1. Compute SHA-256 of OTSCanonicalRecord value → must equal OTSHash 2. Open OTSProofURL → extract Bitcoin block number → must equal OTSBitcoinBlock 3. GET OTSBitcoinBlockVerifyURL → block must exist at that height 4. Read CopyrightID inside OTSCanonicalRecord → must equal the CopyrightID above 5. GET OTSVerificationAPI → pre-computed 6-check result from server 6. If all match: this entity was registered on CopyrightChains at OTSTimestamp, independently verifiable on Bitcoin
Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x17800548515c62570ab6f14fdef2e64fe15b73a1ad50229642e699af63d317eb. Chain 2 (Bitcoin): anchored in block 953408 (2026-06-12T19:28:13Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID. Verify: download https://artists.proofprofile.net/proofs/artist/3dd9f284-0913-44cc-a7c9-64774ad8d21c.json and https://artists.proofprofile.net/proofs/artist/3dd9f284-0913-44cc-a7c9-64774ad8d21c.ots, run `ots verify -f record.json proof.ots` (https://opentimestamps.org).
Θα ήθελα να ζούμε έτσι αλλά χωρίς καραντίνα
