D2 MUSIC GROUP, INC. / OPEN VERIFICATION

Check the proof.

Match a file. Verify its Bitcoin timestamp.

Artist workspace
No original-file upload. Hashing runs on your device. This verifier sends only the SHA-256 fingerprint and .ots receipt to the D2MG verification server.

For a declaration proof, choose the exact evidence.json and evidence.json.ots from your bundle. For a file proof, choose your original file and file.ots.

A pending proof needs time to anchor. Public-provider verification relies on Blockstream and mempool.space. You can also verify downloaded receipts with the independent OpenTimestamps client and your own Bitcoin node. A matching proof does not establish ownership or human authorship.
