But the major difference is that this exchange is decentralized (DEX) meaning that there is no customer support or any single entity running the exchange. It must be noted that when a customer uses the Uniswap exchange they are only able to buy ERC20 tokens. This means these are tokens that only run on the Ethereum blockchain and you must use ETH to buy these ERC20 tokens. A person cannot buy Link (which is an ERC20 token) using Bitcoin because Bitcoin runs on its own blockchain which is completely separate and different to that of Ethereum’s blockchain, the two are not interchangeable. \n\n\n![image.png](https://cdn.steemitimages.com/DQmfUXqd5bkEnJSfC6p7Q3tRnw2YPxqs8eHzyxUDMpCBu2v/image.png)\n\n\nWhat is an NFT? \n\nNow stepping away from DEX’s and talking about NFT’s\nThe word NFT stands for “Non-Fungible Token”. So, let’s break this down and understand what the word “Fungible” actually means. \nThe word \"Fungible\" has the same terminology as the word \"Asset\", this can be a real-world asset such as a car or a house or a digital asset such as a Bitcoin or ETH.\n\nFungible:\n\nWhen something is “Fungible” it means that it has the same value as another fungible token of its kind and it is interchangeable with that other token, but it is NOT exactly the same.\nTotally confused right? Let me explain. \n\nExample 1: If I swapped my $10 note with my friend Bob, and Bob gave me back his $10 note then we would have both received the same amount of value back in both back our pockets. However, the two $10 notes that we just swapped with each other would not be exactly the same, meaning that they would not have the same security codes written on the back, so they are called “fungible” tokens, in the sense that they are interchangeable or fungible.  \n\nExample 2: If I swap a 1kg rock with Bob and Bob gave me back his 1kg rock both the rocks that we just swapped are not exactly the same but still we have exchanged our rocks and we both agree that both our rocks hold the same amount of value as each other, they are interchangeable or fungible.\n\nExample 3: If I swap my pet camel with Bob’s pet camel, we would both be getting different camel’s back in return, but we have both accepted that both our camels hold the same amount of value, they are interchangeable or fungible.\nThe bottom line is that anything that is “Fungible” means that this fungible asset can be exchanged for another asset for the same amount of value and there are many of those assets available. I hope that makes sense. \n\nNon fungible:\nA “Non fungible” asset as you guessed it would be the complete opposite of a “fungible” asset. It is something that is very unique or rare and it is not interchangeable because it has its own unique value. \n\nExample 1: Would be the Mona Lisa painting designed by the one and only artist Leonardo Da Vinci. To the best of my knowledge this painting is priceless and it could never be swapped or interchanged with another painting of its kind, there is only one Mona Lisa painting. Copies could be made of the Mona Lisa, but those copies would never hold the same priceless value of the true original painting, It is a Non fungible asset. \n\nExample 2: A Ford and a BWM are both cars, but they are not the same make and model of car. A BMW is generally worth a lot more than a Ford so if I tried to swap my 1980s Ford with my friend Bob for his 2020 BWM then I would generally be getting myself a better deal. Bob would be crazy to go through with the swap and so it is cancelled, and his BMW is Non fungible. \n\nExample 3: A first-class plane ticket on a private jet to Dubai is very different to an economy cattle class ticket to Sydney. Yes, both tickets will get you on board a plane but they are both very different to each other and worth vastly different amounts. Bob would not swap me his private jet ticket for my economy class, so these tickets are Non fungible.\n\n\n\nNon-fungible tokens in Crypto:\n\nIn the crypto world when we talk about NFT’s it is a digital asset that moves on a blockchain and as all of the examples above state it is not interchangeable with any other token of its kind.\nA digital NFT is basically a digital asset that cannot be copied or replicated. It would be better to think of a NFT as a digital collectible item. Once you own an NFT no one can take it from you because you will be the owner of the private key. So, try and apply that same thinking as if you own a bitcoin no one can take the bitcoin from you if you are the owner of the private key.\n\n\n![image.png](https://cdn.steemitimages.com/DQmRqc12ppnB5QrUMsjFxAEhSeaGe9bwcMcKJCShTpDmh1p/image.png)\n\n\nSo what could a NFT be? \n\nAt the end of 2020 the video gaming industry was worth an estimated $90 billion and one of the most popular online games was Fortnite. The current problem with gaming is that once a gamer progresses to a new level or they are able to complete the game they are often rewarded with a digital item such as a sword, a shield, a certificate, etc. But those digital rewards are always kept within the game. The gamer cannot take their reward out of the game then use that reward in another unrelated game or put the reward in their bank account. So, image this what if you’re playing a game and you managed to progress to the next level, and you are rewarded with a digital sword. This sword could be in the form of a digital NFT, its completely unique no one else throughout the game has one and you are the sole owner of that one and only sword. You could then be able to remove the sword completely out of the game and put it up for sale using a DEX in which you could sell the sword for Bitcoin, Ethereum or any another digital asset? Life achievements. Let’s say that you have completed a degree at university, and you scored the highest marks in the class. Your degree could become an NFT because its unique with the highest marks. Unique digital collectibles such as digital artwork are expected to become a huge market within the NFT world where a person sell their unique art work on an exchange to any potential buyer. \nMiscellaneous Terminology:\n\nFiat currency: \nAny form of government issued currency that is not backed up by a valuable commodity