“In 2014, I made a post and a presentation with a list of hard problems in math, computer science and economics that I thought were important for the cryptocurrency space (as I then called it) to be able to reach maturity.

In the last five years, much has changed. But exactly how much progress on what we thought then was important has been achieved? Where have we succeeded, where have we failed, and where have we changed our minds about what is important? In this post, I’ll go through the 16 problems from 2014 one by one, and see just where we are today on each one. At the end, I’ll include my new picks for hard problems of 2019.” (Vitalik)

Based in Moscow, in a large office in the middle of a hipster office cluster, Waves is walking a fine line between being friendly with Russia’s state-controlled corporations (many of which are sanctioned by the U.S. and Europe) and building a positive image for the global market.

The company has recently secured partnerships with several entities linked to the Russian government.


“Defendants’ control of USD₮ issuances and Bitfinex permitted Defendants and their co-conspirators to coordinate purchases and sales with rising and falling Bitcoin prices. When Bitcoin prices were falling, Defendants and their co-conspirators printed USD₮s and artificially increased the price of Bitcoin. Once Defendants and their co-conspirators artificially inflated the price of Bitcoin, Defendants and their co-conspirators then converted the Bitcoin back into USD₮s to replenish Tether’s reserves.
