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 0x145c3886d525e9e331de5c6f3c9d3981aaf890ac7d43e711931cf71f56019f16. Chain 2 (Bitcoin): anchored in block 954342 (2026-06-19T03:22:39Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

សាវាដល់អាយុប៉ុន្មាន? (Remix)
សំឡេងម្តាយខ្ញុំ
ឆ្លងឆ្នាំកាន់ដប
បងនៅតែនឹកសង្សារចាស់
ម៉ែឱ្យយកប្តី (ចូលឆ្នាំខ្មែរ)
ឆ្នាំនេះចែកធៀបហើយ (ចូលឆ្នាំខ្មែរ)
ស្រឡាញ់គេភ្លេចស្រឡាញ់ខ្លួនឯង
ស្រឡាញ់គេភ្លេចស្រឡាញ់ខ្លួនឯង (Remix)
ដាក់បិណ្ឌជាមួយម៉ែ
ព្រះរស់ទាំងទ្វេ
មិនឈឺដូចខ្ញុំកុំវិនិច្ឆ័យ
មនុស្សប្រុសជជុះ
ភ្លេចយកសង្សារឱ្យម៉ែមើល
