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

អនុស្សវរីយ៍ខ្នងភ្នំសំពៅ
ខូចចិត្តពីរដងដោយសារមនុស្សដដែល
ខ្ចីស្រួលទារពិបាក
ខានទាក់ទងគ្នាយូរហើយ
ពេកដែលអូនភ្ញាក់ពីគេង
ក្រយៅនៅម្នាក់ឯង
កំលោះភូមិខ្ញុំនាំគ្នាដកមេ
រាំវង់លង់ស្នេហ៍
ខ្មាសមិត្តរួមជំនាន់
ម្ហូបម៉ែនៅតែឆ្ងាញ់
បើបងព្រមធ្វើសង្សារអូន
កើតក្នុងត្រកូលម៉ែកាច
បើស្រឡាញ់ជួយបង់លុយធនាគារ
ម្នាក់នេះសុំទោសផង
មនុស្សស្មោះជួបតែមនុស្សក្បត់
ម្នាក់នោះប្ដូរឈាមហើយ
សុំទោសរាល់កំហុស
មនុស្សពូកែយល់ចិត្ត
ស្អប់មនុស្សសម្តែង
ស្រឡាញ់បងកំលោះពិត
មនុស្សខូចចិត្ត គិតអីក៏ខូចចិត្ត
រៀបនឹងស្មោះគេក្បត់បាត់
ភ្ជុំបិណ្ឌបាត់សង្សារ
ចង់បុកលុយធ្វើទេវតា
កុំបារម្ភខ្ញុំមានអ្នកផ្សេង
