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 0xb3a0e1fef90b55c704cb3cd9bebd8be82776f78172b68ef12fb8d86323202b97. Chain 2 (Bitcoin): anchored in block 953699 (2026-06-14T22:00:24Z).

Bhauji Mathe Par Utha Da Hamra Daura (Chhath Geeth)
GORE GORE GALIYA PAR KALA TIL ROMANTIC SONG
Dhori Me Chay Piyayala Jija Paiso N Dihala
Tabij Bana Di Ojha Ji Malva Ke Sadi Kat Jaaye
Dhori Me Dhori Nehawa Ke Dhori (Bhojpuri)
Motihari Me Debu Ki Chakiya Me Chali (Bhojpuri)
Motihari Ke Laieka Ha Dhodhi Taika Chuyde (Bhojpuri Song)
Motihari Me Rangaibu Ki Chakiya Me (Bhojpuri)
Motihari Chakiya Tora Penhai Nathuniya Ge (Bhojpuri)
Motihari Mein Debu Ki Chakiya Mein Chali 2 (Bhojpuri)
Holi Me Bhatar Holi Tenge Tenge (Bhojpuri)
Jabse Bhail Viral Bhauji Ke Laika (Bhojpuri)
Hai Rangadar Motihari Jila Ke (Bhojpuri)
Tu Delhi Ki Rani Ham Bihar Ke Raja (Bhojpuri)
Chakiya Me Takiya Dharai Dela Chhaura (Bhojpuri)
Tora Pyar Ke Chakkar Me Labour Me Khatile
OTH KAILA MOT RAJA DHIRE DHIRE CHAT KE (Bhojpuri)
Road Kare Jaam Sareaam Motihari Ke Laika
Motihari Chakeya Likhwale Ae Jaan Thoriya Pa
Kare Puja Path Navratar Motihari Ke Laika
Bhauji Tohara Gaw Me Super Super Mal Badi San
Jawan Gor Holi San Dil Ke Kathor Holi San
Photo Par Bhatar Likh Ke Status Laga Di Ka
Dhori Me Ragde Dadhi Ke Laika Sab Motihari Ke
Milan Abhi Aadha Adhura Ba Gusal Na Pura Ba
