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
Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xcdaa0c88d369f4a86fc9cc47f6045079e79b367301a78a48afc35378031333c3. Chain 2 (Bitcoin): anchored in block 953654 (2026-06-14T16:26:51Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

1. Confirm isrcCode identifies the recording in the pre-2022 source corpus and cc-db-prod record 2. GET OTSVerificationAPI → server-side canonical-record, hash, and attestation checks must pass 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. Confirm CopyrightID is the CopyrightChains transaction hash 5. If all match: the cc-db-prod record is independently anchored on Bitcoin at OTSTimestamp

Ago Hamar Bhatar Chhe Ki Murga Bechai Chhe
Suna Sakhi Sanghe Apna Khagariya Se Kanwar Utay Ley Na
Dil Lagal Chhai Hamar Bhauji He Bholedani Se
Nahi Pata Rahai Ho Baba Tu Etana Dur Basal Chha
Shadi Me Dj Baje Dhama Dham Chhouri Nache Chama Cham
Key Dalalko Ge Rang Deh Las Las Kare Chhau
Raniya Chhori Jalaba Chadhabe Chho Ge May
Dukhiya Par Daho Dhiyana He Chhathi Maiya
Suno Ye Bhoji Mano Kahanwa Chhathi Mai Ke Kara Pujanwa
2020 Me Ba Virus 21 Me Install Kari He Chhathi Maiya
Jila Samastipur Rosara Darbhanga Ke Chhora Dildar Hai Ge Maiya
Ho Bau Toro Barati Layake Jaibo Forchunar Par
Tohara Bulawe Ke Khatir Ae Jaan Hamake Marai Ke Pari
Yekare Duaa Se Chale Bus Relgadi Re Jaan
Dil Okre Se Laglai Je Kismat Me Nai Rahey
