W3C-compliant SSI you can govern.

Kanon is an open-source self-sovereign identity protocol that runs on any EVM chain. It is built around the W3C DID Core specification and the AnonCreds credential model, with on-chain registries for organizations, DIDs, schemas, credential definitions, and revocation state.

Organizations approve their members, mint their issuer DIDs, register schemas and credential definitions, and revoke per-credential on chain — all gated by role-based access control and pausable by design. Holders present credentials with one of two unlinkability profiles: Mode A for cheap one-time-use on-chain checks, Mode B for Groth16-based zero-knowledge non-revocation proofs.
