AGNTCon + MCPCon Europe 2026

The EU AI Act makes "what did the agent actually do?" a legal obligation: high-risk AI must support automatic record-keeping over its lifetime (Article 12) — for traceability, human oversight, and post-market monitoring — with logs retained at least six months (Article 19). But the Act can only require the logs to exist, not to be trustworthy: a log is only as good as the party that keeps it, and the operator who ran the action is not a disinterested witness — even an immutable one can be incomplete, cherry-picked, or built after the fact. The fix is simple and old: anchoring. Commit each record to a hash, write that hash to an independent, append-only transparency log, and any party can verify what the agent did — without trusting the operator. This session shows how the Agent Action Capsule project uses open transparency-log standards (SCITT/COSE) to produce anchored, independently-verifiable records of agent actions to the letter of the Act, plus the trust it can't legislate.

Live demo of the Agent Action Capsule project: emit a record at an action boundary, anchor it, verify it with an open verifier, then tamper and watch verification fail. You'll leave with an open, framework-agnostic pattern mapped to Article 12/19 — and a running verifier to try.
