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 0x196eed51b44f2fef3a492bb1abfd43f812922f3b512375c3dbd81beaa10f5f58. Chain 2 (Bitcoin): anchored in block 953407 (2026-06-12T19:24:56Z). 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

Kariyo Bhajan Dil Khol Ke Kya Karoge Maya Ko Jod Ke
Manne Dhundh Liye Charo Dham Mile Nahi Ram Yahi To Dookh Bhari Hai
Tanne Fer Milenge Bhagvan Daan Kariye Do Roti Ka
Ye Milte Nahi Doobara Re Karo Maat Pita Ki Seva
Janam Liya Is Jag Me Aayi Kuch Paane Ke Liye
Ram Bhajan Kar Prani Yeh Kaya Teri Ho Gayi Purani
Bahar Khade Bhagwan Manne Ae Satsang Me Jana Se
Maya Maya Maya Guru Ji Main To Maya Me Fas Gayi Re
Gyaras Maiya Se Milan Kaise Hoye Khidki To Sato Band Padhi
Jo Ram Nam Gun Gata Hai Jiwan Me Bada Sukh Pata Hai
Satsangi Chetavni Bhajan Non Stop Bhajan
Sherawali Mata Sunle Teri Beti Rahi Pukar
Teri Sainak Di Bhijwa Choganan Aavegi Ke Na
