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
Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x24eb2b386f646cca66822933642e49e95e4f681ebaaab90aab6325bac7d4cfb1. Chain 2 (Bitcoin): anchored in block 953407 (2026-06-12T19:24:56Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Si toute la planete... - Li lingadje di Wallonyie
Because I Am a Girl (« Les Enfantastiques » chantent pour que les droits des filles soient respectés dans tous les pays du monde. Cette chanson a été réalisée en partenariat avec l'ONG plan)
Y'a pas d'raison - Que l'on soit fille ou garcon
Il y a le temps - Et puis aussi le temps
Y'en a qui se régalent - Et y'en a d'autres qui regardent
Pesonne n'est moche, tout le monde est beau
C'est parti pour le grand voyage de la vie
Mais ce jour là, Rosa refusa (Rosa Parks)
Un p'tit oiseau sur la branche (Edith Piaf)