such as gold or silver to give it is real value. An example would be the Australian dollar, at the end of the day its nothing but a piece of plastic which the government tells you that you must hand this plastic over when you want to buy anything such as a car, a house or shopping. You hand over plastic paper. Lol   \n\nBull Market: \nBasically, means that the market is gaining value, and everybody is making money with positive inflow of volume and buyers. Bull markets are confirmed by higher troughs and higher peaks on a graph. \n\nBear Market: \nIs the opposite to a Bull market, the market is losing its value and people maybe selling off their stocks or assets. [Opposite of above]\n\nLiquidity:\nThe word Liquidity means the total volume of money that has flowed into an asset and how quickly the asset can be turned back into fiat currency. So, a house during a bear market would be considered low liquidity because during a downturn in the housing market very few people would be buying houses, there would not be much money flowing into the housing market and it could take up to a year or longer to sell a house and turn the asset into fiat currency. \n\nI hope that this all make sense. Let me know what you all think. \n\nRob 😊",

But what is the Ledger hardware wallet anyway? It’s a silver USB looking device that holds the private key to your cryptocurrency.\n\nAs far as I’m aware it’s the safest way to store your cryptocurrency because you have full control of the private key. If you choose to leave your cryptocurrency on an exchange or a centralize finance platform then you are taking a risk because you do not have control over the private key. \n\nYou simply insert the ledger into the USB of any computer then let the ledger synchronize your private key with the specific blockchain so that it can locate your coins.\n\nSo why do people choose to have this Ledger device? Because as stated above the ledger holds your private key, think of the private key as a proof of receipt. It’s the only way to prove that the cryptocurrency that you purchased really does belong to you. \n\nThink if you just brought a new car, the company gives you a receipt for that car. Then the next day the car gets stolen. If you have kept your receipt the company can give you a new car. However if  you have lost your receipt, then it’s as if the car never belonged to you and you will never get a new car back. \n\nThe stories and rumours that I have heard so far regarding the Ledger data breech is that the Ledger company had their customers data stolen by hackers. This customer data is now freely available on the dark web for other hackers and scammers to access. Not a great look for the Ledger company.  \n\nSo, does this mean that hackers can now steal the crypto coins that are currently stored on a person’s Ledger hardware wallet? Not really, the method that these scammers are now trying is called a “phishing” scam. \n\nWhat is a “phishing” scam. It’s basically a scammer who sends you any type of email pretending to be someone else, pretending to represent the ledger company or some other company. They are basically trying to trick you in to handing over your personal information. \n\nSince the data breech there has now been a huge amount of these “phishing” emails sent out to target those people who have had their data stolen.\n\nThese “phishing” email can look and read every convincing. The golden rule is to NEVER EVER input your 24 seed words into the phishing website or any other private information. The Ledger company have made it very clear that they will never ask you for your 24 seed words.\n\nThe 24 seeds words are the backup for your private key. In other words, if you lose your Ledger hardware wallet, your dog ate it, it got ran over by a bus or it got physical stolen its ok because it is protected by a password pin number. (Obviously you never store the password pin number and the Ledger in the same place).\n\nYes, you will have to buy another Ledger but to restore the ledger back to its original state you will have to input those 24 seed words. They are random words such as \"House\", 'Tree\", \"Boat\", \"Cat\". Basically impossible to randomly guess but they must be written down on paper and kept off of any digital device.   \n\nSo, what is a scammer going to do it they got a hold of your 24 seeds words?? Simple, they will reset their own ledger hardware wallet and restore it to your ledger which means that they now have your cryptocurrency now on their own ledger. And now you have just lost all of your cryptocurrency. \n\nSo, I will say it again. Never input your 24 seed words into any website no matter how convincing or legitimate it made seem. Keep your 24 seed words hand written down on paper and keep that paper off of any digital device. \n\nStay safe out there and keep on warning people about these phishing scams. I have no doubt that these scammers are in the process of preparing their next phishing emails.  \n\nCheers guys. \n\nRob",

Well now you can, the platform is called “BlockFi” and the company is based in New York City. \n\nAt the time of writing this blog 1 ETH is currently worth $301 USD, and I strongly believe that ETH could be worth a lot more in the coming years as more DAPPs are run on the platform and more people use DeFi with Ethereum being the under-lining platform. \n\nThis is not investment advice but I think a good idea would be to compound your already existing ETH. The way you do that is to open up a new BlockFi account and send your ETH to the BlockFi company. At the time of writing this blog a new customer with be able to earn 4.5% on their ETH, you simply leave your ETH on the platform and let the ETH earn you more ETH.  \n\n\n![download.jpg](https://cdn.steemitimages.com/DQmes4uB798QQVEvRYL4nsrTGhbyZ952kWRGbGyTrVXp4tv/download.jpg)\n\n\nHowever, this does not come without risk and you must be aware of the risks. The saying in the Cryto world is “not your keys not your crypto”. Which means that you will have to hand over full control of your ETH to BlockFi (or hand over your private key). The worst-case scenario is that BlockFi gets hacked and you will lose all of your ETH. Much like the famous hack on mt gox exchange.\n\n\n![images.jpg](https://cdn.steemitimages.com/DQmemuBot4VYiPezafMdf56Mqr3UyPbEyKNzVzaHafjMRyX/images.jpg)\n\n\nThe good news is that BlockFi are well aware that they are a target and I have no doubt that they will have some of the best firewall protection in place. Also being based in America you can be assured that the BlockFi will have to strict regulations. \n\nWhen you feel the time is right for you please use my referral link: \n\nhttps://blockfi.com/?ref=38507036\n\n\n\n![0_0PO7CHFxu_kdz8QH.png](https://cdn.steemitimages.com/DQmSc8yejteUeb4JaMbFi8CqDrD2pyoou8nt4AXvCt9JA2n/0_0PO7CHFxu_kdz8QH.png)\n\nNever give out your phrase words to anyone and key your private key safe.\n\nCheers guys \n\nRob",

