John Owen Edwards is a British conductor who has been particularly associated with the lyric theatre, especially West End musicals and light opera. He conducted recordings of many of the works with wh
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 0x4a70360b2f3714a7d7226e3cf75140b9fdb5232f1399d966045a70add9102987. Chain 2 (Bitcoin): anchored in block 953599 (2026-06-14T06:43:55Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.
