About

What is CBX?

CBX is a blockchain evidence platform designed to create tamper-proof on-chain evidence for various digital assets, including files, contracts, and agreements. It leverages blockchain technology to provide immutable timestamp proof, ensuring the integrity and authenticity of your important documents. The platform features end-to-end encryption, where files are encrypted locally using your wallet's private key, guaranteeing privacy and that only you can decrypt and view the original content. Encrypted files are stored on the IPFS distributed network for persistence and accessibility, while file fingerprints and IPFS addresses are permanently recorded on the Arbitrum blockchain. CBX also offers a public verification system, allowing users to instantly verify the authenticity and integrity of any evidence record without connecting a wallet.

Best used for

Ideal for lawyers and startup founders who need to secure important contracts, verify legal agreements, and prove file existence at a specific point in time. Especially valuable for ensuring the integrity and authenticity of digital assets with blockchain-backed evidence.

FAQs

Will my file content be leaked when using CBX?

Absolutely not. CBX uses end-to-end encryption, encrypting your files locally with your wallet's private key. Only you can decrypt and view the original content. The blockchain only records a digital fingerprint (hash), not the actual file content.

How do I verify someone else's shared evidence using CBX?

You can use the "Public Verification" feature without connecting a wallet. Simply enter the transaction hash or file link provided by the other party. The system will retrieve public metadata, including the file fingerprint and evidence time, from the blockchain for independent verification.

Does creating evidence with CBX involve fees?

Yes, evidence creation requires a small blockchain transaction fee (Gas fee), which depends on current network congestion. CBX does not charge additional service fees; all fees are transparent blockchain network fees.

Can evidence records created with CBX be deleted?

Evidence records on the blockchain are permanent and cannot be deleted, which is a core advantage of blockchain technology. While encrypted file content is stored on IPFS and can be unmaintained, the blockchain record remains permanently preserved.
