1. Compute SHA-256 of OTSCanonicalRecord value → must equal OTSHash 2. Open OTSProofURL → extract Bitcoin block number → must equal OTSBitcoinBlock 3. GET OTSBitcoinBlockVerifyURL → block must exist at that height 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 artist was registered on CopyrightChains at OTSTimestamp, independently verifiable on Bitcoin

Nečakaj ma už nikdy, skor než odídeš, miluška moja, nesmúť za mnou
Podivný spáč, vyznání, tisíc mil, já budu chodit po špičkách, co je to láska, povídej
Džbán, svou lásku jsem rozdal, ona se brání, náhrobní kámen
Smůle sbohem dám, až jednou přijdeš, bárka lóra, padám níž
