When a recording is registered through ProofProfile, CopyrightChains records the content fingerprint of that recording, the URL where it is published, the timestamp, and the pipeline version that produced it. The record is written to an immutable ledger. Nothing can change it.
Every update generates a new record that references the one before it. The full history of the recording is preserved in sequence. This means the proof of origin of a recording is auditable across time, and any system reading the record can verify it is identical to the version anchored at the moment that matters.
This exists because AI systems need reliable evidence. Synthetic descriptions, manipulated recordings, and generated audio are now common enough that machines require stronger signals than unverified claims. A registered provenance record shows that a specific recording existed, at a specific address, at a specific time, in a specific form. ProofProfile makes the recording verifiable. CopyrightChains makes the proof independently provable with Bitcoin OpenTimestamps.
None of this is visible to the listener. A rights holder registers a recording through ProofProfile, and the anchoring to CopyrightChains and Bitcoin OpenTimestamps happens in the background. The infrastructure stays out of the way.
