      "title": "Behind the frenzied issuance of USDT: why is it not rising?",
      "body": "### Content\nThe issuance of USDT has surged in recent months. As of the deadline of April 16, 2020, the current total USDT is more than 6.9 billion U.S. dollars. It was only more than 2 billion U.S. dollars a year ago, and it has increased by 3 in about a year. Times more. Especially in the last two months, there has been a skyrocketing. It was only US$5 billion in the middle of last month, and it was close to US$7 billion in just one month.\n\n\n![image.png](https://cdn.steemitimages.com/DQmZA9rSKKkoAMSD27py2H6kfZsMVbcJzkvA648Ss2efb7a/image.png)\n\n(Source: http://Tether.io)\n\n\n\nJudging from the current development trend, USDT has basically achieved the conformity of products and market demand with certainty. So, why has USDT been issued frantically recently? What is the reason behind it? There are also many readers of Blue Fox Notes asking if this means that over-the-counter funds are entering the cryptocurrency market, and will it cause the price of the currency to rise? According to historical experience, large-scale USDT issuance may cause the price of the currency to rise, but now it seems that the price of the currency is not moving, or even weak. why is that? Just from the observation of Blue Fox's notes, unlike the situation two years ago, the situation is more complicated now. How to understand this phenomenon? The reason that drives USDT's frenzied issuance is that it finds a high degree of conformity between products and market demand. According to the current trend, the market value of USDT will soon become the top three in the entire crypto market. It is no surprise if it can keep pace with Bitcoin and Ethereum in the future. .\n\n### Hedging demand\nThe global outbreak of COVID-19 has not only caused the stock market to fall, but most importantly, it has done unprecedented damage to economic fundamentals. It has caused an unprecedented number of blowouts in the U.S. stock market, leading to an unprecedented wave of unemployment in the United States, and most industries have been greatly impacted.\nIn this context, the cryptocurrency field, which has always been an independent market, cannot stand alone. Due to the shortage of liquidity, Bitcoin and cryptocurrencies also plummeted, leading to black swan incidents in the crypto field. In an environment of increasing uncertainty, people have a great need for hedging. However, hedging cannot be achieved through volatile Bitcoin and cryptocurrencies. In this case, many people prefer to hold stablecoins to avoid risks. This includes converting cryptocurrencies into stable currencies, which can avoid volatility risks. In addition to USDT, stablecoins such as USDC and BUSD have also increased significantly. \nIn order to cope with the extreme volatility of cryptocurrencies, many users exchange their cryptocurrencies for stablecoins, which has led to an increase in the demand for stablecoins. As shown in the figure below, there are more than 800 million US dollars of stablecoins lying quietly on the exchange, most of which are USDT. However, the stablecoins of these users are more waiting for opportunities. Stable coins are only a temporary haven.\n\n\n![image.png](https://cdn.steemitimages.com/DQmZkEA6VTeXigzW6jqTF8rJXvN4Gz9SJxt5NPinxwhkSsR/image.png)\n\n(Source: TokenAnalyst)\n\n### Value transfer demand\nCryptocurrencies are inherently highly liquid, but due to the excessive volatility of cryptocurrencies such as Bitcoin, they are temporarily not suitable for value storage and more suitable for speculation. The stable currency issued based on the blockchain not only has the characteristics of fast transfer of encrypted currency, but also has stability. At the current stage, this makes stablecoins more suitable than Bitcoin as a medium for value storage and circulation. \nSome OTC users sell cryptocurrencies and convert them into stable currencies such as USDT, and store them in encrypted accounts instead of converting their funds into legal currencies such as U.S. dollars. In other words, these funds do not enter the traditional legal currency account system. Cryptocurrency accounts are flexible and user controllable. In order to meet the needs of its customers, OTC counters have also generated demand for USDT. The actual scenes also include international remittances and import and export transactions. \nThe demand for value transfer, coupled with the dual role of hedging demand, has led to a huge increase in the demand for stablecoins. In recent times, the amount of value transfer on Ethereum has been close to that on Bitcoin, and in the value transfer amount of Ethereum, more than 80% of the value transfer is the value transfer of stable currency. From this data, we can also understand why the demand for USDT has soared.",

