What it can do

  • Proof Record: Records an AI execution as a Decision Proof Unit (DPU). Creates a cryptographically chained proof record with SHA-256 hash chain. Returns the created DPU with decision_id and chain hash.
  • Proof Verify: Verifies a specific proof record's cryptographic integrity. Checks hash consistency and returns verification status.
  • Proof Chain Verify: Verifies the entire SHA-256 hash chain integrity for a domain. Performs O(n) sequential verification of all Decision Proof Units and reports the first broken index if tampering is

Cronozen Proof — Operational Decision Evidence Platform.

Record, verify, and export AI-assisted decisions as cryptographically chained Decision Proof Units (DPUs).

  • proof_record: Create a DPU with SHA-256 hash chain linking
  • proof_verify: Verify individual proof integrity
  • proof_chain_verify: Validate entire hash chain for a domain
  • proof_get: Retrieve a DPU with full details
  • proof_export_jsonld: Export as JSON-LD v2.0 document
  • proof_public_verify: Public verification without auth

Built for compliance, audit trails, and AI governance.

proof_recordRecords an AI execution as a Decision Proof Unit (DPU). Creates a cryptographically chained proof record with SHA-256 hash chain. Returns the created DPU with decision_id and chain hash.
proof_verifyVerifies a specific proof record's cryptographic integrity. Checks hash consistency and returns verification status.
proof_chain_verifyVerifies the entire SHA-256 hash chain integrity for a domain. Performs O(n) sequential verification of all Decision Proof Units and reports the first broken index if tampering is detected.
proof_getRetrieves a Decision Proof Unit by ID with full details including hash chain position, AI involvement, human control, evidence level, and compliance information.
proof_export_jsonldExports a Decision Proof Unit as a JSON-LD v2.0 proof document conforming to Cronozen Evidence Ontology. Includes compliance status, 6W extraction (Who/What/Where/When/How/Why), hash chain info, and policy snapshot.
proof_public_verifyPublicly verifies a DPU's cryptographic integrity without authentication. Checks SHA-256 hash validity, previous/next chain link integrity, and returns verification status. Anyone can verify — no credentials required.
