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 0x2bc9a110284d52fb7599c795c55063ed0a6ac3bcd0943fb85a0d769d8567ac0e. Chain 2 (Bitcoin): anchored in block 954342 (2026-06-19T03:22:39Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Gurbet Elde Efkarlıyım / Kız Emine Emine
İçme Demedim Mi Ben / Sabahtan Kalktım Semaver Kurdum
O Yana Dönder Beni / Yumurtanın Kulpu Yok
Zorla Güzellik Olmaz / Meyhaneye Gidelim
Güle Güle Düğün Yapamam / Söyleyin Mahmuduma
