Decentralized (censorship-resistant) video is about to transform our societyHow a new #blockchain project might free us from censorship“Two roads diverged in a [yellow] wood, and I, I took the one less traveled by…” — Robert FrostImagine two very different technology futures. In one, we continue on the same path of centralized video delivery platforms — a world where video is stored, transcoded, and distributed from mammoth data centers owned by Facebook, Amazon, and Google. Or another, where video is distributed across a network of decentralized nodes — a world where video (information) is not under the mercy of some single authority.The primary purpose behind this article — other than to present these two different futures — is to guide those readers unfamiliar with a new blockchain protocol, called (...)

What The Heck Are We Going To Do With So Many Stablecoins?With seemingly one new project unveiling multi-million-dollar funding every other week, no one will blame you for questioning there being too many stablecoins out there. Much have already been written about the various approaches which projects use to maintain stability — in this regard we would like to give a special shout-out to the research team at #blockchain.com for their tour de force piece titled The State of Stablecoins, as well as to the many stablecoin aficionados out there curating their research into single convenient destinations.The purpose of this post however, isn’t to compare between the various stability mechanisms and champion a particular argument (it also assumes some level of understanding around the concept (...)

Well, because people have fear… we always fear the unknown, right?. And Blockchains and cryptocurrencies are still too complicated to be understood by the masses. Some time it is difficult to completely understand how they work even for those who already have a technical background.So, now think about the old lady who doesn’t even trust banks (she is right, though), or the guy that lives in your neighbourhood, who doesn’t know how to use a smartphone and comes to ring at your door every time the printer is not printing (and it is usually because his cat walked over the cable and accidentally disconnected the printer cable from the pc, but still after 1000 times he keeps thinking that you are the only one able to solve the mystery!).Anyway, what I am trying to say is that the world is (...)

ICO’s Have All But Completely Exited Stage Left. Enter The Security Token?As the great cryptocurrency winter of 2018 extends its grip by yet another month, anecdotal evidence at various #blockchain conferences worldwide has been rife that a security token wave is on the cusp of forming. This new breed of digital assets is one that seeks to comply with existing regulators, rather than to subvert. Security tokens are are programmatically designed to be compliant with relevant regulations. In the words of influential crypto podcaster and fund manager Anthony Pompliano:If cryptocurrencies like Bitcoin are considered “programmable money” then you can consider Security Tokens a version of “programmable ownership.”With recent examples of assets being tokenized ranging from the St. Regis Aspen (...)

The subject of decentralization is at the forefront of some of the most passionate debates in the security token ecosystem. Whereas the security tokens movement was born as a result of the evolution of decentralized ledgers, the first generation of products in the space have shifted entirely towards centralized architectures. Several of the most revere thought leaders space have been vocal about the diminished role that decentralization should play in crypto-securities compared to the focus on areas such as regulation enforcement and just building better products. While nobody can argue with the value of regulation or better solutions, I think find that perspective a bit short sided. When comes to security tokens, decentralization matters. In fact, I would argue that decentralization (...)

Why blockchains and smart contracts will be useful for both digital and physical assets.via @unsplash by Vincent van ZalingeIn this short piece I will propose a simple and intuitive approach to smart contracts that presents two categories of use cases: 1) internal enforcement and 2) external enforcement. For both of them I will present some examples as well as a brief discussion of their limitations. The goal here is to cut away all the buzz and fog around their potential applications and provide a simple and intuitive starting point for future discussions. Having read many articles and posts regarding smart contracts, I feel the lack of the segmentation I will present below leads to a lot of confusion surrounding their applications, often resulting in a) an over estimation, or b) a (...)

Many are adopting this approach when looking after their crypto portfolio’s. This article provides a comparison of how rebalancing performs when compared to holding.Getting StartedTo begin with a rebalancing strategy, an investor must first determine how much of their portfolio they want to allocate to each asset. In the case of cryptocurrencies, each asset would be a coin. These allocations are simply the percent of each coin that should be represented in the total value of the combined portfolio. When it is time to rebalance the portfolio, the coins are traded such that the value held in each asset is once again equal to the (...)

A technologist by background, this person was struggling to reconcile the computer science-centric methods of the blockchain space with the semi-centralized, red-tape-first approaches that he is seeing in the security token market(I have the same problem BTW).

The following study will evaluate the performance difference between rebalancing on a periodic interval and holding. By examining different intervals, we can determine which rebalancing frequencies had the largest performance increase over simply holding. This study was set up using the following constraints.Trades & DataData was collected from Bittrex starting on March 15th 2017 and ending on October 20th 2018. All of the data points were collected as exact bid and ask values for each asset. This provides the precise prices that would have been used if trades were actually executed at each time. Additionally, all trades included the .25% fee which is standard for Bittrex. A trade from LTC to XRP would therefore first trade from LTC to BTC (which would incur a .25% trading fee) and (...)

But not everyone has gotten carried away, Wharton Legal Studies Professor Kevin Werbach is one such person.In a recent podcast, Werbach said, “Even though we think machines can render contracts effectively, there are lots of situations where they cannot.” This is a good rejoinder to those who proclaim that smart contracts have ‘solved’ contract law or that we can build a future without traditional government or legal systems.“Even though we think machines can render contracts effectively, there are lots of situations where (...)

Citizens voted directly on legislation and executive bills, however, the democracy of Athens was far more primitive than our contemporary paradigm of global democracy. Within Athens, approximately 30% of the population could vote, siphoning equality and equity from the political paradigm of democracy as we know and understand it today. Women could not vote, foreigners could not vote, nor could slaves vote; you had to be a male citizen within Athens to obtain the unique privilege to vote on legislation.

What’s going on? First of all, it is important to remember that there’s nothing new about the price of Bitcoin behaving in this way. Bitcoin’s path to mass adoption is through hype cycles that occur, on average, every two years or so. If we zoom in on the price chart we can see a pattern repeating itself over and over again. The price increases tenfold rapidly and then loses about three thirds of that increase the following year.
