Gazela is a wooden tall ship, built in 1901, whose home port is Philadelphia. She was built as a commercial fishing vessel, and used in that capacity for more than sixty years. She now serves as the
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 0x5d0f88e85abd5bf624b50974d9bb704f55c7c219c5699f8f12fc19e12b320a92. Chain 2 (Bitcoin): anchored in block 953697 (2026-06-14T21:49:28Z).
