Cryptographic Trust Layer

HMAC-signed action receipts + tamper-evident audit chains.

Every governed action is cryptographically signed and chained, so any party can verify it was produced by Centertron and never altered.

//What it does
  • HMAC-SHA256 signed receipt on every governed action
  • Tamper-evident hash chain (detects insert/delete/reorder)
  • Per-entry + full-chain verification endpoints
  • Backs the zero-trust claim across Data Exchange & SpaceOS
//Outcomes
  • Provable, non-repudiable audit trail
  • Verify integrity end-to-end
  • Trust by mathematics, not assertion
