VeritasChain Protocol (VCP)

Site-Wide Review: Outdated and Incorrect Statements Corrected on veritaschain.org

On October 7, 2026, VSO published the results of a review of the pages of this website in English, Japanese and Chinese, extending the October 6 corrections (see below) to the rest of the site. Version and status information now matches the published texts — VCP v1.1 (published) with v1.2 as a Release Candidate, VAP v1.2.0 Draft 3, CAP v1.0 and CPP v1.4 — and schedules whose dates have passed are marked as planned with no date set. Regulatory references were corrected. In particular, MiFID II RTS 25 (Delegated Regulation (EU) 2017/574) was repealed with effect from 2 March 2026 and replaced by Delegated Regulation (EU) 2025/1155; pages that explain the EU clock-synchronization rules now cite the new regulation. Statements that claimed more than the specifications provide, or that implied recognition by a regulator or a standards body, were reworded: records made under VSO specifications are tamper-evident, and conformance does not constitute compliance with any law or regulation. Blog posts and the two whitepaper PDFs are kept as dated records. Each blog post now opens with an editorial note, and statements in the posts about legal requirements and about what VSO specifications do were corrected; each PDF now begins with a one-page correction notice, with its original pages unchanged. Duplicate and leftover pages were removed and broken links repaired. The linked comparison lists the changes. Some items that need a decision by VSO remain under review.

Corrections to VAP v1.2.0 Draft 3 and to This Site: Regulatory References and Capability Language

On October 6, 2026, VSO corrected the published VAP v1.2.0 Draft 3 and current pages of this website after checking them against primary legal sources and the specification's normative text. Appendix D of the specification records six editorial corrections with reasons. Three correct regulatory references: a reference to the revoked US Executive Order 14110 was removed; the EU AI Act provisions cited for medical-device, vehicle, aviation and energy AI were corrected or made specific; and the high-risk application dates under the EU AI Act as amended by Regulation (EU) 2026/1744 were added (2 December 2027 for Annex III systems; 2 August 2028 for Annex I systems). Three revise passages on human oversight, interoperability and omission-evidence that claimed more than the normative text provides. No RFC 2119 requirement, field or conformance level changed. The designation remains v1.2.0 Draft 3; spec/v1.2/README.md lists the SHA-256 digest of each published text. On this site, regulatory references and capability language were corrected in English, Japanese and Chinese; the linked change record lists each change. Dated blog posts, the VCP Explorer application, linked PDF and Word files and versioned program documents were not part of this revision. Review of other statements on this site continues.

VSO Publishes VAP Framework Specification v1.2.0 (Draft 3) on GitHub

On September 28, 2026, VSO published the Verifiable AI Provenance Framework (VAP) Specification v1.2.0, Draft 3, on GitHub. VAP is a metaframework: it defines the common requirements that domain profiles inherit, so that records of AI decisions are auditable, attributable and, at anchor granularity, completeness-verifiable after the fact. It does not prevent, block or intercept any AI behavior. v1.2 makes external anchoring mandatory at every conformance level and adds the Completeness Invariant (INT-008): omission of events after anchoring must be detectable by a third party at batch granularity. Under §1.6, conformance does not constitute compliance with any law or regulation and "does not warrant the correctness, fairness, or safety of the underlying AI decisions — only the integrity, completeness (at anchor granularity), and attributability of their records." The draft is pre-release; it has not been adopted by, and has no standing within, the IETF, ISO/IEC JTC 1/SC 42, ITU-T or any other established standards body. Current status: zero external implementations of VAP or of any VAP profile and zero Evidence Packs accepted in any proceeding; the ten paid service contracts that VeritasChain Co., Ltd. holds with European organizations are neither external implementations nor independent validation of VAP. The linked text includes the October 6 corrections (see above).

