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 0xe7fb1e84bd51bfb477b85ad74a98c4b4da60d0555643e17ff83895366554a475. Chain 2 (Bitcoin): anchored in block 954066 (2026-06-17T08:11:48Z). 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
Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x23ac5d731fa840a6f628b1962239bb49922f017703ccf7e26ad707a0f8b84e7c. Chain 2 (Bitcoin): anchored in block 958955 (2026-07-21T03:03:40Z), registered by our registry partner. The server verifies the private canonical record against OTSHash without exposing internal provider keys.

ចេះយំនៅពេលស្គាល់អូន
ត្រឹមជាក្មេងស្រែ
ជំនាន់ញ៉ែគ្នាតាមទស្សនាវដ្តី
ភ្លេចរកកូនប្រសារឲ្យម៉ែ
ខ្ចី១០ដុល្លារសិនមក
នឹកក្មេងក្បាលខូច
បក្សអូននិងបងរូបទេវតា
បក្សប្រជាជនលេខរៀងទីប៉ុន្មាន?
បក្សយើងបក្សប្រជាជនកម្ពុជា
ភ្ជុំហើយចូលស្តីអូន
បងអង្កាលចូលស្តី
រៀបការដើម្បីអ្វី ?
ខូចចិត្តមិនហ៊ានប្រាប់ប្រពន្ធ
គេចង់រស់នៅដោយគ្មានយើង
ញ៉ែសង្សារចាស់ (ចូលឆ្នាំខ្មែរ)
អាណិតខ្លួនឯង (ចូលឆ្នាំខ្មែរ)
គេចង់រស់នៅដោយគ្មានយើង (Remix)
ក្រោយពេលគ្មានអូន
ក្រមុំបន្ទំសាច់​
អស់ប៉ុន្មានអស់ទៅ
