I have been involved in several projects that have shaped my career and improved my skills. As researcher in Computer Science at the University of Leuven I developed novel hypervisor-based approaches to computer security, some of which became core technology at VMWare. [Download](https://lirias.kuleuven.be/bitstream/123456789/413219/1/phd+dissertation.pdf) my dissertation\n\nAs member of the Statistical Genetics Unit at the Department of Electrical Engineering and Computer Science of the University of Liège, I have been searching for solutions to integrate heterogeneous data (OMICS) within common analytics framework, assembling networks and merging clinical and genetic data together to make predictions about the risk of diseases for patients in a pre-symptomatic fashion.\n\nI have been research data scientist at the Gasthuisberg Research Hospital located in Leuven, Belgium - one of the largest research hospitals in Europe - and member of the Non-Invasive-Prenatal-Testing [NIPT](https://en.wikipedia.org/wiki/Prenatal_diagnosis) research group.\n\nI have been member of the Advanced Analytics Team of Johnson & Johnson where I designed and implemented the most accurate predictive models for disease interception and drug recommendation. In addition, I have adviced a number of big data technologies and strategies that turned out to be essential to the organization on a global scale.\n\nI am currently Chief Data Officer at Abe.ai, designing AI solutions that help people managing their assets and founder of [fitchain.io](http://fitchain.io) a decentralised machine learning factory\n\n## Other stuff\nI am currently based in Belgium, traveling extensively across Europe and USA. During my spare time I enjoy (a lot) reading books and (even more) long distance running. When I feel inspired and get the time I enjoy photography.\n\n\n## I am who I say I am\nSecurity is as important as confidentiality and privacy.

      "body": "In the aftermath of the explosion of cryptocurrency Ethereum (from $65 to $100, then $150 and higher), I feel the urge of sharing my thoughts and trying to make sense of what is happening.\n\nDISCLAIMER\nDespite the amount of hours spent researching, programming and evaluating the blockchain world, this post is my personal opinion and should not be considered as a suggestion to buy/sell cryptocurrencies nor as a financial analysis.\nIt is undeniable that Bitcoin has dominated the world of cryptocurrencies since 2013, when it exploded after reaching 100$ to skyrocket towards 1000$ in a matter of days. \nTurns out that this might happen again. Unfortunately.\n\nThis would be unfortunate due to the fact that in Ethereum there are all the requirements to skyrocket way higher than 1000$. In this post, I will explain why Ethereum is more valuable than the concept of fiat currency.\nI will also explain why the traditional way of thinking about blockchain, technology, and the Internet is obsolete. Defining Ethereum as another cryptocurrency can be misleading. Ethereum can change everything.\n\nEthereum is a platform that can execute code on the blockchain, without any downtime, fraud, or outside interference. The essence of the Ethereum platform is embedded in the concept of Smart Contract, the real code that is executed in a decentralised fashion.\n\nTo make a comparison with its old cousin Bitcoin, the simple capability of writing a payment transaction such as Alice pays Bob 1 BTC can be easily extended to the more complicated transaction Alice pays Bob 1 BTC if Bob’s wallet is 10% lower than yesterday. In Bitcoin, a certain amount can get payed or transferred if there is enough balance in the source wallet. With Ethereum many other conditions can be applied, making the application richer and more useful for an enormous amount of real-world scenarios.\nAs a matter of fact, the possibility to encode conditions together with code execution (on the blockchain) is something that everybody was looking for since Bitcoin was created.\n\nTo better understand this concept, let me quickly explain how the CPU works. In Computer Science there is a limited set of instructions that is recurrent in practically any program that one can execute on a CPU (Central Processing Unit). This particular set of instructions gives a system\n\nthe ability to create, read and write variables (of any type, eg. char, string, arrays, numeric, int, float, etc.)\nthe ability to simulate moving the read/write head\nthe ability to simulate a finite state machine (FSM)\na HALT state\nIn two words, Turing Completeness, the property of a system to execute any program (also called computationally universal system). Such theory was invented by Alan Turing under the name of Universal Virtual Machine.\n\nHaving said that it turns out that Ethereum is a Turing Complete Platform. Well, almost. It would be fully Turing complete only if a program could execute for a limited but indefinite amount of time — which is currently not possible because of energy constraints. Basically, every instruction requires an amount of gas to execute on the Ethereum platform. This gas is usually payed by the owner of the code for his software to be executed. Needless to say that an application out of gas will stop working. \nThis energy/gas constraint is what makes Ethereum sustainable. To the purists, it makes Ethereum not fully Turing complete. However, the gas mechanism is essential to guarantee incentive and the entire functioning of the Ethereum Virtual Machine in a decentralised yet secure way on the blockchain. In addition to that, the memory depth of the Ethereum Virtual Machine is limited for security reasons.