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 0xc5ed02e8a66dcbfca307daca195f54221380a8deb20473d4c92bd325b603dbd2. Chain 2 (Bitcoin): anchored in block 954066 (2026-06-17T08:11:48Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

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 → returns the Bitcoin block hash at height OTSBitcoinBlock; GET https://blockstream.info/api/block/{that hash} → its timestamp must match OTSTimestamp 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 0xda7a1b8d3f308ac3f468fa8e51c6aa59aa9e9d8e06cd3cfa5732be0685f0ae92. Chain 2 (Bitcoin): anchored in block 958480 (2026-07-18T02:58:58Z), registered by our registry partner. The server verifies the private canonical record against OTSHash without exposing internal provider keys.

نهار طحت في الفراش_Nahar tahet fel ferach
Li bgheha galbi daha rabi _ لي بغها قلبي داها ربي
Ya manekderch Ndirak Amour_يا مانقدرش نديرك أمور
Ya bayda laani chitan_ يا البيضة لعني الشيطان
Hiya talbet tallaek wathanat _ هيا طلبت طلاق وتهنات
Ya bead lferek _ يا بعد الفراق قوات المحبة
مايغيرك حالهم مايعجبك زينهم _Mayghayrak halhom mayajbak zinhom
