A mechanism for verifying digital information provenance and attestation using blockchain distributed ledger technology which reveals unauthorized tampering with credentialed information. Content modifications are detectable leveraging only local edge validation supported by the normative Bitcoin Core cryptographic libraries or equivalent blockchain implementations. The invention prevents unauthorized access, unregulated copy distribution, and orphaned ownership lacking issuer provenance and attestation. The preferred embodiment provides tamper detectable digital content containers supporting credentialing, remote administration, localized validation, distributed access control, and processing instruction signaling. Intermediary third-party services are not required to verify provenance and issuer attestation. Blockchain integrated cryptographic information containers and administrative transactions immutably record the binding between participating parties (e.g., issuer, administrator, requestor) and associated digital assets (e.g., insurance card, medical records, driver's license, passport, biometric, business contract, software application files, data).
