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 0xf9cd9fa16616df0908b4f368d2ce8eb47eb53a8b177d06f6eea7206b243ff397. Chain 2 (Bitcoin): anchored in block 954667 (2026-06-21T07:29:20Z). 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

ราชาเหมียวครองบ้าน
ร้องเหมียวตามเสียงใจ
เจ้าเหมียวถังแก็ส
ปิดฉากรักคืนเดียว
รถด่วนขบวนไร้เธอ
รถไฟแห่งความอกหัก
รักนี้ได้ล่มไปแล้ว
รักได้ลงจากรถไปแล้ว
สุดท้ายก็ต้องจบ
เหมียวปิดฉากรัก
สอนจระเข้ว่ายน้ำ
เขียนเสือให้วัวกลัว
ชักใบให้เรือเสีย
เลิกสุราเพื่อสุขภาพ
เลิกบุหรี่กันเถอะ
อย่าลืมฝากครรภ์
ขยับร่างกาย ห่างโรคภัย
หันมาดูแลสุขภาพ