Hope you are all well. \n\nA quick blog this time.\n\nI’m getting quite concerned with the never ending scams and scammers on Facebook regarding Cryptocurrency. I’m again hearing horror stories of people losing huge amounts of money through these scams. \nAgain, lets goes back to the basics of how this all works:\n\nWhat is the public key?\nThe public key is where anyone can send you any sort of cryptocurrency. \n\nExample 1: Much like if “Bob” wanted to receive an email from “Sarah”. In order for that to happen “Sarah” would have to know what is “Bob’s” email address first before she can send any sort of email to “Bob”. Once “Bob” tells “Sarah” his email address its means that “Sarah” can then go on to send “Bob” the email. Makes perfect sentence? \n\nSo, applying that basic knowledge to Cryptocurrency If I wanted to send any person any sort of Cryptocurrency I’m going to have to know what that persons Public Key is first so that I know where to send the Cryptocurrency to. Think of the Public Key as the email address, I cant send you an email if I don’t have your email address. \nOnce you send the Cryptocurrency to another person’s wallet using their public key the transaction can not be undone or be reversed. Once the Cryptocurrency has moved out of a person’s Crypto wallet and on to the Blockchain then it’s gone in transit and on its way to the other designated wallet. The transaction cannot be reversed, only if the receiving person sends it back to you which means that they would also have to know what is your public key in order to send it back. \n\nIs it safe to share your public key with anyone?\nYes, it’s completely safe to share your public key with anyone. The worst thing that will happen will be that a person anywhere in the world would be able to send you Cryptocurrency into your wallet. It’s impossible for a hacker or scammer to steal any Cryptocurrency out of your wallet if the hacker or scammer only has your public key, the blockchain platform simply will not let that happen.  \n\nFor example, below is my public key for my Ethereum wallet please feel free to send me some ETH for this amazing blog! Lol \n\nEthereum wallet address: 0xb2a7abd9fa5de3fc728cb69bd6bb5d3d3f51b438\n\nWhat is the private key? \nThe Private key works in conjunction with the Public key and basically decodes the transaction and is used as the proof of purchase that the coins that you have purchased do really belong to you. \n\nIs it safe to share your private key with anyone?\nNO! do not give out your private key to anyone, that’s why they are called “private” it has to be kept “private”! If a person knows what your private key is then that person has the capability to be able to move and steal all of your Cryptocurrency out of your wallet to theirs, never share your private key with anyone you have got to keep it safe!\n\n\n![image 2.webp](https://cdn.steemitimages.com/DQmV4VgJtWukDR3mHVvu5xzg2Zgcg1VaYV2fUJMokgvCuFc/image%202.webp)\n\nWhat is a hardware wallet?\nA hardware wallet is a USB looking device which stores your “private keys” off of the internet so that no hacker can ever get to your private keys and steal your Cryptocurrency. \nWhat happens if a person loses their hardware wallet with the private keys on it or it gets stolen, has that person lost all of their Cryptocurrency?\nNot really, unfortunately that person would have to buy another hardware wallet obviously with no coins loaded on to it, but how can the ledger be restored back to its original state with all of the coins back on to it?\nA person restores their ledger back to its original state by inputting the 24 phrase words.\n\nWhat are these 24 phrase words? \nThey are random selected words such as “CAT”, “BOAT”, “RIVER”, “TREE”, “SKY”. These words are the backup words for your private key, in other words they “backup” and restore the ledger back to its original state with the original coins loaded back on to it again. Remember I said that your “private key” is basically proof of receipt that the coins belong to you. \n\nIs it safe to share your 24 phrase words with anyone?\nNO! The 24 phrase words are the back up to your private key. So, they are your private key. You don’t give out your private key and you don’t give out your 24 phrase words to anyone. It is your responsibility to make sure that these “phrase words” are written down on paper and stored in a safe place and kept off of the internet or any digital device.\nWhat is the safest thing to do with your Cryptocurrency?\nDepending on what coins you hold I know that the Ledger Nano S hold the major coins such as Bitcoin and Ethereum. Just simply store them on the Ledger Nano S and leave them there. Its all about time and patience, without being biased I firmly believe that Bitcoin and Ethereum will give you a huge return on your investment in maybe 10 years from now or less. \n\n\n![images 3.jpg](https://cdn.steemitimages.com/DQmfU4T2NSfhB53PZbqvGr1RCHYr8ujJTrZPhSPZ4aVnife/images%203.jpg)\n\n\nScams:\n\nRule number 1: If it sounds too good to be true then it probably is. In other words, if a person contacts you claiming to be able to mine you 10 bitcoin per day which will equal to $10,000 every day for the rest of your life then its rubbish and stay well away, simply block them on.