Crate dbc

Deterministic bitcoin commitments library.

Deterministic bitcoin commitments are part of the client-side-validation. They allow to embed commitment to extra-transaction data into a bitcoin transaction in a provable way, such that it can always be proven that a given transaction contains one and only one commitment of a specific type for a given commitment protocol.
