Tezos
From Just Solve the File Format Problem
Tezos is another in the set of blockchain-related technologies which have become trendy in the 2010s, for uses related to currency, smart contracts, and many other applications. The unique gimmick of this particular one is the ability for the protocols to be amended in a process akin to the game of Nomic, which was created by Peter Suber and written up in a Scientific American column by Douglas Hofstadter in the early 1980s; this is a game in which changing the rules (including the rules that determine how the rules are to be changed) is a move in the game.
