CBX is an end-to-end encrypted evidence platform built on blockchain (Arbitrum). It gives your important files immutable timestamp proof.
- End-to-end encryption: files are encrypted locally with your wallet private key, so only you can decrypt and view the original content.
- IPFS distributed storage: encrypted files are stored on the IPFS network for persistence, global access and censorship resistance.
- Blockchain evidence: the file fingerprint (hash) and its IPFS address are recorded permanently on-chain, which gives a timestamp proof that cannot be tampered with.
- Public verification: anyone can verify an evidence record without connecting a wallet. Drop in a file (the hash is calculated locally, nothing is uploaded) or enter a hash directly.
- Fees: there are no service fees, only the blockchain network gas fee. Records on the chain are permanent and cannot be deleted.
