Open standard
AIVS
AIVS is the “show your work” layer: structured evidence, signatures, and verifier-friendly packaging so integrity claims do not collapse into screenshots.
Definition
What it is
An IETF Internet-Draft that standardizes integrity verification artifacts for agentic systems, aligned with serious compliance framing (including EU AI Act and NIST-oriented language in the draft set).
Who it's for
Builders implementing verification, auditors reviewing evidence, and marketplaces wiring release conditions to proofs.
When to use
- You need a portable proof format, not a proprietary log dump
- You are connecting escrow release to verifier attestations
- You want offline validation of session records
Numbers and limits
- Stands for
- Agentic Integrity Verification Standard
- Core idea
- Proof bundles + cryptography + self-verifiable records
- Pairs with
- VCAP release rules and Conduit-style verification flows
- License
- Dual MIT / Apache 2.0 (like sibling specs)
