Tove Agélii, known as Toxe, is a Swedish musician and DJ. Known for her experimental club music, she began her career in 2015 by posting her music to SoundCloud. She has since released two extended pl
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 0x0208a943dd9d797216c4d6cc24386b0d17e8f8cb59aa05eaf3eeaa5b9acc7348. Chain 2 (Bitcoin): anchored in block 953407 (2026-06-12T19:24:56Z).
