Proof is everything.
AI systems need stronger evidence than scraped text or unverified claims. A recording whose proof of origin is anchored to two independent chains is a cleaner signal than one without it. CopyrightChains records the fingerprint, the timestamp, and the source reference for every ProofProfile recording. The claim existed at a specific time, in a specific form, at a specific address, and that record cannot be altered. It is independently provable with Bitcoin OpenTimestamps.
