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 Note: an OTS proof may carry multiple Bitcoin attestations; OTSBitcoinBlock is the earliest confirmed one — a later attestation inside the proof corroborates it and is not a mismatch
Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xe6c4dffcf2debb747fecea76d63399a989c186c76270b2caf341d372d416a45c. Chain 2 (Bitcoin): anchored in block 953407 (2026-06-12T19:24:56Z).

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 Note: an OTS proof may carry multiple Bitcoin attestations; OTSBitcoinBlock is the earliest confirmed one — a later attestation inside the proof corroborates it and is not a mismatch

Tataiya Bairi Khaye Te Mero upro Sabro gaat
Kaai Din Latth Bajvavegi Tu Bhari Jawani Me
Mero Tod Gayi Vishwas Bani Tu Gair Ki Ghar Wali
Bahan Mero Balam Nasedi Din Chhipte Hi Deve Asi Mar
Tu Ban rahi Hai Fulball Jaise Mal Akhade Ki
Sab Rat Chale Tu Waiting Pe Kyo Bole Jhuti Vani
Pyar Ko Toku Shok Lago Hai In Batan Me Kuch Na Rakho Hai
Mere Fode Bahna Bhag Bijri Pade Bichola Pe
Milbe Aaja Re Gurjar Ke Tere Laad Ladaugi
Coaching Ko Bahana Karke Janu Milva Ajio
