Diaframma is an Italian band, one of the dark wave, gothic Italian acts to come out of Florence during the early 80s along with Litfiba. Diaframma originated from the meeting of punk - though it was s
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 0x11537d929659309b7f9b0ded3e0f115cbe83b5931fa0b4eed4d436be0c8adda4. Chain 2 (Bitcoin): anchored in block 953407 (2026-06-12T19:24:56Z).
