Alkahest

Alkahest is a library and ecosystem for peer-to-peer exchange.

Statements represent obligations within a peer-to-peer agreement, while validators represent conditions under which statements are considered valid.

These compose with each other to eventually enable trading anything for anything else, with flexible per-deal assurance guarantees.
