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 0xa521f02efd575a546c40d9b2a5abd895f9b506d507e9480e9d7624be5e695770. Chain 2 (Bitcoin): anchored in block 954784 (2026-06-22T02:53:59Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Tore Chalate Giridih Ke Chhodane Kaho Hai Aavara Ge
Chhodi Tora Dekh Ke Byuti Sab Chhodane Maro Hai Siti
Kavan Mangdhovani Delakai Laga Najariya (Khortha Song)
Dekhe Me Toy Lage Chhaudi Ak Piece Maal Ge
Delkay Na Muh Dekhaiya Ho Lal (New khortha song)
Tor Kamar Karadhaniya Jhalak Maro (Bhojpuri)
Ge Gorki Tore Liye Dhowe Tokari (Bhojpuri)
Chhodi Ke Ge Goriya Chal Geli Giridih Sahariya
Gore Gore Galiyan Mai Kala Kala Til Gai (Khortha)
Bhole Baba Lauta Da Hamar Pyar (Khortha)
