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 0xea4b65ce8307f3193910b0edcecb3442e423986807df426a8118ddce51f2dd90. Chain 2 (Bitcoin): anchored in block 954066 (2026-06-17T08:11:48Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Apne Sasure Ke Aage Bahuad Kaise Chalegi
Unche Unche Pahado Pe Maiya Ji Ka Basera Hai
Andar Baithe Hai Kanhaiya Bahar Baithi Tulsa Maiya
Tane Fer Milenge Bhagwan Daan Kariye Do Roti Ka
Maiya Rani Ke Bhawan Mein Hum Diwane Ho Gaye
Chhota Sa Hanuman Chalave Gaadi Satsang Ki
Guru Ji Mane Bete Pale Bahut Pilaya Apna Dudh
Braj Mein Barsana Gaon Radhe Mohe Pyari Lage
Mujhe Le Chaliye Hanuman Maiya Ke Jagrate Mein
Jamuna Kinare Mero Gaon Sanware Aa Jaiyo
