6 Layers of Protection
Defense in depth with post-quantum cryptography, hashing, ICP-Brasil timestamp, and immutable storage.
Certification Process
Multiple layers of protection ensuring authenticity and forensic integrity of each piece of evidence.
SHA-256 Hash
Unique and immutable digital fingerprint of the captured content. Any change, however small, generates a completely different hash, guaranteeing total evidence integrity.
ICP-Brasil Timestamp
Timestamp issued by a Certifying Authority accredited by ITI, with legal validity recognized throughout the national territory according to RFC 3161.
Blockchain Registration
Hash permanently registered on Polygon, Arbitrum and Optimism. After network confirmation, it is impossible to alter or remove the record, ensuring absolute immutability.
Preserved Metadata
Original URL, source IP, User-Agent, screen resolution and other technical data are preserved, proving authenticity and maintaining chain of custody.
Technical Report
Detailed document with all technical information about the capture, digitally signed and ready for presentation in legal proceedings.

Hi! I saw your Honda Civic 2020 ad. You're selling for R$85,000, right?
That's right! Very well maintained car, single owner.
Looks great! But I need to know: has it ever been in an accident or had any issues? It's very important to me.
Não, nunca teve nenhum problema. Carro em perfeito estado, só uso para trabalho.
Perfect! I'll make the transfer and pick it up tomorrow. Thanks!
