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 0xd71819ade655d7a6da06add56819205a4eb5c6c1420fbd3246b794d0a1e7e5b3. Chain 2 (Bitcoin): anchored in block 954513 (2026-06-20T06:31:18Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Meday Hatha Otay Piyaar Dia Mehdia Na La
Banday Bahu Sar Den Jada Sawal Meda Naal Hudey
Wangray Wangray Waal Way Tur Dey Phullay Phullay
Meko Tedia Akhiya Kalia Bariya Pasand Aaya
Hal Wo Shoneria Akiya Wala Lutya Naza Naal Wo
Main Lamay Pai Wedia Lamay Meda Ghar Mahiya
Allah Karay Baon Jaldi Teday Saday Melay
Dilan Vich Rab Wasda Ay Dil Na Toray Kar
Saday Dil Tu Mit Nai Sagda Teda Peyar Sanwla
Chor Aiyan Main Sara Shahr Mahiya Tedi Yari De Pichay
Medi Tasveer Sajan Teday Dil Utton Mit Gai Ay
Kitho Sewaya Hei Meday Dil Janiyan Chola
Niki Nik Wa Ghulli Ay Sajran De Pasay Di
Kar Faisla Saday Nal Hik Da Banr Da Dhola
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
