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 0x648c38c85531e3e0229c76d4e945457097f7364a29c15d12b72b7dd638207be1. Chain 2 (Bitcoin): anchored in block 954342 (2026-06-19T03:22:39Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Kon Chhaura Tor Delkau Sil Ge (Maithili Song)
Aapn Khidaki Band Kare Naite Hoi Jaito Maar
Saraswati Mai Ke Kripa Se Dimpalawa Pass Bhail Ba
Dugo Magariya Saar Kiya Tuntun Par Sisiyail
Ja Chhahi Ta Jone Ge Sona Khush Rakhto Bhagwan
Bhaiya Ho Rakhi Bandhe Aeyah Gadi Safariya Se
Jila Saharsa Ke Bam Baraka Dabang Chhay Ge
Dhaka Dhak Dhuaa Chilam Se Phenke Lagato
Lawandiya London Se Layege Bihar Me Genhu Katawayege
Yadav Ji Beta Ge Chhori Rang Delako Choli
Sarawati Maiya Ke Kripa Se Pujawa Pass Bhele Re
Kate Se Sikhali Ge Dil Dukhawe Ke Tu Loor
Jaha Khushi Milati Hai Re Sona Tum Wahi Rahna
Reel Ke Chakkar Mein Maugi Khana Banabe Bhul Gele
Mohabbat Me Ye Dhokha Aapse Hi Khaya Hai