VeritasChain Co., Ltd. Reaches Ten Paid Client Contracts in Europe

Effective August 28, 2026, VeritasChain Co., Ltd. has reached ten paid service contracts with organizations based in Europe, working in regulatory technology, financial trading, and audit and assurance. The contracts belong to VeritasChain Co., Ltd., the commercial entity, not to VSO, the standards-development organization; client names, contract values, and sector breakdowns are not disclosed. Two milestones remain ahead of the Verifiable AI Provenance Framework itself: a first external implementation, and acceptance of an Evidence Pack in an audit, regulatory, or judicial proceeding. Neither has occurred to date. Securing the first external implementation is the current priority, and the second is downstream of it.

VSO Establishes an AI Research Office in Hokuto, Yamanashi

Effective July 6, 2026, VeritasChain Standards Organization (VSO) has established an AI research office in Hokuto City, Yamanashi Prefecture, Japan — on the southern foothills of the Yatsugatake mountains, about two hours from central Tokyo. The office belongs to VSO, the standards-development organization, not to VeritasChain Co., Ltd., the commercial entity. Its research agenda is deliberately long-horizon: verifiable logging architectures and their real-world failure modes, post-quantum migration for audit-trail infrastructure (ML-DSA / FIPS 204), conformance-testing methodology for cryptographic audit trails, VAP domain profiles beyond finance, and continued alignment with open standards work at the IETF (SCITT / RATS) and the ITU-T. Every output feeds open specifications.

VCP v1.2 Release Candidate Now Available — English, Japanese & Chinese

The VeritasChain Protocol (VCP) v1.2 Release Candidate is now available at github.com/veritaschain/vcp-spec under spec/v1.2/, in English, Japanese, and Chinese. v1.2 is a protocol-compatible, certification-stricter enrichment of v1.1 with zero breaking changes — all v1.0 and v1.1 events and anchors remain valid and verifiable, and the v1.1 hard deadlines (Policy Identification 2026-03-25; Silver external anchoring 2026-06-25) are preserved unchanged. Key additions: strengthened VCP-RECOVERY operational constraints; an ERASURE event type reconciling the GDPR right to erasure (Article 17) with append-only audit trails via crypto-shredding; a version compatibility matrix; SCITT alignment fields; and cross-party (multi-actor) VCP-XREF. The release continues v1.1's alignment with EU AI Act record-keeping (Articles 12, 19, 26, 72) and MiFID II/MiFIR audit-trail requirements. Post-quantum signatures (ML-DSA / FN-DSA) advance to EXPERIMENTAL while Ed25519 remains the default. This is a Release Candidate for public review, not a GA release.

VCP v1.2 Public Review Draft Opening This Week

VeritasChain Standards Organization (VSO) will publish the VeritasChain Protocol v1.2 Public Review Draft (PRD) in the coming days at github.com/veritaschain/vcp-spec. v1.2 is a regulatory-evidence enrichment of v1.1, aligning with EU AI Act Articles 12, 19, 26, and 72; ESMA's February 2026 Algorithmic Trading Supervisory Briefing; and ESMA Q&As 2825 and 2826. All v1.0 and v1.1 anchors remain valid; the v1.1 hard deadlines (PolicyIdentification 2026-03-25; Silver external anchoring 2026-06-25) are preserved unchanged. The PRD ships with JSON Schemas, a Silver/Gold conformance test suite, post-quantum reference vectors, and a CI pipeline. Public Review will run for 45 days. This is a Public Review Draft, not a GA release.

Initial Regulatory Discussion Completed; Next Steps Confirmed

We held an initial discussion with financial supervisory officials overseas to exchange views and clarify scope regarding a previously submitted technical brief. The conversation focused on intent, applicability within the local supervisory structure, and the most appropriate channel for further review. We explained that we are not a trading operator and do not intend to conduct any trading activity. We positioned the initiative as a technical standard and reference implementations for verifiable audit trails, not as a commercial service, client-facing offering, or consultancy engagement. We also clarified that we are not asking regulators to adopt a specific vendor solution or operate any system, and that implementation would typically be carried out by market participants or their chosen vendors. We will provide a concise written document that clearly summarizes our intent, scope, and non-applicable items for internal circulation and routing, after which the supervisory side will determine the appropriate point of contact and follow up after review.
