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 0x1c375e1cac7b81fc9118f35752b6922ec91d3755b9fc5544197ad6ffd6db600d. Chain 2 (Bitcoin): anchored in block 954066 (2026-06-17T08:11:48Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Kait Lelako Gal Pa Datwa Gai Maiyo Ahir Ke Betawa
Kona Me Baith Ke Sasura Me Hamare Lai Kanabai
Akhiya Khojay Chhai Rahiya Bol Sasura Se Abhi Kahiya
Tohar Majanua Hiyo Samastipur Jila Ke Don Gai Pagali
Chalo Jarnetar Dekho Apletor Bol Bhuk Bhuk Karay Chho
Bargar Wala Chhaura Sange Garabar Kelhi Gai
Nashib Me Chho Nehara Oraha Kaha Se Khebahi
Ham Daru Pike Nachabo Jahiya Barat Aaito Ge
500 Ke Not Pe Buleto Ge Dj Wala Maja Leto
Jila Samastipur Me Hamar Lahar Chalay Chhai
Baba Kaniya Diha Gor Reel Bnebe Okre Jor
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