      "body": "### Content\nThe encryption field has been conducting various innovative cutting-edge experiments, including encrypted games and encrypted virtual reality. These attempts are gradually showing results, thanks to many aspects, and one of the very key points is that the encryption economy drives the self-growth of the ecology.\n\n　　What is the encryption economy driver? Combine the original existing purely centralized product form with encryption technology and token mechanism to produce a brand new system. And this new system makes the ecology itself a sustainable possibility. These projects were initiated by the founding team, but ultimately, it depends on the participants in the community. It turns entrepreneurial projects into community projects.\n\n　　 At present, there are more and more game projects in the encryption field, and transactions about NFT are becoming more and more frequent, and some NFT products even have a transaction price of more than 100,000 US dollars. Among them, Decentraland, Axie Infinity, etc. are more typical, with a certain scale of NFT transaction volume every day. These game projects are gradually growing out of a completely different gameplay and development logic from traditional games.\n\n![image.png](https://cdn.steemitimages.com/DQmTiQ8GaJnTgvvSAgEciYoujfdUNqpT2VW1rtx71dNUgKw/image.png)\n\nWhile OVR is an AR platform, it also tries to combine encryption technology and encryption economy to shape a new open sustainability. To understand the world of OVR, we can simply compare it to the world of Decentraland, but one is an augmented reality platform and the other is a virtual reality platform.\n\n### The world of OVR: a new world where reality and virtuality intersect\n\nAR English is Augmented Reality, and Chinese is translated as Augmented Reality. It is a technology that \"seamlessly\" integrates real world information and virtual world information. It can be displayed on the screen through various hardware devices (such as mobile phones and smart glasses). The virtual world is superimposed on the real world to create a new experience that intersects reality and virtuality.\n\n![image.png](https://cdn.steemitimages.com/DQmesV1tCJNFe9Z5g1efAmnDbj6EsTN5Dc76YBoVGC5NBo2/image.png)\n\nIn the OVR world, it divides the earth in reality into 1,660,954,464,112 hexagons. Each hexagon represents the size of 300 square meters. These hexagons make up the land in the OVR world.\n\n　　 Because of GPS and computer vision technology, OVR applications can provide users with an AR experience combined with geographic location. The land where the real world and the virtual world intersect is unique. In order to mark the location of these hexagonal lands, OVR uses three English words to mark the model. Through three words, the OVR land can be located, such as good.in.world.\n\n　　 This is different from the virtual land on Dencentraland. OVR has the foundation of the real world. It embeds virtual objects in the real world to produce a new interlaced experience. OVR technology can superimpose various media content into the real world, such as video, voice, 3D images, etc., which is equivalent to superimposing a new dimension in the real world, and this dimension creates a unique media and social space.\n\n　　With such a basic concept, what can people do on OVR? Users can buy land in the OVR world, and the ownership of OVR land really belongs to the owner, because it is represented by NFT, which is a non-fungible non-homogeneous token. Users only need to hold the private key. You can own it. This is significantly different from traditional augmented reality projects, because in traditional AR, digital assets such as land and virtual items are stored on the central server of the project party. If the project is closed, these virtual land and items cannot be technically owned. To the owner.\n\n　　 What can I use for the OVR land when the user purchases it? You can decide to build the AR experience you want on its OVR land, and you can decide what content to display in the geographic location you own. For example, you can decide to display brand interactive advertising in the central business district of the city, you can use it to earn revenue; you can build AR interactive games on your own OVR land; you can build an AR store on your own OVR land to help users choose Make decisions so that users can browse and shop through AR even after the door is closed; you can build an AR museum on your own OVR land...\n\n　　 If you are a creative digital builder, you can help OVR landowners build various AR content, and benefit from it. Whether the future OVR world is attractive or not requires a large number of virtual digital layer builders to create various new experiences.\n\n　　As an ordinary user, he can have various AR experiences in the OVR world. If he is an advertiser, he can publish AR advertisements and brand marketing in the OVR world...\n\n### Possibility of AR platform\n\nThe development of computing hardware has promoted the development of new media and new social. From desktop computers to smart phones and smart glasses, terminal upgrades have promoted the evolution of countless media and social applications, from the original yahoo to twitter and facebook, and then to the current Instagram And Tiktok...\n\n　　 With the development of smart devices (mobile phones and glasses), AR and VR technologies have the opportunity to promote the new evolution of media and social in the future. According to IDC's data, the AR market value reached 27 billion U.S. dollars in 2018, with a compound annual growth rate of about 70%.\n\n　　 Just as we did not imagine that live video broadcasting is so developed and widely used today, it may be difficult to imagine the development of VR and AR in the future.\n\n\n![image.png](https://cdn.steemitimages.com/DQmePJnRowozxrH7PR9EDikYwP1uBmrdwE1FHsQA44QCc92/image.png)\nThe AR platform is still at a very early stage. The evolution of this field, along with the iteration of technology and the maturity of the encryption economic model, may bring us unexpected development.\n\n### The possibility of business ecology in the OVR world\n\n　　OVR world is essentially a digital layer built on the basis of the real world. After a user purchases land in the OVR world, he can create an AR experience and create a variety of virtual items. From the beginning of \"Pokemon Go\", we can feel this.\n\n　　From the perspective of commercial applications, AR will bring a new experience to our lives and learning. It is possible to develop a new business ecology in fields such as games, education, commerce, and media advertising.\n\n　　 For example, through the OVR world, various digital items such as Axie can be brought into the real world and interact in the real world, which will create a more interesting experience.\n\n![image.png](https://cdn.steemitimages.com/DQmVjougpj8PSx9Z6pHJEsCFQaLiuXqXPgFf1eyziWDzbno/image.png)",

