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 0x43146f13b53d150bddcd02343a287f05f1d4968867586e298a6ac37db3913ca1. Chain 2 (Bitcoin): anchored in block 954693 (2026-06-21T11:50:32Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Sueño Profundo Con Lluvia Fuerte Torrencial
Lluvia Relajante en un Día de Tranquilidad
Lluvia en el Bosque Concierto Natural para Dormir
Escucha la Lluvia Caer, Relájate Con Sonidos Agradables para Reducir la Ansiedad
Lluvia en el Bosque, Murmullos de la Naturaleza
Sonido Relajante de Lluvia Tranquila, Susurros del Agua en el Silencio
Sonidos de Lluvia Cayendo del Cielo, Balada de las Gotas
