Yde () is a village in the municipality of Tynaarlo in the province of Drenthe in the Netherlands. It lies about 11 km south of Groningen. Yde is twinned with De Punt as Yde-De Punt, however both rema
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 0xed5ceb4c91fd75dd9f124bfea3bd0f26d06285ced376147f8c3f142c56c49377. Chain 2 (Bitcoin): anchored in block 953423 (2026-06-12T21:20:00Z).
