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 0x57dc27e9be21e8bb0a64d1652240257baa0d95e071f4962d99971188c043f9c7. Chain 2 (Bitcoin): anchored in block 954131 (2026-06-17T19:19:19Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

踏山河 是七叔呢 (我在 十面埋伏 四面楚歌的时候)
Something just like this tiktok remix (Remix)
CoCo AiozYoung7 (她會和我分手然後Say nono我也不會在意還會點CoCo)
微微 傅如喬 (微微晨光 點亮這喧囂世界)
虞兮叹 虞兮嘆 闻人听書 (垓下一曲离乱 楚歌声四方)
独家记忆 (我喜歡你,是我獨家的記憶)
我很好 (我很好,反正一直都是偶尔被需要)
忘不了的是你 (忘不掉的是你, 我快不能呼吸)
