The Trust-State Ledger provides a tamper-evident historical record of trust-state transitions, verification events, credential-state changes, and authorization outcomes. It serves as the authoritative audit trail for determining how and when trust-state conditions were established, validated, or revoked.
Purpose of the Ledger
The Ledger ensures that past trust-state decisions can be independently reconstructed and evaluated. It enables auditors, compliance teams, and relying parties to verify that actions were taken under valid trust-state conditions at the time they occurred.
Ledger Characteristics
- Immutable — Recorded entries cannot be altered without detection.
- Ordered — Trust-state transitions are maintained in chronological sequence.
- Verifiable — Each entry is supported by evidence artifacts and verification outputs.
- Independent — Reconstruction does not rely on the original system of record.
Relationship to Certification and Verification
Certification defines baseline compliance. Verification confirms correctness in real time. The Ledger documents the evidence behind each trust-state decision, forming a complete and independently auditable chain of trust.
