• See draft of specification at draft-thomas-crypto-conditions-02.
• The RFC is also on github under rfcs/crypto-conditions.
• The Crypto-Conditions specification is part of the Interledger Protocol (ILP).

We would like a way to describe a signed message such that multiple actors in a distributed system can all verify the same signed message and agree on whether it matches the description.

This provides a useful primitive for distributed, event-based systems since we can describe events (represented by signed messages) and therefore define generic authenticated event handlers.

To install latest release that is on PyPI:
