Cryptographic identity verification
Prove that person X owns account X. Sigchain, key rotation, document signing. Open source.
Features
Ed25519 signatures, append-only sigchain, client-side verification. The server stores bytes — it can't forge results.
Your browser fetches proofs from platforms and verifies signatures directly. No server trust needed.
Every identity action is a signed, hash-linked chain entry. Key rotation, revocation, and history — all auditable.
Sign files with your identity key. Rekor transparency log timestamps. Multi-party signatures. SSH export for git commits.
Export your identity as signed files. Self-host anywhere. If trust0.app disappears, your identity survives.
Architecture
The server stores bytes. Your browser does the crypto. Nobody can forge a result.
