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 0x7a2f1e15831708846b56cf502b5206af6374d529dd726414819a8699aaa6dd00. Chain 2 (Bitcoin): anchored in block 954587 (2026-06-20T19:10:41Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

គូព្រេងអតីតជាតិ
ភ្លេចរកកូនប្រសារអោយម៉ែ
ឆ្នាំនេះពុកម៉ែសុំចិត្ត
ជឿម៉ែអោយយកប្ដីចាស់
នាងជួយចាប់ក្ដាម
ទឹកភ្នែកស្រក់លើបាយឆា
ចិត្តជាម្ដាយកាយជាឪពុក
ស្វាមីជាទីស្រលាញ់
អូនជាប្រពន្ធគេហើយ
ហាស្លាក់ខ្ជាក់ស្លែង
ចាំសង្សាទៅបោះបាយបិណ្ឌ
តាំងពីចេះស្រលាញ់ខ្លួនឯង
ថ្ងៃណាហូបការខ្លួនឯង
