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 0x8475894deec5ce335f4dc8b741f0a646a27a2bcd7de9b74fa32e5b195b09ca4c. Chain 2 (Bitcoin): anchored in block 953641 (2026-06-14T13:54:28Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

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

Kalgeedhar De Puttron Dheeyo Amrit Dhaari Ho Ke Jeeyo
Takriban 513 Saal Pehlan Dhan Guru Nanak Da Hariyavli Baar Updesh Phool Boote Todne Nahin Laune Han
Sikh Wadde Ohde Te Pahunch Ke Vi Man Nu Sewadar Kiven Bana Ke Rakhe
Oho Kede Tin Eide Han Jisde Sadka Guru Wal Ho Janda Hai
Pooran Mahapurush Da Sang Mann Karke Kariye
Jadon Daya Vekh Ke Kahba Vee Satth Koh Agge Aa Gaya (Pashchim Vihar)
Guru Sahib Ji Di Rasna Vichon Nikle Bachan Sadke Tann Te Mann De Rog Aj Vi Raaji Ho Rahe Hann
Guru Naal Panj Taraan Da Pyar Kehrha Hai
Guru Nanak De Ghar Di Pehli Class Ate Aakhri Class Kehrhi Hai
