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 0x7014d3e78aa67766c0c7a618caf48aab046a74f62813926b8b51b2cfb67fb701. Chain 2 (Bitcoin): anchored in block 954065 (2026-06-17T08:10:43Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Aurangabad Ke Mela Me Mehari Bhula Gaili
SOLAH BARAS TAK SAMBHALNI JAWANI ROMANTIC SONG
Ham Bharat Ke Hindu Hai Yaha Ghar Ghar Bhagwadhari Hai
Maa Ka Pawan Dham Yahan Banate Bigade Kaam
Band Bhail Hujju Wala Kamwa Nandi Ka Pura Bha Sapnawa
Hoy Ga Jiyra Ke Jaraniya Ab Bhajaniya Ke Bina
Balender Peeke Aaunga Silender Ho Jaogee
Chalo Kawariya Shiv Ke Dham Kamariya Dolela (Bhojpuri)
Pakistani Bhauji Pooja Kare Hanuman Ke (Bhojpuri pakistani seema song)
Sri Bageshar Dham Me Jo Bhi Aayega (Hindi)
Mza Jabri Me Na Aawela Mukesh Pandey Ayodhya (Bhojpuri)
Gori Chamdi Sabke Rowaweli (Bhojpuri song)
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 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
