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 0x05cf05c61ac8c6da6dab1140dafc78d3bf10e27e2c091bd31c065b17d92e8bc6. Chain 2 (Bitcoin): anchored in block 953407 (2026-06-12T19:24:56Z). 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

Sola Sal Umariya Dekhi Dil Me Baje Gai Ghanti
Pardeshi Chhaila Mokho Dhokho Na Daiyo Pyar
Javani Daga Na De Jabe Piya Karva Lo Gauno
Aao Raja Tumhen Dikha De Nai Nai Khuli dukan Re
Dhaka Laga Nahin Pane Tum Jaisan Ke Lane
Recharge Bada Dav Bhadoona Ko Vyav Kara Dav
Main To Doodh Nipaniya Lai Rani Kushwaha Jhansi Vali

Mori Takdeer Badal Gai Jabse Mili Gharvali
Hil Mil Ken Rane Jane Kabe Kiye Mar Jane
Mori Kardo Samsya Solve Jeeja Ju Bhardo Hava
Agar Hamao Pappu Gusseya Je Gori Tumai Munni Chichya Je
Jab Se Chale Je Mobile Sabko Hal Baho Behal
Sakri Gel Hai Raja Dheere Dheere Jan Do Tem Chay Lag Jan Do
Ham Tumhe Itna Pyar Karenge Sal Men Moda Char Karenge
Bitiya Ho Rahi Aaj Parai Babul Lelo Kanyadan
Jhanda Moro Lagaye Danda Lagaye Kau Aur Ko
Baj Rai Dhol Nagariyan Nachaniya Dunar Ho Ho Jaye
Man Karma Bai Ki Khichdi Khane Aaye Jagannath
Jivan Ki 4 Baten Chori Chugli Madira Aur Chhod Parai Nar
Jab Me Ho Gai Javan Raja Karan Lage Hairan
Sosan Sukhi Muiyan Ri Moye Mile Sharabi Saiyan
Jis Ko Maine Apna Samjha Vo Nikla Begana
Hamne Dekh Lao Tumay Ghare Ho Rao To Haul
Yarran Yarran Bhaiyan Bhaiyan Karva Det Ladai
khurd Masaura Men Baithi Dekho Maiya Kali
Aagaddam Bagaddam Ladka Jyada Bitiyan Kam
Sab Ke Sahare Lakhon Mujhe Shyam Ka Sahara

Bhaiya A Rahi Karva Chauth Kharcha Hobe Bhaut
Chaliyo Raja More Sange Tumhen Karen Pyar Ham
Ghar Ghar Prem Barse Dadu Sabke Dil Me Bas Rahe

Singha Pe Hoke Savar Chali Aa Man Jagdambe
Hala Hala Ke Hari Saiya Pani Nikro Naiya
