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 0x7048d19b018b1220585da8ffd8a1e6c7f72c1734c1d3730ee0f5cf217da75435. Chain 2 (Bitcoin): anchored in block 954342 (2026-06-19T03:22:39Z).

Beche Ail Ba Pudina Luchcha Kamina (Bhojpuri Song)
Kon Aaisan Kam Milela Aaram Rat Lihala Par
Dono Hathe Pakad Ke Dale Jala (BHOJPURI)
Rang Dehab Choliya Tohar Kevadiya Band Karke
Kawan Chij Ek Bitta Under Ghusela Maal Fekela Safed
Shadi Se Pahile Kavan Chig Na Dele Ladkiya
Jila Banaras Hav Gori Lahanga Utha Ke Daal Dahi
Sadi Pahin Ke Saiya Aaeeb Kharihani Mein
Ahire Ke Ladka Pe Dil Aa Gyal Babu Radhe Radhe Bola
Ahire Ke Ladaka Pe Dil Aa Gayal Babu Radhe Radhe Bola
Man Ke Silvat Par Kuch Di Jawani Rajau Anatakshi
Man Kere Silavat Par Kuch Di Jawani Rajau Anatakshari
Mehariya Bhi Jaruri Hai Malwa bhi Jaruri hai
Mehariya Bhi Jaruri Hai Malawa Bhi Jaruri Hai
Shadi Ha Hamar Pad Gail Aaj Matamangara Ba
Baje Badhaiya Ghare Me Babuwa Cm Baniye 2
Baje Badhaiya Ghare Me Babua CM Baniye 2
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
