The registry today

The ProofProfile registry holds 2,006,172 music artists notarized on the CopyrightChains blockchain, every one with an independently verifiable OpenTimestamps proof confirmed on Bitcoin (2,006,172 confirmed artist proofs). The registry ledger carries approximately 11,914,250 track-level Bitcoin attestations; 2,934,224 recordings currently publish the complete public proof chain (ISRC + CopyrightID + Bitcoin OTS + audio profile). The public verification API has answered 19,185 proof verifications today.

What this registry answers

Provenance systems like C2PA mark what AI systems generate. ProofProfile answers the other half of the question: did this music exist before generative AI? The registry's evidence base is the pre-2022 AcousticBrainz/MusicBrainz corpus — recordings catalogued before modern generative music systems existed — bound by ISRC to blockchain registration records and independently timestamped on Bitcoin. Anyone can verify any record without trusting this site: hash the canonical record, check the Bitcoin block, confirm the CopyrightID on the chain explorer.
