About VSO & VeritasChain
The VeritasChain Standards Organization (VSO) is an independent international standards body that develops the Verifiable AI Provenance Framework and its profiles. Its founding idea: codifying trust for the algorithmic age — moving from reputation-based trust to cryptographically verifiable records.
Neutrality, structurally
VSO’s neutrality is expressed structurally rather than asserted: specifications are public (CC BY 4.0) and developed in the open; versions are fixed by SHA-256 digest, and approvals attach to digests, not labels; decision records and review dispositions are kept; and known limitations and project status are disclosed in every public document — including the standing disclosure that there are, as of August 2026, zero external implementations, zero paying customers, and zero Evidence Packs accepted in any proceeding.
VSO’s secretariat and operations are provided by VeritasChain Co., Ltd., a Japanese kabushiki kaisha. The standards body and the operating company are kept distinct in all documents, and the relationship is stated rather than obscured.

How documents are governed
- Digest-fixed versioning. Version numbers identify documents; SHA-256 digests fix exact meaning.
- Disposition-recorded review. Pre-release findings fold directly into drafts with recorded dispositions; approved documents are left untouched.
- Mandatory maturity disclosure. Working drafts state that they are drafts; public materials carry the full status disclosure.
- Framing discipline. VAP is described as tamper-evident (never tamper-proof), post-hoc (never preventive), and a meta-framework (never a protocol).
