Security & GovernanceCryptographic audit trails for AI agents: the definitive guide
A cryptographic audit trail for AI agents is a record of what an agent did that can be verified by mathematics rather than trusted by policy. This guide covers the four properties that turn a record into evidence, the open protocols underneath, and a walkthrough you can run yourself.
Security & GovernanceHow to prove what your AI agent did
An overnight refund, walked through a real evidence chain: the envelope that captured the action, the ledger entry that recorded it, the receipt that sealed it, and the offline check that proves none of it was touched afterwards.
StandardsNow you can verify our facts, not just read them
facts.json now ships with a signed WARD receipt: a hash, a chain position, and a signature you can check offline, with no account and no call to us. What that actually proves, and what it doesn't.
ResearchBeyond tamper-evident receipts: why AI evidence needs an independent witness
A hash chain proves a set of records is internally consistent; it does not prove that set of records is the one that existed yesterday. That gap between the two claims is where the interesting attack lives, and better hashing does not close it.
StandardsThe fourth draft: WARD is at the IETF
In February we filed three Internet-Drafts and left the fourth at home, because it was not ready and the site said so. This weekend we audited WARD, found a real defect, fixed it properly, and filed the whole family.
LegalThe Legal Industry's AI Problem Is Not Hallucination. It Is Evidence.
79% of legal professionals use AI tools, yet 44% have no governance. The accountability gap is an evidence problem, not a hallucination problem.
