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 0x9a9f5914b30f68949a9f929924eddfa3bf79f220dd3d4307e39c2da41218f884. Chain 2 (Bitcoin): anchored in block 954618 (2026-06-20T23:05:13Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Bolanharo Pujle Thara Ghat Me Base Jagdish
Ab Thare Chadhno He Adhar Chadhi Pyara Hansa
Bhajan Karle Sumiran Karle Chamda Ki Putali
Ham Panchhi Pardesi Musafir Aaye He Selani
Satguru Aavo Hamare Desh Niharu Me Bat Khadi
Ghana Din So Liyo Re Ab Tu Jag Musafir Jag
Diwane Jag Ja Re Ye He Thagon Ki Nagariya
Mat Kar Man Guman Kesariya Rang Udi Jayego
Muniya Pinjre Wali Tera Satguru He Vepari
Tere Jeb Me Pesa Ho To Daru Pikar Aata He
Tharo Ram Hirde Mahi Bahar Kyo Bhatke Bolte Ko Yad Karle
Jaha Janam Maran Nahi Kal He Ham Yese Nagar Rehte He
