Public Proof Registry
Content Registry
The public ledger for cryptographic proofs. Search, verify, and explore timestamped content from organizations worldwide.
How the Registry Works
Cryptographically Signed
Every proof is signed with ES256 and uses 3-layer timestamp verification.
Publicly Searchable
Search by content hash, title, organization, or creator. No account required.
Independently Verifiable
Verify proofs without trusting us. Public keys at /.well-known/jwks.json
