1. Compute SHA-256 of OTSCanonicalRecord value → must equal OTSHash 2. Open OTSProofURL → extract Bitcoin block number → must equal OTSBitcoinBlock 3. GET OTSBitcoinBlockVerifyURL → block must exist at that height 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 0xd1b9ef2492b126c02c4d63bd1936ff3318d1ad6b8a9f357dffa9681dea4f8d47. Chain 2 (Bitcoin): anchored in block 954066 (2026-06-17T08:11:48Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Erzurum Dağları - O Anılar O Anılar O Yıllar
Gülüşümü Bıraktım - Zamanı Yok Demişlerdi - Öyle Bir Andır Ki O
Hoşgeldin Eskiyen Yüzümün Yeni Gülümseyişi - Gidersin Aklın Kalır
Zor Günlerin Sevdası - Sen Karanlıktayken
Aşka Ve Yola Dair / Düşlerimde Hep Sizler
Gidersen Yıkılır Bu Kent / Tayfun Öncesi Sezsizlik
Yollar Sevda Tutmuyor / Sevgim Elinde Melek Ruhlu Arkadaş
Hangi Günün Yüzyılı / Kelebeğin Ömrü Gibi
1. Confirm isrcCode identifies the recording in the pre-2022 source corpus and cc-db-prod record 2. GET OTSVerificationAPI → server-side canonical-record, hash, and attestation checks must pass 3. GET OTSBitcoinBlockVerifyURL → block OTSBitcoinBlock must exist at that height 4. Confirm CopyrightID is the CopyrightChains transaction hash 5. If all match: the cc-db-prod record is independently anchored on Bitcoin at OTSTimestamp
Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x0fa3e65c539f464cf9b5ba9d2956c6ca9e223ae13047d5f0957d073168d2f458. Chain 2 (Bitcoin): anchored in block 956304 (2026-07-02T03:55:08Z), registered by our registry partner. The server verifies the private canonical record against OTSHash without exposing internal provider keys.
