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 0xc9e91ccd2d5c696d25f0c7a1af85db2a5a2d8975f04e34cf087ac52a610b5bce. Chain 2 (Bitcoin): anchored in block 953407 (2026-06-12T19:24:56Z). 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 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

يا عيني افداكي اللي عدو (واجد من غربالي طاحو)
دخان همومي (في اللي بان بعد مده درنه دهب لاكن صده)
علي شارعنا جاي عزيز (جاي يتمشي جاي عزيز)
الهيبه تعرف صاحبها (يا مولا انريده توا ساكن في قليبي من جوه)
اهلا يا مرحبتين (تعال يا عم الشيخ بخرني وارقيني)
فتح نقاله (قلبي مادق عليك انكان اتريد الحق)
الدنيا بلا لاعزاز (هكي هكي حالي بلا لعزاز)
بلا بلا نيله وبلا بلا هم (عندي عادي نفارق عادي)
الفجعه تطلع علي البنزينه (هرب هرب مايهمكش)
وسع وسع للهيبه (طلتنا طله والله ترهب لقلوب)
مايهون غلاهم (بيت بلا دار لقط قلبي كيف الردار)
غاب الحن وغاب زهانا (وجعني حالك يا محبوس)
عايش مبسوط ومعايا اربع خطوط (صوت البارود)
مجرونه خشنه (مزمار النقرة الشهيره لالالالا)
يحسبونا نحنا طايحين (2025 عزقنا واجد واهمين)