      "body": "### Content\nAlthough it feels like a long time, but in fact, Basis has only been online for more than a month, and it is still a new project. Basis is the successor of the original basecoin model. After this period of practice, how does the founder of basis view the Basis project? This is critical to our understanding of the future direction of Basis. The following is summarized based on the community statement of Morty, one of the founders of Basis.\n\nBasis's three priorities\n\n* Dynamic coin threshold\n\nAccording to Basis's community proposal BIP-5, Basis will implement a dynamic minting threshold, and the expected initial minting price will drop from the current 1.05 to 1.037, which means that the future BAC TWAP price will exceed 1.037 (instead of the current 1.05) After that, BAC will be generated to motivate holders of BAB and BAS.\n\n\n![image.png](https://cdn.steemitimages.com/DQmQwrRPPbGQbPxAk9pvDqjckRVuU8eDpJ3HEbwwLWzGXmV/image.png)\n\n* Integrated DeFi protocol\n\nFor algorithmic stablecoins, it does not have any collateral. At present, it is basically a speculative game. This is unsustainable. If you want to survive, you must find more application scenarios. The more protocols that integrate them, the more effective the algorithm is. The more demand for stablecoins, the more secure.\n\nAt present, Basis is planning to integrate with some protocols, and some have been integrated, including pickle, harvest, cream, sushi, Curve, Secret, etc.\n\n![image.png](https://cdn.steemitimages.com/DQmPDzraCRqSfdFRB8EHhey7W1222NDMjF8syNv1nDE8fxn/image.png)\n\nHowever, these agreements are far from enough. More agreements should be integrated. Of course, it has only been born a month, and it will take some time. To this end, the Basis team even plans to hire a person in charge of protocol integration.\n\n* Set the upper limit of BAB circulation\n\nThe price of BAC is determined based on one-hour TWAP. If it is less than $1, BAB can be generated, and the discount depends on the one-hour TWAP price. However, there is a problem here. If the TWAP price is 0.9DAI, BAB can be mined by destroying 0.9BAC. At the same time, users can use 0.8DAI to purchase BAC (because of the price fluctuation of 1TWAP) to participate in the destruction, which is actually 1BAB=0.8DAI .\n\nThe issuance of BAB debt without a ceiling may lead to excessive BAB issuance. The spam of BAB will be detrimental to the development of the system. First of all, it will be detrimental to BAS holders because the BAC generated by minting in the future will first be used to repay debts. A large amount of debt means that BAS holders need to wait a long time to get the reward. Secondly, a large number of sudden additions of BAB will also affect the demand for buying new debt, because it also means longer waiting time for BAB redemption. Finally, the spam of BAB will also lead to excessive deflation of BAC, which is also not conducive to the stability of BAC itself and deviates from the goal of BAC as an algorithmic stable currency.\n\nFor this problem, the team's solution is to set the maximum BAB issuance limit: ($1-1hTWAP)*(Circ $BAC), 1hTWAP is the BAC price of 1 hour TWAP, and Circ $BAC is the circulating supply of BAC. For example, as of the writing of Blue Fox Notes, its 1hTWAP BAC is $0.75, and the circulating supply is 61,419,303, so the current upper limit of the BAB that can be generated is 15,354825.75. This upper limit lasts for 1 hour, and the upper limit is recalculated after one hour.\n\nWon't take a hybrid road\n\nIn the current algorithmic stability model, there are hybrid algorithmic stablecoins, such as the partially mortgaged FRAX model, and the Basis team clearly stated that it will not consider a hybrid model. The Basis team believes that a purely algorithmic model can also achieve its goals.\n\nIt is not advisable to reward BAB holders through part of the funds in the reserve treasury\n\nSome people propose to use part of the treasury's funds to purchase BTC or ETH as reserve funds when BAC issuance, and subsequently use it to incentivize BAB holders (if BAC is lower than the anchor price for a long time).\n\nBut Morty, the founder of Basis, does not support this approach. Morty believes that this approach may encourage bond buyers to manipulate BAC prices for profit. In this matter, the Basis team has its own clear idea.\n\nIt is not supported to distribute 20% of the additional BAC bonus to BAB holders\n\nSomeone proposed to give 20% of the additional BAC bonus to BAB holders to incentivize people to hold BAB and restore price anchoring as soon as possible. The Basis team believes that BAB and BAS holders have different risk/return preferences. What BAB more satisfies is the demand of fixed rate of return, and obtains premium through redemption. Holding BAS means holding a long position in the entire basis agreement. Therefore, the two need to be clearly distinguished.