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 0x9695165dafdb06a5a7f5d5422c1226c7b3d5ce9050cdd143d09042f19d99fd4a. Chain 2 (Bitcoin): anchored in block 953903 (2026-06-16T07:05:05Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Bola Ye Jaan Hame Kaise Bisaraiba (Bhojpuri Sad Song)
Bhangiya Pise Me Mor Narmi Kalaiya (Shankar Bhajan)
Attawar Ke Niharala Mor Motaai Piya Gaili Dubraai Piya Na
Kahe Ke Ruthele Nanadiya Na Kalsa Me Pani Bhare
Sato Janam Rahe Sajana Ke Sath He Bhole Mangile Ashishiya