\nIf a person contacts you claiming that their trading website can make you 10 bitcoin per day then ask them to provide evidence by them sending you their transaction ID. \n\nRule number 2: NEVER EVER give out your 12 phrase words to anyone! I will say that again, NEVER EVER GIVE OUT YOUR 12 PHRASE WORDS TO ANYONE! Your 12 phrase words are the same as your BSB and Account number for your bank account, they are the only back up for your private key. They are for your eyes only, no one should be asking for them, even if the asking person claims to be from a bank, the police, the government or from your own private wallet. NEVER EVER give out your 12 phrase words to anyone. Write them down on a bit of paper and store the paper in a safe place off line. Never store your 12 phrase words online or on any other electronic device.\n\nRule number 3: Trust no one online who you have never met in person before. So many scammers use fake Facebook profiles and identities. They will contact you with the typical rubbish of wanting to help you make millions of dollars. Ask yourself the question, why would they be wanting to help you become a millionaire, It's all a scam.\n\nRules number 4: Stay away from Binary Options. In some countries Binary Options are illegal. The most likely case is that you will be taken to a fake website called a “Phishing” and asked to input all of your personal details which will then be stolen. Then credit cards and bank loans can be taken out in your name and you will pick up the bill for them at the end.\n\nRule number 5: Always do your own research on a cryptocurrency before you invest into it, read through its white paper, what is the project trying to achieve. But remember that no one really knows what the market is going to do. If a person claims that a certain coin is going to be worth a small fortune in the future approach it with caution. Always remember that nobody knows what the market is going to do and you only ever invest what you can afford to lose. At the end of the day this is just gambling. You would never go to the casino and bet your entire house on \"Black\". Be responsible with your finances.\nGood luck trading.\nRob",

Because no one can ever take it away from you. “Warren Buffet”.  \n\nSo, starting off I must disclaim that I am not a financial advisor non do I claim to be one. If you are thinking of investing into a cryptocurrency you have to understand that investing is at your own financial risk. The same as investing into the stock market or buying an investment property is a financial risk. There is never any guarantee that any investment is going to be able to get you a good return on your investment (ROI) and even if I did know what the crypto market was going to do I most certainly would not be writing about it in a blog and announcing it to the whole world.   \n\n\n![coin 2.png](https://cdn.steemitimages.com/DQmSJ3TEjf6xuUHRdqeRzdfwh8Ecp17XLj5MUMuZVrUgAUf/coin%202.png)\n\n\nSo, let’s go back to the bare basics, what is a cryptocurrency?  \n\nA Cryptocurrency is a digital coin (much like an email) that is able to be sent from one computer to another computer using a platform called a “Blockchain” and the word “crypto” means that it uses very clever mathematics called “Cryptography” which is well beyond the scope of this blog, but trust me it works. These types of digital coins can be used as a currency to pay for items as they possess intrinsic value hence the word “Cryptocurrency”. \n\nHow does this Cryptocurrency move on the blockchain? \n\nThe same way as how does an email move from one computer to the other it moves electronically however a cryptocurrency moves using a Blockchain platform which is internet based using its clever mathematics (Cryptography). Each block of data is stored on a node and whenever your computer uses the Blockchain your computer becomes a node much like an internet server.  \n\nHow secure is the Blockchain?\n\nAs stated above any computer that uses the blockchain becomes a “node” so it becomes part of the blockchain its self. So if a hacker wanted to hack a blockchain the hacker would then have to basically hack into every single computer at the same time which is currently using the Blockchain. This method would be basically impossible even for the world’s fastest computer and to the best of my knowledge no blockchain has ever been hacked, expect for Ethereum Classic but that’s for a different blog. \n\nCan a quantum computer hack a Blockchain? \n\nQuantum computers have been seen as a Blockchains weakest link so theoretically yes, a quantum computer would be able to hack a blockchain due to its sheer computing power it would be able to hack every single node simultaneously and take down the whole system in theory. However, most computer scientists believe that a practical working quantum computer is still at least 20 years away so right now I would not consider a quantum to be any threat to a Blockchain.  \n\n\n![coin 3.jpg](https://cdn.steemitimages.com/DQmPfuh5FPwYecmkgyvuARivScb1mRQbuF5Dq1S4kQXFg8N/coin%203.jpg)\n\n\nWhat is Bitcoin? \n\nBitcoin was the first ever cryptocurrency launched 2009 by a computer programmer calling themselves “Satoshi Nakamoto”. Whether this person is a man, women or a group of people working together to this present day this person is “anonymous” with no true identity. Never the less this \"person\" published a white paper explaining the idea of using a Bitcoin which moved on a Blockchain and is credited with inventing the first every cryptocurrency (Bitcoin). \n\nWhy was Bitcoin invented? \n\nIt was invented in a direct response to the global financial crisis (GFC) of 2007. A time where world banks were basically lending out way too much money to their customers to buy houses. One of the main problems was that these loans were “interest only” loans meaning that the principal of the loans was not getting paid off at all, just the interest or the bear minimal payment to get by. \n\nThe idea was that at the time these houses were going up in value and it was thought that they would continue to keep going up and up in value. So it was in the banks best interest to keep on lending out money to people to buy more houses because the house prices kept on going up in value. However, when the time came for people to start paying back the principal of the loan as well as the interest people could not afford to pay both at the same time and so had no choice but to default on their home loans which then caused the price of these properties to crash as no body anymore were buying houses.  \n\nThe banks would then repossess the houses, then what does a bank do with a house which is depreciating in value? The banks basically needed their money back which was impossible because it had all been spent on a house which is now worth a lot less than the original loan to buy it with. Banks filed for bankruptcy and the governments came to their aid and bailed them out all using tax payers money at the expense of all of us who pay taxes. \n\nI my personal opinion it’s completely unfair what happened because the banks and the people who signed to take on the homes loans all had a responsibility to make sure that they could afford to pay back the loans, obviously they could not and so a houses crash occurred. So what was needed was a new currency that held its value.  \n\nWhat makes something valuable? \n\nWhenever governments fall under hard economic times they have a number of opinions available. One opinion is the ability to print more of their local currency. This currency is refereed to as \"fiat currency\" because it is not back up by anything its just paper at the end of the day. The number of Bitcoins will always be capped at 21 million meaning that there will only ever be 21 million bitcoins in circulation in the world ever. This cap of 21 million is what gives Bitcoin its value over time because obviously if the market was flooded with billions of Bitcoins and every one had Bitcoin in their wallets then the price of Bitcoin would collapse overnight there has to be a finite number of Bitcoin. \n\nHow and where do you buy Cryptocurrency? \n\nIts really simply, you go online and go to a cryptocurrency exchange. The exchange is a web page and there are many exchanges all over the world for you to choose from. Myself personally I use www.swyftx.com.au why? Because they are a local exchange for me and their fees are the lowest that I know in Australia. These exchanges sell many different types of cryptocurrencies it just depends on which one that you choose to invest your hard earn fiat currency into. \n\nWhat do you do once you have brought a cryptocurrency? \n\nThat’s completely up to up? Are you going to trade it quickly when it goes up in value or are you going to HODL (Hold on for dear life)? If you choose to HODL then I strongly suggest that you take the coins off of the exchange and send them to a cold storage hardware wallet as this is the safest way that I know of to keep your cryptocurrency safe. \n\n\n![ledger 1.jpg](https://cdn.steemitimages.com/DQmdBo9oQpfaV5sPZ8Brbbnyf1mFXJzFgnptrExm4xLbb7t/ledger%201.jpg)\n\n\n\nWhat is a hardware wallet?  \n\nA hardware wallet is a USB looking device which stores your “private keys”. What exactly are these private keys and why do they matter? Think of the private keys as a receipt or proof of purchase linked to your coins that you have brought. \n\nThink of this scenario, let’s say that you just brought a new car and you kept the receipt for the car. Then one night the car gets stolen and you have also lost the receipt for the car. If you went back to the car dealership and approached customers services, they will not be able to refund you for a new car because you don’t have the receipt (the proof of purchase). This scenario shows up just how important it is to keep your private keys safe. If you lose your private keys then you have lost all of your coins and as all cryptocurrency’s coins are decentralized there is no customer service help desk for you to call up and complaint to. It is 100% your responsibility to keep your private keys safe as it is the only way to prove that the coins belong to you. \n\nWhat happens if I lose my hardware wallet with the private keys on it or its been stolen? \n\nThe hardware wallet has your own personal pin code in order to open it up. So, the theft would have to know your pin number in order to open it. But even if the theft was able to crack your pin, they would then also have to know what types of coins that you have stored on the device then they would have to know what app pages you go to open them up using the ledger. \n\nUnfortunately, you will have to buy another hardware wallet, but how would you restore it back to its original state and get all of your coins back? Before you open up any new hardware wallet or any wallet for that matter you will be given a list of phrase words. What are these phrase words? They are random selected words such as “HOUSE”, “CAR”, “RIVER”, “TREE”. These words are the backup words for your private key. Remember I said that your “private key” is basically proof of receipt that the coins belong to you. Again, it is your responsibility to make sure that these “phrase words” are written down on paper and stored in a safe place and kept off of the internet. \n\n\n![mining 1.jpg](https://cdn.steemitimages.com/DQmWmJCNSBwAgeJM3YHoRDjD9A2JjiQwdjg9yFg2Sb11mA6/mining%201.jpg)\n\n\nWhat is proof of work (POW)\n\nPOW means that in order to gain a bitcoin or any other coin which allows POW a person would have to show “proof” of work that has been done. In this case it means computer mining which means getting many very fast computers and putting the all into a cool room where they run 24/7 completing complex mathematical tasks. Once a computer miner solves a task they are then rewarded by being given a bitcoin because they have shown proof of doing work, their reward is a Bitcoin. For a first timer into cryptocurrency i would definitely not recommend POW. To this present day a person would have to spend huge amounts of money on buying computer hardware and then running the computers 24/7 would mean that the ROI would not be worth it and building up huge electricity costs. \n\nWhat is proof of stake (POS)\n\nAs POW demands a very high cost of energy to achieve, but POS is when a person holds a certain coin. They are then “staking” that coin, in other words they hold on to that coin in their wallet. Much the same as when a person buys certain shares on the stock market they will then get paid out in the form of a dividend. Only the cryptocurrency that are already in the POS phrase will pay out the stake holder normally in another cryptocurrency such as “GAS” which also has fluctuating intrinsic value.   \n\nWhat can a person do with this GAS? \n\nWell if your smart with your finances you could use it to by more POS coins which in return will generate you more GAS. Much the same way as when a person leaves their money in a high interest savings account and lets the interest compound its self. Over time you will build more wealth. \n\n\n![scammer.jpg](https://cdn.steemitimages.com/DQmZ9zgG9scWgQwSTche4XhZ9iQpJSxqKCJwAyoovPXwJUr/scammer.jpg)\n\n\nCryptocurrency scams \nUnfortunately, where there are large sums of money there will always be scammers and the crypto world is full of scammers who just want to steal your money. If you choose to get involved in cryptocurrency you are going to be contacted at some point in time by a scammer. Most likely this scammer is going to contact you using the Facebook platform or WhatsApp.\n\nRule number 1: If it sounds too good to be true then it probably is. In other words, if a person contacts you claiming to be able to mine you 10 bitcoin per day which will equal to $10,000 every day for the rest of your life then its rubbish and stay well away, simply block them. \n\nRule number 2: NEVER ever give out your 12 phrase words to anyone. I will say that again, NEVER EVER give out your 12 phrase words to anyone. Your 12 phrase words are the same as your BSB and Account number for your bank account, they are the back up for your private key. They are for your eyes only. No one should be asking for them, even if the asking person claims to be from a bank, the police, the government or from your own private wallet. NEVER EVER give out your 12 phrase words to anyone. Write them down on a bit of paper and store the paper in a safe place off line. Never store your 12 phrase words online or on any other electronic device. \n\nRule number 3: Trust no one online who you have never met in person before. So many scammers use fake Facebook profiles and identities. They will contact you with the typical rubbish of wanting to help you make millions of dollars. Ask yourself the question, why would they be wanting to help you become a millionaire, It's all a scam.\n\nRules number 4: Stay away from Binary Options. In some countries Binary Options are illegal. The most likely case is that you will be taken to a fake website called a “Phishing” and asked to input all of your personal details which will then be stolen. Then credit cards and bank loans can be taken out in your name and you will pick up the bill for them at the end. \n\nRule number 5: Always do your own research on a cryptocurrency before you invest into it, read through its white paper, what is the project trying to achieve. But remember that no one really knows what the market is going to do. If a person claims that a certain coin is going to be worth a small fortune in the future approach it with caution. Always remember that nobody knows what the market is going to do and you only ever invest what you can afford to lose. At the end of the day this is just gambling. You would never go to the casino and bet your entire house on \"Black\". Be responsible with your finances. \nGood luck trading.\n\nRob",

      "body": "THE NEED FOR A SMART PHONE APPLICATION FOR THE PRE-HOSPITAL EMERGENCY CARE SETTING\n\nAbbreviations\nCode 1 \t-\tLights and sirens \nCode 2 \t-\tNormal road speed\nDAPP\t\t-\tDecentralised Digital Application \n\nAbstract\nA patient who has contacted an ambulance could greatly assist the treating paramedics by opening a digital application located on their smart phone. This application would contain the patient’s personal details and medical health records and would be able to be transferred over to the paramedics operational iPad. Gaining this digital data would avoid the treating paramedics having to go through the same repetitive questioning such as what medical history does the patient have, allergies, and current medications every time they encounter a new patient. The application would tell the paramedics what hospital the patient normally attends and what medical conditions that hospital has diagnosed the patient with. The application would be most effective when used in conjunction with patients suffering from chronic health conditions. But would probably be of limited benefit to those with acute life-threatening injuries who are normally healthy and have no medical history. Queensland has an aging population and for many years now has seen a rise from interstate retirees coming into the state. These retirees bring with them more age-related diseases such as cardiovascular disease, hypertension, osteoporosis arthritis, dementia and many more. (Elizabeth Tilley, The Courier-Mail 2017). Currently when a paramedic is contacted to treat these patients for non-life threatening chronic conditions the paramedic is required to go through a series of repetitive questioning in order to gain the relevant medical history. It is sometime unreasonable for an elderly patient to remember all of their medical conditions or for them to fully understand what their doctor has diagnosed them with or why they have been prescribed a certain medication. Like any digit system the risk of personnel information being hacked or compromised is high, therefore I propose that this medical application is run on a blockchain platform making it a DAPP running on an Ethereum type platform or whichever platform best suits the DAPP to run on and is able to scale the data in a reasonable time frame. \nIntroduction\n\n\nThis paper has been written with the aim to highly light the possible roles that a medical smart phone application could play in assisting a paramedic in treating a patient in the pre-hospital care setting. Some of this information contained comes from my own personal on road experiences of being a paramedic for the past 10 years. At the end of 2019 it was estimated that twenty million Australians owned a mobile smart phone with that figure continuing to rise every year from now. (Number of mobile phone users in Australia from 2011 to 2019). By 2030 the 5G phone network