            CRYPTOCURRENCY-BASED LAW



                         Michael   Abramowicz*





Bitcoin is a protocol promoted as the first peer-to-peer institution-an alternative
to a central bank. The decisions made through this protocol, however, involve no
judgment.  Could  a peer-to-peer protocol underpin an  institution that makes
normative decisions? Indeed, an extension to the Bitcoin protocol could allow a
cryptocurrency to make law. Tacit coordination games, in which players compete
to identify consensus issue resolutions, would determine currency ownership. For
example, an issue might be whether a cryptocurrency-based trust should disburse
funds  to a putative beneficiary, and the game's outcome  would  resolve the
question and  result in gains or losses for coordination game participants. A
cryptocurrency can also be used to generate rules or other written codes. Peer-to-
peer  law might be  useful when official decision-makers are corrupt or when
agency or transactions costs are high. A modest starting point for cryptocurrency-
based governance  would be as a replacement for Bitcoin's centralized system for
changing  its source code. A  cryptocurrency incorporating tacit coordination
games  could  serve as a foundation for other projects requiring peer-to-peer
governance, ranging from arbitration to business associations, which would enjoy
inherent limited liability and would lack designated management.
