Mysten Labs and Google are jointly developing a VAA framework to verify AI-agent permissions and execution histories. The concept stores prompts, outputs, tool calls and policy records in the customer’s Google Cloud Storage while linking cryptographic evidence to Walrus and Sui. It also aims to attach verifiable records to interagent transactions and payments, making it possible to trace who did what under which authority. This remains a joint development plan, not an established enterprise-wide standard. Verifying whether records were altered is distinct from judging whether recorded actions were appropriate or answers correct.
