Day 1: @EmanAbio and @kimblgn set out the problem.

As agents start acting with real consequences, companies need to prove those agents stayed within the authority they were given.

Logs held by whoever ran the agent can be incomplete or changed later.

How VAA works: the detailed record (prompts, outputs, tool calls, policy decisions) stays private in the company's own Google Cloud Storage.

Cryptographic proofs of that record are stored on @WalrusProtocol and coordinated on Sui. The record stays private; the proof can be checked.

Day 2: Mysten Labs Co-Founder & CTO @evanweb3 on why logs alone aren't enough, and where VAA fits.

Proofs on a public network aren't held by the operator, the counterparty, or Google. If a record is edited later, it no longer matches. Disputes can be replayed against the same receipts.