\n\nAnchored with a basket of currencies\n\nCurrently BAC anchors DAI, but in the future, for the resilience of the system, it will consider anchoring a basket of currencies.\n\nDon't worry about the impact of mining on the agreement\n\nSome people are worried that if pickle is integrated, the price of bas will drop. The founder Morty is not worried about selling pressure from mining. Because ultimately, if mining is widely adopted, the price of BAC will rise, and the price of BAS will form an equilibrium. At the same time, this will also attract more users to participate in the Basis ecosystem, especially ordinary mining users. From the current point of view, mining does not bring big risks to the agreement itself, but will bring greater liquidity and enhance the resilience of the system. At the same time, there are also some long-term believers who are willing to take greater risks, accumulate more BAS, and try to get benefits from the long-term development of the Basis agreement.\n\nPlans to launch Basis Swap\n\nThe Basis team has plans to add more liquidity pools. The team believes that only relying on BAC/DAI on Uniswap cannot achieve the desired results, and its price curve cannot be as effective as expected. At present, it is trying to pass the governance vote of Curve. If it is reached, the BAC/3Pool liquidity pool will be provided on Curve.\n\nIn addition, there are plans to increase the liquidity pools of BAC/wBTC and BAC/ETH, and this part will be implemented in the mid-term. In Basis's mid-term plan, it proposed to build its own Basis Swap, which is its own AMM liquidity pool, to build more practical application scenarios for BAC, thereby increasing the resilience of the system.\n\nRewards based on BAS lock time\n\nIn the future, it will be planned to adopt the veBAS model of reward locking, similar to the veCRV model, but this will have to wait until the launch of Basis Swap. The launch of this plan is conducive to locking in more BAS, and it can also give more reasonable returns to holders who have been locked in for a longer time.\n\nWorking with economists to improve Basis's token economic mechanism\n\nAccording to Morty, one of the founders of Basis, the team is currently discussing with some economists to continuously improve its token economic mechanism. This also shows that the algorithmic stablecoin is just a newborn and a brand-new thing in human history. Its growth still requires a lot of effort, and it is not something that can be accomplished overnight. It requires continuous iterative growth in practice. At present, Basis has not experienced a complete cycle, and it needs more time to increase people's confidence in it and the resilience of its system.\n\nWill consider other public chains\n\nIn addition to Ethereum, Basis will also consider issuing and launching on other networks. For example, by integrating with Secret Network, BAC will be circulated on the Cosmos-SDK chain. The advantage is that the transaction cost is low and the speed is fast.\n\nNew UI\n\nA new UI style will be released in the near future. In addition to supporting the Metamask wallet, it will also support some other wallets. It shouldn't take too long to see the real face. The new version is said to be available in Chinese and other languages.\n\n\n![image.png](https://cdn.steemitimages.com/DQmSfeQeNAybX95mBUNjqFW5xUG3MwqqAChX6MyGpKXjEJx/image.png)",

Pain points of traditional authentication\n\nThe process is complicated: Taking copyright protection as an example, the existing authentication method requires long registration time and high cost.\n\nInsufficient credibility: Taking legal deposits as an example, individuals or centralized institutions may tamper with data, and credibility is difficult to guarantee.\n\n2. Blockchain + certification\n\nSimplified process: After the blockchain is applied to the attestation certificate, it is very convenient for both registration and inquiries, and there is no need to travel between various departments.\n\nSafe and reliable: The decentralized storage of the blockchain ensures that no organization can tamper with data arbitrarily.\n\n3. Application case\n\nThe application of blockchain in the field of authentication certification includes copyright protection, legal deposit certification, etc. The following takes copyright protection as an example to briefly explain how blockchain realizes copyright registration and inquiry.\n\n(1) Electronic ID card: The copyright information such as \"applicant + release time + release content\" is encrypted and uploaded. The copyright information is used for the unique blockchain ID, which is quite an electronic ID card.\n\n(2) Time stamp protection: When the copyright information is stored, time stamp information is added. If the right is the same, it can be used to prove the order.\n\n(3) Reliability assurance: The decentralized storage, private key signature, and non-tampering characteristics of the blockchain enhance the reliability of authentication information.\n\nIn August 2016, several institutions including Onchain, Microsoft (China), and Falun Dafa University established the electronic deposit evidence blockchain alliance \"Fachain\" in Beijing.\n\nIn December 2017, the arbitration alliance chain jointly launched by WeBank, the Arbitration Commission (Guangzhou Arbitration Commission), and Hangzhou Yibi Technology Co., Ltd. was used to deposit evidence in judicial scenarios; in March 2018, Guangzhou’s first \"arbitration chain\" \"The verdict is out.",
