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 0xd8ec723f8d8e825824d3b50dc6b141758c0306ace4964cf3fe7ddb3e9d547339. Chain 2 (Bitcoin): anchored in block 954650 (2026-06-21T04:51:12Z). 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

लंबी जंबी ब्यान गजब की आ लूमा घणी रोड़ीओ राम
काई सेवा में केमी रेगी मारी लाल बियानियां
गुजराता जावो तो जीवडा तरस वो भोला मारु जी
Pedal Pedal Jaau O Nath Gav Khajuriya Dham Pe
Bhojaji Ko Melo Lagyo Asind Re Gad Darbar
Mara Phone Me Status Dekhiya Jagdamba Rani Ka
Chora Mane Bhulgiyo Mara Maa Baap Su Lar
Asind Dekhi Mandariya Vo Dekhi Siloti Wali Biyan
Kharol Diwana Melo Shakambhari Ko Dikha Lajyi Re
Ne Jau Mammi Sasar Koni Jodi Ko Bind Wet
Dekh Dekh Chhora Ne Ghani Etarari Byan Ji
Gori Chale to Le Chalu Karniya Wala Dev Ke