will have become firmly embedded with our infrastructure, all electronic devices within our homes will be connected to the internet, our cars, TV, microwave, fridges and even light bulbs will all be connected and the so called “internet of things” (IoT) will have arrived. (Our predictions for 2020 and the decade beyond). The IoT will clearly open up new opportunities for private companies and government services. However, we don’t have to wait until the year 2030 as the technology that I’m proposing is already here. Even the lowest end model of smart phone is capable of running applications (apps) on either the Apple or Android operating systems. The major hurdle in the way that I can see is the problem of securing patient’s private information and therefore ensuring patient confidentiality. If a criminal was able to steal or hack into a patient’s smart phone then they would have complete access to all of that patient’s personal and medical records. Although still an evolving technology Blockchain could solve these security problems by making a system where data is transferred from one computer to the other completely independent from a third party. \n\n\nBlockchain technology \nBitcoin was the first ever cryptocurrency launched 2009. It acted as a proof of concept that one Bitcoin can be transferred on blockchain technology to computers anywhere in the world and to the best of my knowledge the bitcoin blockchain has never been hacked or failed in anyway. Other Blockchain projects such as Ethereum aim to widen the capabilities of Bitcoins blockchain by effectively allowing much larger data volumes to be sent over the blockchain. If a medical application is run on an Ethereum type platform it will become a Decentralised Digital Application (DAPP) therefore making it unhackable. When the paramedic wants to access all of the data on the DAPP the patient will have to simply scan a QR bar code located on the paramedics iPad using their own smart phone. This QR code will then show up on the patient’s smart phone as a public key address. The patient then sends all of their medical records to that same public key address which matches the public key as the paramedics iPad and so the transfer of the patient’s medical records over the Blockchain network is completed much the same way how a Bitcoin is sent from computer A to computer B with out any data compromised. \n \n\n![](https://cdn.steemitimages.com/DQmUWuy9z4hfitcSXZJAykCxX56w3U6bXTLEyqksZ2HgUcC/image.png)\n\nExample of a QR bar code which would result in the public key address of where to send the medical records to). \n\n\nBelow is a very basic example of the type of information that the paramedic would need to access when treating a patient for the first time.      \nBasic example of a smart phone application\nPatients Personal Details:\nName: James, Peter, Smith \nDate of Birth: 09/12/1942 \nAddress: Brisbane, Queensland. \nPast Medical History: \nAcute Myocardial Infarction in 2017\nCoronary artery bypass in 2017 at the Logan Hospital. \nCholecystectomy in 2010 at the Logan Hospital \nOsteoporosis diagnosed in 2012 by Doctor White. \nHypercholesterolaemia diagnosed in 2012 by Doctor White. \n\nAllergies to medications:\nPenicillin (Warning penicillin causes an anaphylaxis reaction) \nMedications Taken:\nPanadol Osteo (Analgesia pain relief) \nLipitor \t(For high cholesterol)\nAspirin\t(To stop the blood from forming clots)\nWarfarin\t(To stop the blood from forming clots)\n\nNumber of contacted ambulances and why: \n01/01/2017: Chest pains, paramedic crew administered 300mg of Aspirin, 0.4 mcg GTN, 5mg of Fentanyl. Patient transported to the Logan hospital. Logan hospital diagnosed the patient with an Acute Myocardial Infarction. Patient was admitted and a coronary artery bypass surgery was completed on 02/01/2017. Patient was discharged on the 03/01/2020 with a prescription of lifelong aspirin and warfarin. \n01/01/2018: Mechanical fall from standing height to the fall. Paramedic crew lift assisted the patient to their feet. Transport refused by the patient, no treatment from the paramedic crew, no diagnosis made. \n01/01/2020: Chest pains, paramedic crew administered 300mg of Aspirin, 0.4 mcg GTN, 5mg of Fentanyl. Patient transported to the Logan hospital. Logan hospital diagnosed the patient with unstable angina. Patient is referred to a cardiologist for and awaiting an echocardiogram on the 01/02/2020. \nThis section is for the patient’s own information which allows them to understand and take an interest into their own health. \n\nWhat are your medical conditions? \n•\tYou suffered an Acute Myocardial Infarction in 2017 or more commonly known as a heart attack. This means that the muscle around your heart was not provided with enough blood supply which is rich in oxygen and is now unfortunately a lot weaker it originally was. \n•\tAfter the acute myocardial infarction, you had an operation called a coronary artery bypass in 2017 at the Logan hospital. This means that the Cardiologist Doctor took a vein from your right leg and placed it into your heart to bypass the blood supply so that this blood supply can still continue to perfuse the muscle around your heart. \n•\tOn 03/01/2017 you were discharged from the Logan Hospital and prescription of lifelong aspirin and warfarin. This is to stop your blood from clotting so that a clot does not occlude a blood vessel in your brain causing a stroke.    \nPatients normal GP:\nDoctor David White, located at Brisbane medical centre, contact number: 12345.