cyphr

Self-sovereign identity protocol — documentation

cyphr is a self-sovereign identity protocol built on cryptographic state trees. It replaces passwords with public key cryptography, enabling secure multi-device authentication, key rotation and revocation, and individually signed atomic actions — all without a central authority.

Built on Coz cryptographic JSON messaging and MALT append-only Merkle trees.

These docs are under active development. The protocol specification is the canonical reference; the guides here will expand as the project matures.
