D-KaP Blockchain Wrap (part of EpochCore's sealed-evidence product line) takes any compliance artifact — a SOC 2 control test, a HIPAA access log, a contract sign-off — wraps it in a portable verifiable credential, then anchors its fingerprint on a public blockchain so anyone can confirm it existed and has not been changed.
Your auditor, customer, or partner asks: "How do I know this record is real and has not been edited since you signed it?" You hand them a PDF, they have to trust your email server, your file share, and your word. There is no way for them to verify on their own — and no way for them to prove it later to a regulator or court without subpoenaing your systems.
A blockchain anchor closes that loop. A public network records a fingerprint of your document at a specific moment. Anyone can look up that fingerprint forever and confirm the artifact matches.
Blockchain Wrap takes any compliance artifact you send in (JSON, PDF, log file, structured record) and does two things: it issues a W3C Verifiable Credential — a portable, self-contained proof document that follows a worldwide standard for digital credentials — and it anchors a one-way fingerprint of that credential on Base, a public Ethereum-compatible blockchain (Base Layer 2). The original artifact stays private with you. Only the fingerprint goes on-chain. Anyone you share the credential with can independently verify it matches the on-chain anchor without contacting you, without trusting your servers, and without revealing the contents of the artifact itself.
POST your compliance artifact (any file or structured record up to 5MB) to our endpoint with your API key. No special formatting required.
Within seconds you get back a verifiable credential file and a Base L2 transaction hash. Save both. The credential is yours forever.
Send the credential file (or just the link to the on-chain anchor) to your auditor, customer, or counterparty. They run the verification script and get an instant pass/fail. No trust in our infrastructure required.
Example: A digital-asset trust company tests its quarterly proof-of-reserves procedure on March 31. The CCO wraps the test result in a Blockchain Wrap credential. Six months later a regulator asks for proof the test happened on that date. Instead of producing internal logs (which the regulator must trust), the CCO hands over the credential and the on-chain transaction hash. The regulator independently verifies the anchor block was mined March 31, the fingerprint matches the artifact, and the issuer signatures verify against a public root. The conversation is over in under five minutes.
One verifiable wrap costs about as much as one billable hour of compliance consulting. The wrap eliminates the back-and-forth of an auditor asking "can you prove this is the same file?" — a question that often consumes an entire day of email, screenshots, and internal log pulls. For Web3-native firms whose customers expect on-chain proofs as table stakes, this turns a routine ask into a one-line answer.
The same credential, but the embedded artifact also carries an invisible stealth watermark keyed to your account. The watermark survived 90 of 136 measured attack vectors in our test matrix at SSIM 0.985 (visually identical to the original) with zero false-positive matches. It stays attached through screenshots and re-uploads, giving you machine-readable proof of custody. Not "uncopyable" — a determined attacker can still scrub it — but tamper-evident in all the ways auditors and counterparties care about. MEASURED
