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

Aaiya Ahariyan Rat Me Diya Leke Babi Hat Me
Jay ber lor se gailu gamchha bhijake (Bhojpuri)

Holiya Me Falanawa Bo Baiganwa Leke Sutele
Rangawa Bhitari Se Bahari Le Lagaiye Dihala Na
Bewafa San Se Pahad Tudawaw Baba (Remix)
Jhijhiya Leke Bhaga Mahaul Badale Wala Ba
Bhatar Bhej Ke Bahara Banawatadu Reel Ho
Aeelu Ahir Toli Nacha Raifal Ke Nokh Par
