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
Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x40b630b9410cbb6b0c6c69526c233ffe0b70d5fddbb8a5a4d0d1c1a6a946373d. Chain 2 (Bitcoin): anchored in block 954555 (2026-06-20T12:10:20Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Senin Yerin Bambaşka / Rüzgar mı Attı Seni
Bizi Çekemediler / Hangi Rüzgar Attı Seni
Maske Varmış Yüzünde / Yalnızlığın Acısını
Bir Gölgeyim Sokaklarda / Bu Akşam Kadehinde
Deli Gibi Sevdim / Sen Mevsimler Gibisin
Sensiz Bizim Sokaklar / Karanlık Bu Bahtım
Yabancı El Değmesin / Dün Gece Meyhanede
