1. Compute SHA-256 of OTSCanonicalRecord value → must equal OTSHash 2. Open OTSProofURL → extract Bitcoin block number → must equal OTSBitcoinBlock 3. GET OTSBitcoinBlockVerifyURL → block must exist at that height 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 0x6875087ca16732ecf1fc319717eeafed45b4a08b908ef528485c5cc793f85f8b. Chain 2 (Bitcoin): anchored in block 954066 (2026-06-17T08:11:48Z).

有沒有一首歌會讓你想起我（走心版）
對你的愛越深就越來越心痛（走心版）

世界上可以不勞而獲的只有貧窮和年齡
用微笑的韻律伴隨每一個春夏秋冬
