The Capris are an American doo wop group who became a one-hit wonder in 1961 with "There's a Moon Out Tonight." They experienced a popularity and performing resurgence in the 1980s, when three members
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 0xebdc3065bbbe6a96d4fb81df97d8951f5233a904a2ef7d3e7d38104555199b36. Chain 2 (Bitcoin): anchored in block 953407 (2026-06-12T19:24:56Z).
