VERA™ Verification Standard: all versions
The evidence-based classification framework of SITP™ (SI Trust Protocol™), formerly AITP.
AITP has evolved into SITP™ (SI Trust Protocol™). The mechanism is unchanged: the same signed records, the same keys and the same resolver, now scoped for superintelligence as well as AI. Everything published under AITP remains valid and verifiable as part of SITP™ (SI Trust Protocol™)’s history. Published versions are never edited in place; a new version supersedes the previous one and the previous one stays readable.
1.3SITP™ (SI Trust Protocol™) edition (current)
Effective: September 26, 2026. Read: veraregistry.com/protocol
Supersedes v1.2 in name only; the classification model, confidence levels, evidence framework and cryptographic integrity sections are unchanged, except the correction of 2026-09-26: records are hashed (SHA-256) and signed, and the QUBIT Blockchain® anchor is planned and not yet live. The protocol is named SITP™ (SI Trust Protocol™) and the AITP Cert becomes the SITP™ Cert.
