Proving What Didn’t Happen -SSRN Comprehensive Paper

Sept. 23, 2025
  • Evidentiary compliance reframes legal compliance from procedural trust to cryptographic proof, enabling organizations to demonstrate not only what occurred but also what did not—addressing evidentiary gaps that traditional logs, attestations, and blockchains cannot fill.
  • Audit-Verifiable Compliance Receipts (AVCRs) and Relational Merkle Trees (RMTs) provide legally defensible proof of non-reachability, allowing entities to demonstrate that prohibited access paths or unauthorized interactions were structurally impossible.
  • Lifecycle receipts (CSTPs) and destruction proofs (EIVs) offer cryptographic evidence of compliance with data retention and deletion mandates (e.g., GDPR, HIPAA), enabling reconciliation of conflicting regulatory obligations through verifiable state transitions.
