VTI Information

VTI defines open technical standards for evidence-based authorization and verifiable trust-state evaluation. It specifies how trust-state conditions, authorization outcomes, and verification artifacts are expressed in canonical form, preserved with integrity, and evaluated independently of issuing systems. The VTI standard is grounded in three invariants: • Authorization = Evidence • Canonical Trust-State Integrity • Enforcement Bound to Verification These invariants enable digital systems to produce durable, independently verifiable authorization outcomes that remain trustworthy across systems, time, and organizational boundaries. VTI standards and publications are stewarded by VTI Foundation, Inc., which maintains governance, evolution, and open accessibility for implementers, auditors, and regulated industries.
