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 0x7be8eed85ad80adaa702605d0f1cc471c567e74a32829bbfffb4213c8d533fb6. Chain 2 (Bitcoin): anchored in block 954035 (2026-06-17T02:39:28Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

เพลงนี้เพื่อ(เธอ)
กลับมาได้มั้ย(เธอ)
ฤดูกาลที่ไม่มีเธอ
แค่ฉันอยากจะรู้
ไม่อยากให้เธอรอ
อัศวินหมายจันทร์
นี่เราชอบแกมานานแล้วนะแง ;-;
เธอทำให้ฉันเข้าใจในความรัก
หรือเป็นเพราะฝนที่ทำให้คิดถึง
สุดท้ายก็ต้องลืม
หอบเพลงรักไปสู่ขอ
วางความน่ารักลง ถ้าไม่อยากโดนขโมยหัวใจ
ให้เพลงๆนี้แทนใจของฉัน
น่ารักจริงๆตัวแค่นี้
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
