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 0xf4e2a8103247de3d3b083cac26aa9a659b434cf7cc0bd48ab7c859d0209ef38a. Chain 2 (Bitcoin): anchored in block 953885 (2026-06-16T04:12:47Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Tu Kanha Nand Ganv Ka Mai Radha Barsane Ki
Sita Ki Lene Khabariya Chale Lanka Nagariya
Parwat Ki Unchai Chadhai Re Bhole Tere Darshan Ko Aayi Re
Mandir Me Soye Hanuman Ji Koi Jake Jaga Do
Meera Ka Te Baje Iktara Murli Bajawe Nand Laal
