1. Compute SHA-256 of OTSCanonicalRecord value → must equal OTSHash 2. Open OTSProofURL → extract Bitcoin block number → must equal OTSBitcoinBlock 3. GET OTSBitcoinBlockVerifyURL → returns the Bitcoin block hash at height OTSBitcoinBlock; GET https://blockstream.info/api/block/{that hash} → its timestamp must match OTSTimestamp 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 0x9df783e2ca6404ab134e3dc31ab28be083608a7877871b7f546353c053c330e7. Chain 2 (Bitcoin): anchored in block 953407 (2026-06-12T19:24:56Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Chama De Velho Da Lancha X 4M Bem Longe Da Crise
Bate Na Cara Da Louca Com Cordão De Ouro
Me Chamou No Instagram Meu Telefone Toca X Ontem Eu Passei Na Globo
De Trem Nós Passa Pelo Morro, Que Mina Linda Que No Baile Eu Vi Passar
Hoje O Mundão Girou, E Quem Torceu Contra Hoje Ve Que Minha Estrela Brilhou
Nós Não É Migo 2 X Migo Nós Não É, Sou Vida Forever
Quando Nós Chega Elas Comenta Que Nòs Tá Pesadão
1. Confirm isrcCode identifies the recording in the pre-2022 source corpus and cc-db-prod record 2. GET OTSVerificationAPI → server-side canonical-record, hash, and attestation checks must pass 3. GET OTSBitcoinBlockVerifyURL → returns the Bitcoin block hash at height OTSBitcoinBlock; GET https://blockstream.info/api/block/{that hash} → its timestamp must match OTSTimestamp 4. Confirm CopyrightID is the CopyrightChains transaction hash 5. If all match: the cc-db-prod record is independently anchored on Bitcoin at OTSTimestamp
