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 0x345ce5026287b07f6b782e3edb2357caaa6c715c1e1069938c4bf8ffb0d22253. Chain 2 (Bitcoin): anchored in block 954659 (2026-06-21T06:14:42Z). 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
Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xd222dc6c90a226a49c25f0723243b371dd40087539f4bd32432b18db8291ff50. Chain 2 (Bitcoin): anchored in block 958538 (2026-07-18T10:30:13Z), registered by our registry partner. The server verifies the private canonical record against OTSHash without exposing internal provider keys.

គេត្រូវគ្នាវិញហើយ
អ្នកស្មោះនឹកអ្នកក្បត់​ (Acoustic Version)
ផ្ញើចិត្តនឹកតាមវិទ្យុ
បើស្រលាញ់បានស្រលាញ់យូរហើយ
គេជាមនុស្សបែបណា
លួចស្នេហ៍ដួងចន្ទ
គេមិនស្រលាញ់យើងទេ
ម្នាក់ឯងម្ដងទៀត
ថ្ងៃនេះមួយឆ្នាំមុន
កើតមកដើម្បីតែលួងគេ
ទោះបងទៅកុំភ្លេចស្រលាញ់បង
