Analyzing Token Sale Models

Note: I mention the names of various projects below only to compare and contrast their token sale mechanisms; this should NOT be taken as an endorsement or criticism of any specific project as a whole. It's entirely possible for any given project to be total trash as a whole and yet still have an awesome token sale model. The last few months have seen an increasing amount of innovation in token sale models. Two years ago, the space was simple: there were capped sales, which sold a fixed number of

Hard Forks, Soft Forks, Defaults and Coercion

One of the important arguments in the blockchain space is that of whether hard forks or soft forks are the preferred protocol upgrade mechanism. The basic difference between the two is that soft forks change the rules of a protocol by strictly reducing the set of transactions that is valid, so nodes following the old rules will still get on the new chain (provided that the majority of miners/validators implements the fork), whereas hard forks allow previously invalid transactions and blocks to become valid, so clients must upgrade their clients

A Note On Charity Through Marginal Price Discrimination

Vitalik Buterin via the Vitalik Buterin Blog Updated 2018-07-28. See end note. The following is an interesting idea that I had two years ago that I personally believe has promise and could be easily implemented in the context of a blockchain ecosystem, though if desired it could certainly also be implemented with more traditional technologies (blockchains would help get the scheme network effects by putting the core logic on a more neutral platform). Suppose that you are a restaurant selling sandwiches, and you ordinarily sell sandwiches for $7.50. Why did

[Mirror] A Proof of Stake Design Philosophy

Vitalik Buterin via the Vitalik Buterin Blog This is a mirror of the post at https://medium.com/@VitalikButerin/a-proof-of-stake-design-philosophy-506585978d51 Systems like Ethereum (and Bitcoin, and NXT, and Bitshares, etc) are a fundamentally new class of cryptoeconomic organisms — decentralized, jurisdictionless entities that exist entirely in cyberspace, maintained by a combination of cryptography, economics and social consensus. They are kind of like BitTorrent, but they are also not like BitTorrent, as BitTorrent has no concept of state — a distinction that turns out to be crucially important. They are sometimes described as decentralized autonomous

Paribus. Trust Less.

One month ago, Jerome Powell, head of the Federal Reserve in the US, announced that the banking system was sound and robust despite the collapse of several large banks. After raising rates a further 0.25%, he said, “We’re committed to learning the lessons from this episode and to work to prevent events like this from happening again.” As we prepare for another potential 0.25% rate hike on May 3rd, another major bank in the US, First Republic Bank, has collapsed. Its collapse is part of a larger trend of consolidation

These features guarantee the security of the online casino

The reliability and security of online casinos play a particularly important role, because both large sums of money and players' sensitive personal data circulate on the sites. You can often use pure common sense when choosing a safe gaming site. For example, vaguely translated texts and a low-quality user interface may point to suspicious activity, and it is not a good idea to enter, for example, payment information into the casino. Positive reviews from other players on the site can also help in making the right choices. However, there are also

Finns are hard-working gambling enthusiasts and these days the vast majority of this gambling has moved online to various online platforms. When playing at online casinos, the most important feature is of course the secure payment traffic it offers, because players enter their payment information into the sites and large sums of money move through the service. Finnish consumers prefer numerous different and modern options when paying, which is also reflected in the payment options of the online casinos that offer their service to them. Familiar and safe payment methods

Passport of the Future

A few years ago if you were to talk about governments being able to control your money and impose travel restrictions on their citizens most people would roll their eyes and ask where your tin foil hat was. These days however the dystopian future dreamt of by science fiction authors is rapidly becoming a reality. When it comes to dystopian visions of society and governmental overreach, most people’s first thoughts turn to China. Although they may be ahead of the curve at the moment, their path to a digital future