\n\nBody of review\nThe strain on the public health system is becoming more apparent every year despite large amounts of government spending. My personal opinion is that the Queensland Ambulance Service should be utilising already existing technologies to improve efficiencies which would cut costs. Governments sectors should always be collecting data on their populations in order to better understand their current needs and using this data to make services more efficient. The medical phone application that I’m proposing is aimed at people within Queensland who suffer from chronic health problems and the elderly who are continuously contacting ambulances. The transfer of medical data would greatly reduce the time that a paramedic has to stay on scene with the patient and would assist the paramedic and hospital to build up a better treatment plan for the patient. For example, if a patient contacts an ambulance because they have pain in their right shoulder once the paramedic has access to that patient’s medical records via the app they will be able to see that the patient was diagnosed with chronic right sided bursitis and therefore an AMI is highly unlikely. Once a person has been discharged from a hospital a medical receptionist will update their application either by them manually in putting the new data in to the patient’s phone or the data could be blue toothed across using the hospital system. \n\nCurrently in Queensland when a person wants to contact an emergency service ambulance, they are required to dial 000. The call will then be connected to a comms operator who will start to go through a series of questions with the aim of trying to assistant how serious the medical problem is and what code should an ambulance be sent to the calling patient. During the questioning there are certain key words that the calling patient must answer, and these key words will determine what code the ambulance is sent either code 2 which is normal road speed obeying all traffic rules or code 1 which is lights and sirens with the ability to proceed safely through red lights.  \nWhen the paramedics are on route to the incident, the crew are able to gain limited updates about the calling patient such as their name, age and what symptoms they currently are experiencing.  \nOnce the paramedics are on scene and have located the patient the treating paramedic will start to complete their own series of questions. All paramedics will have their own questioning methods but normally all basic questioning will start such as: \n\nParamedic Basic Questioning: \n•\tWhy did you contact an ambulance today and what symptoms are you currently experiencing today? \n•\tWhen did these symptoms that your experiencing start?\n•\tHave you seeked an appointment with your local GP about these symptoms?\n•\tIf you have any pain symptoms have you taken any analgesia to relieve the pain?\nThese basic questions should be enough for the paramedic to determine whether these symptoms are chronic or acute life threatening.\nDiscussion \nUnfortunately, the vast majority of ambulance call outs are not in my own personal opinion classed as non-emergencies (non - emergencies means that the patient’s life is not presently not in danger). The vast majority are for chronic health problems such as where a patient has already been assessed by their local GP or is already known by a hospital.  \nUsing my own personal experiences, I have come to the conclusion that the general public’s knowledge on the most basic of medical subjects and conditions is extremely poor. I can only narrow this down reason down to 3 factors. \n\n1.\tDoctors are not clearly explaining to their patients what their medical conditions are in a way in which that the patient fully understands and what type of medical condition that they have being diagnosed with and why. Doctors need to spend more time communicating with their patients so that they fully understand their medical conditions however this is clearly going to take extra time and hospital waiting times are already extensive.   \n\n2.\tThe patient will still not understand what they have been diagnosed with even though it has been explained to them. This could be because the patient has a language barrier, the patient is elderly and suffers from confusion, comes from a low socioeconomic region or has a low education. \n\n3.\tA small percentage of patients are not interested in their own health or are not in touch with their own bodies. People are in denial and do not want to hear what a Doctor has diagnosed them with. \n\n\nConclusion\nI believe that this DAPP should be made so basic and simple so that any persons can use it. It must be also clearly explained what type of medical conditions the patient is suffering either using clear animations or pictures. This DAPP would have limited uses for a patient’s with acute life threatening injuries. This is because a paramedic has very limited time on scene when treating a dying patient. The paramedic will simply collect the most basic information then transport that patient to the nearest hospital code 1.  \nBlockchain technology is constantly evolving and is not yet used by the main stream public. However as stated above Bitcoin basically proved that it can be sent from a computer to another and it will never get compromised or fail to the best of my knowledge. Other projects such as Ethereum are working to open up Blockchain technology to send much larger amounts of data faster and there are many other competitors to Ethereum all working on their own blockchains.   \nPatient confidentiality is always taken very seriously in the medical industry, develops of the DAPP will have to ensure that the DAPP has added security features such as passwords, finger recognition or retina eye scan.       \nScaling is the ability for any blockchain to transfer data from computer A to computer B. At this present time the Ethereum blockchain does have problems with its scaling abilities however this has been recognised as one of its key problems and a huge amount of work is currently being conducted in order to reduce the scaling problems. It must also be noted that this DAPP won’t be constricted to just the Ethereum blockchain, it will be able to run on any blockchain which best services the DAPP because it would be very inconvenient and defeat the purpose for a paramedic to have to wait on scene with a patient for 30 min because it took that long for the transfer of the patients data to the paramedics iPad.   \nThe technology that I’m suggesting is already here now however it is still in its infancy and like all new technology cost will also be a huge factor. But like all new technologies it will always be expensive in the beginning but should gradually fall.   \n\nReference List\nElizabeth Tilley, The Courier-Mail (2017) The most popular Queensland destinations to retire.
