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

Chalo Bhagto Re Mata Ka Bulawa Aj Aya Hai
Karuna Sagar Meri Maa Ho Tum Teri Jai Ho
Aye Pujari Tere Dwar Maiya Darash Dikhado
Maa Daya Karo Maharani Sherawali Kahane Wali

Dukhi Kiya Maat Pita Ko to Bahot Pachhtaoge
Lale Lale Chundri Ohair Ke Elkhin Je Sato Bahin
Piya Ji Bala Ji Javenge Mere Sang Me Kar Le Tyari
Kale Na Somawari Chhodi Bhaiy Geli Jawan
