Michael Masley (born September 22, 1952 in Trenton, Michigan, United States) is known for his musical work on the Hungarian cymbalom. His unique method of playing the instrument comes from his inventi
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 0x5de383d1c73cecf8c19c87c82117708ae07e0752e7b5ddda99039c7165b2f6b2. Chain 2 (Bitcoin): anchored in block 953854 (2026-06-15T23:16:56Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.
