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 0xa11933a84454a54deb073f7876b20e70a014f835e481c55d8176d5d78a90a8cd. Chain 2 (Bitcoin): anchored in block 953975 (2026-06-16T16:53:41Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Lachmi Pujar Dev Udav Gi NandKo Kalesh Katugi
Lahga Wali Ko Dil Chokho Pajama Wali K Dal M Kalo
Mohabbat Kare To Ab Karle Kawari Chu Kam Aaugi
Mero Dil Royo Jab Aaya Sanam Meri Aakh M Aasu
Bilkul Kam Ku Kar Di jaan Mosu Baat Karbo
Jaanu Tu Ashi Lagh Kha Jau Kokonat Ki Nai
Janu Mhari Dheer Dheer Batla Kan Diwar K
Sawan Me Kub Pujgo Bolo Parwati Ko Motyar
Madam Nem Niba Jayo Tan Man Su Hariduwar Ja Riya Chu
Mat Kh Deewana Milba Ki Dubara Barsaat Aav Gi
Lahga Lugdi Me Lagh R Real Me Chij Brand
Jodu Donu Haat Balaji Nadi K Dai Sasro Hjaya
Jalim Chora K Demo Degi Chilli Chap Chori N
M Gun Ko Bhulu Mammy Ka Balam Milyo Moye Beautyful
Mara Jija Ki Namkin Su Jibh Chtokadi Hogi
Thari Mithi Mithi Bat Mhari Kad Sari Rat
Moku Chhodr Byav Kri Wa Bhi Wa Tene Moj Kari
Teri Si Sem Sakal Bhayeli Mera Bhaisahb Ki Sali
Janu Aaja Chill Karaga Mosam Bahot Khatri
Sari Duniya Hue Divani Khatu SHyam Baba Ki
Pili Lugdi Ke Niche Duba Chunni Me Dikaya Gaal
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