\n\nSmart contracts — the name that has been given to the the gas-burning instructions - can be written in very user friendly languages such as Solidity and Serpent. With such languages people have the ability to do all the things they already do in languages like Javascript or Python, such as loops, branching statements, local storage, use of variables, computations. Basically, anything a non trivial program requires.\n\nAs a matter of fact the Turing complete Ethereum Virtual Machine can execute any program, with the same sophisticated logic of traditional computing. The only difference is that execution occurs… on the blockchain. This opens the door to a plethora of new possibilities the Bitcoin community has been dreaming about for years. In comparison the Bitcoin platform looks very limited. And it really is much more limited with respect to the infinite possibilities offered by the Ethereum platform.\n\nWhat can be run on Ethereum?\nTuring completeness immediately translates into anything. For the sake of clarifying what anything means let me roll down some possibilities.\n\nGiven that the code of the smart contract needs to be replayed from the genesis block, it must be deterministic. This means that there cannot be any random value during execution. A general application can deal with random values of course. While being a limitation for Ethereum, the Turing completeness still allows complex logic to be handled.\n\nGenerally speaking most of the applications we are using today can have its distributed equivalent, also called Dapp.\n\nGuess what an application called WhatsDapp might do? In such a Dapp a message from Alice to Bob would just duplicate among many individual computers, until destination, Bob’s computer. All the computers between Alice and Bob are basically making the transfer possible, allocating their resources, network, memory, computing power, in exchange for money or Ether, the currency of the Ethereum Platform. Needless to say, end-to-end encryption would be possible too.\n\nWhen complex logic is possible, one can write a Dapp to manage, exchange, create identities without an institution, a piece of art without galleries, a book, an article or music without agencies or editors, a social network without Facebook, a Uber service without Uber, and the list can go on pretty much indefinitely.\n\nThe video game industry and online ticketing systems are other domains where Ethereum would just do great. \nAn online email platform on Ethereum would definitely put an end to spam and illegal/intrusive advertising, if sending an email costed gas. \nOnline voting and decentralised governance can finally be secure, trustworthy and impossible to tamper with on Ethereum.\n\nFinance would be completely disrupted and rewired from scratch, diluting and redistributing power and wealth. All financial products and services that go beyond the simple transaction can be greatly served on the Ethereum platform without banks. This includes hedging contracts, sub-currencies, financial derivatives, savings wallets, wills, and definitely some classes of full-scale employment contracts. Semi-financial applications, where monetary and non-monetary components co-exist in the same transaction are also straightforward. As an example, exchanging money for non-monetary services, like storage, computation, or renting in general.\n\nWith this said, people around the world are misunderstanding Ethereum, confusing it for a currency a la Bitcoin, volatile enough to give joyful moments whenever one cashes out in USD/EUR.\nEthereum is nothing like that. \nWith Ethereum, it is not a matter of how many USD will it be exchanged at a certain day of the year. \nEthereum represents the value of the infrastructure that it leverages to perform operations in the Internet of the future. \nThis is what makes Ethereum priceless.\n\nSkyrocketing ETH/USD\nDespite the speculative opportunity of Ethereum for many, it is undeniable that some organisations finally realised the potential benefits and disruption of such technology. The member list of the Enterprise Ethereum Alliance represents one of the many signs that a technology like this one cannot be ignored and will change the way we do anything that requires the smallest amount of technology. Large corporations have joined already. Among the most prominent ones, BBVA, J.P. Morgan, ING, Microsoft, Intel Santander, Monax, Credit Suisse, UBS, Accenture, Toyota, Thomson Reuters, and the list goes on as published here.\n\n\nSome of the members who joined the Enterprise Ethereum Alliance\nThese organisations realised that the entire internet ecosystem can be disrupted by Ethereum and its Dapps that will need no intermediary to execute without fraud nor service interruption and interference. For the members of the Ethereum Alliance it is mandatory to join the blockchain not to miss the train of opportunities and stay isolated in the old good Internet 1.0. \nAll the members of the Enterprise Ethereum Alliance know that owning Ethereum means owning a piece of the TCP/IP Internet stack of the future.\n\nDo you see Ethereum merely as a cryptocurrency now?",
