A definition, and where it sits among C2PA, MCP, A2A, and agent identity. provenance standards verification https://provetrail.org/posts/what-makes-an-implementation-conformant/ https://provetrail.org/posts/what-makes-an-implementation-conformant/ Sun, 12 Jul 2026 00:00:00 +0000 An implementation is Provetrail-conformant if it accepts every valid record in the published vector suite and rejects every tampered or malformed one. Conformance is defined by the vectors, not by who wrote the code. conformance standards verification https://provetrail.org/posts/signed-vs-proven/ https://provetrail.org/posts/signed-vs-proven/ Sat, 11 Jul 2026 00:00:00 +0000 A signature proves who emitted a record and that it was not altered afterward. It does not, on its own, prove the work behind it was real. Where the line falls, and the frontier we are building toward. verification cryptography honesty https://provetrail.org/posts/how-third-party-verification-works/ https://provetrail.org/posts/how-third-party-verification-works/ Fri, 10 Jul 2026 00:00:00 +0000 You verify a Provetrail record by rehashing its events into a Merkle root, checking the signature on that root against a published key, and confirming each outcome is bound to committed evidence. All of it runs client-side, in any language, against public conformance vectors. verification cryptography conformance
