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 0x76e4fe3d3f683f19b4d4d8d3ea34f36faead02425b686a3ef8aae2d18d6aa93c. Chain 2 (Bitcoin): anchored in block 954342 (2026-06-19T03:22:39Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

ណាត់សង្សារទៅបោះបាយបិណ្ឌ
មើលបងយូរៗដូចសមនិងអូន
ម្តងមានកូន ម្តងអត់កូន
ស្រលាញ់គ្នារហូតក្លាយជាតាយាយ
អ្នកមកក្រោយឈរក្រៅបេះដូង
ស្លាប់ក៏មិនឲ្យឃើញមុខ
ជួយចិញ្ចឹមខ្ញុំផងខ្ញុំចិញ្ចឹមខ្លួនឯងលែងរស់ហើយ
មនុស្សស្រីបម្រុង
ទឹកភ្នែកហូរ ចូលកែវស្រា
កុំធ្វើយ៉ាងហ្នឹង
យូរឆ្នាំដែលចាំបង
មានអារម្មណ៍ថាខ្ញុំកំពុងខូចចិត្ត
អ្នកណាធ្វើឱអូនយំ
មិនគួរណាអ្នកបំផ្លាញភាពយុវវ័យខ្ញុំ
បេះដូងអូនមានតែបង KH , Vol. 155
តើប្រើពេលប៉ុន្មានទើបអាចភ្លេចបង
ជ្រុលស្មោះព្រមខូចចិត្ត (SD, Vol.95)
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

ពេលបាត់បងអូនស្រក់ទឹកភ្នែក
សុខៗសង្សារ Call មកសុំបែក
គ្មានបំណងកំដរសង្សារគេ
ចាំទូរស័ព្ទមនុស្សធ្លាប់ស្រលាញ់
ចាត់ទុកអូនជាតុក្កតាក៍បាន
ប្រុសស្មោះមុខម៉េច?
ស្រលាញ់គ្នាមិនគិតលុយទេ
ក្រមុំកាយម៉េម៉ាយចិត្ត
ណាចិត្តក្បត់បងចូលនិវត្តន៍
ស្រីស្អាតតែប៉ុណ្ណឹង
ប្រពន្ទខ្ញុំក្រមុំមិនដូរ
មុនញ៉ែខ្ញុំកក់ពេទ្យទុកផង
ប៉ា! កូនស្រលាញ់គេហើយ
មិនខ្វល់ថាបងទុកអូនជាអ្វី?
