Reference implementation of draft-helmprotocol-tttps (IETF Experimental)
Proof-of-Time attestation — Ed25519-signed timestamps with multi-source corroboration and explicit error bounds. IETF draft-helmprotocol-tttps
EU AI Act Art. 50 — AI-Generated Content Transparency
TTTPS provides cryptographic time-provenance for AI-generated content at the moment of creation. A pot_generate call anchors a tamper-evident timestamp to a cryptographic hash of the content record — independently of any embedded metadata.
C2PA complementarity: C2PA metadata is stripped during recapture, transcoding, and format conversion. TTTPS survives as an external anchor independently verifiable without metadata chain continuity — allowing forensic reconstruction of content provenance even when embedded markers are absent.
GDPR-compatible by design: PoT records contain no content and no personal identifiers. Each record binds a cryptographic hash (SHA-256 + HMAC-SHA256) to a multi-source time attestation. No plaintext content transits or is stored on Helm servers.
