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 entity was registered on CopyrightChains at OTSTimestamp, independently verifiable on Bitcoin

El Preso Nro 9- Señor abogado- Amor gitano
El si de un adiós- Preguntan mis amigos- Cantinero por favor
Las siete de la tarde- Dime amor que está pasando- Ámame
Mendigo sin destino- Asilo de menores- Pocos años
El socio- El fanfarrón- La reina de las feas
La carcel de zin zin-Cancion para un niño solo
