EU AI Act · Article 50 · Enforcing August 2, 2026
LedgerProof generates regulator-verifiable receipts for every AI-generated output your organization produces. Anchored to Bitcoin. Verifiable by anyone in under 10 seconds. Without trusting LedgerProof or any vendor.
Article 50(1)
Receipts capture every AI-mediated user interaction with the disclosure language used, signed by the deployer, anchored to Bitcoin. The receipt format rejects email addresses in policy-protected fields at parse time — GDPR-safe by construction.
Article 50(2)
Receipts cover image, audio, and video outputs with content hash, generation context, and the labeling mechanism applied. Compatible with C2PA and OpenTimestamps for defense-in-depth across the synthetic-media ecosystem.
Article 50(4)
Receipts attach to every AI-generated text artifact your organization publishes or transmits — chatbot responses, generated copy, summarization output, automated decisions. SDK wraps any model call; latency overhead is under 50 ms at the 99th percentile.
Article 50 enforcement begins August 2, 2026. The EU Code of Practice has not finalized. Most Tier-1 EU enterprises do not have a defensible audit trail for the AI deployed inside their own perimeter. The honest answer to "what is our exposure?" is, today: "we don't fully know."
LedgerProof is not a vendor solution that hopes you trust us. It is an open protocol (IETF Internet-Draft draft-dawkins-scitt-ai-article50-00) governed by a US 501(c)(3) Foundation in formation. The receipt format is open. The verifier is open-source. Your team can self-host the operator if procurement requires it. If LedgerProof Inc. fails, the protocol survives.
For the Code of Practice gap: the receipt schema uses a profile system. When the Code specifies a new disclosure obligation, we publish a new profile. Existing receipts remain valid under their original profile. New outputs flow into the updated one. You do not re-paper your AI deployment every time the regulator moves.
