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 Note: an OTS proof may carry multiple Bitcoin attestations; OTSBitcoinBlock is the earliest confirmed one — a later attestation inside the proof corroborates it and is not a mismatch
Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0x6b24f5f431caafe9be9d00d9f5b19d183b81aa39529858273cc4e260d9135061. Chain 2 (Bitcoin): anchored in block 954667 (2026-06-21T07:29:20Z). Bridge: the canonical record inside this Bitcoin proof contains the same CopyrightID.

Aquecimento do pontinho - Beat Série Gold
Só porque sou novinho ta pensando que sou Criança
O carro bicho ta passando, vem mamar eu pilotando
4 MInutinhos de envolvência no beat fino
Hoje é dia de cachorrada, noite das safadas
Calma Não Precisa Brigar Se Organizar Todo Mundo Trepa
SÓ PQ SOU MENORZIN, VOU TE BOTAR COLOCAR
