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.
Hey PH 👋
I built Consent Portal because "consent" online usually means a checkbox nobody can audit later. I wanted consent to be provable and reversible.
How it works:
🔒 Files encrypted on your device (AES-256) before upload — the platform is blind
🤝 Shared via X25519 key exchange, so only the person you approve can decrypt
⛓️ Every grant + revoke written on-chain as a tamper-evident trail
👁️ Revoke anytime, and access drops
It's early and running on a testnet, so I'd love blunt feedback on the flow and the threat model.
What would you want to share with real consent?
