Consent Portal

Zero-knowledge file sharing with on-chain consent

Consent Portal lets you share personal files with cryptographic consent instead of checkboxes. Files are encrypted in your browser — the server only ever stores data it can't read. Sharing happens through key exchange, every approval and revocation is recorded on-chain, and you can revoke access anytime. Zero-knowledge by design.

Could you build this?

Partial The UI, file storage, and sharing flows are vibe-codeable, but correct end-to-end encryption, key exchange, and smart-contract consent logic need cryptography expertise and a security audit, since mistakes are silent and dangerous.

What it would actually take: Build a browser-side encryption layer (e.g. WebCrypto with X25519/AES-GCM), an encrypted blob store, and a key-exchange protocol for sharing. Consent and revocation records would go on-chain via a smart contract on an L2 or similar chain. The hard parts are getting the key management and access-control design right and having a cryptographer or security firm review it before anyone trusts it with personal files.
