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 0xefad86d4503ec67676c8612a59d63568990cc48e21e1f03fd2d25d8b226719ad. Chain 2 (Bitcoin): anchored in block 953407 (2026-06-12T19:24:56Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Ram Lakhan Mere Lal Maine to Ji Te Pyare Se
Lyu Kaise Bitha Nav Mai Parbhu Jadu Bhara Pave Mai
Peda Bhakti Ka Lale Isne Sicha Kriye Roz
Mithe Ras Se Bhariyori Radha Rani - Lofi
Dekh Liya Sare Ke Firke Matlab Ka Sakal Jamana
Ram Naam Ki Baith Naav Mai Tu Hole Parle Paar
Teri Bahu Dekh Ke Aai Re Kanha Radha Se Naam
Mere Bhole Ki Jata Me Bah Rahi Ganga Dhara - Lofi
Mere Bhole Ki Jata Me Bah Rahi Ganga Dhara
