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 0x7ff21524851ad00d4e744ff8768465d7f51d85cea5bc53c1f9d47a8eb0fa5d8a. Chain 2 (Bitcoin): anchored in block 953899 (2026-06-16T06:37:25Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Panch Varsh Ki Ek Kanya Bundeli Devi Bhagat
Pinda Balam Kachhu Naiya Hamare Bundeli Jawabi Geet
Bhitar Band Kare Rahiyo Thanedar Bundeli Superhit Geet
Ja Kulachhan Mar Jave Chatpate Bundelkhandi Jawabi Lokgeet
Ras Nahi Raye Tome Tai Ho Gayi Bekar Bundeli Lokgeet
Kare Phirat Ladakan Ki Photo Bitiya Set Mobile Mein Bundeli Geet
Kahan Se Humne Byav Kara Layo Superhit Bundeli Geet
Sali Ju Moye Sanchi Batao Bundeli Jawabi Geet
Jab Se Aai Ghar Mein Daati Roj Machi Bundeli Geet
Anand Singh Bablu Bhaiya Ke Birthday (Bhirthday Song)
Kushwaha Ji Jaisan Bhatar Chahi (Bhojpuri Song)
Ghar Ki Bhai Na Rotidar Juthan Khaan Lage
Gori Mose Karke Yaari Deke Daga Chali Gai
Pyari Bitiya Ke Karke Peere Haath Tumay Laane
Yeso Bhav To Pyar Me Daag Lago Salbar Me
Doi Jani Kaay Foolat Apne Apne Ghamand Pe
Kaho Saram Nai Aai Nagin Ki Ki Se Marvai
Bunda Karam Kare Naina Ke Mude Nijaay Re
