Validating ZenBox – a self-hosted encrypted data vault

I'm toying with launching a secure data vault application. It's designed to be a dropbox-like app but you choose where your box is hosted and can permit apps to access your data under strict, revokable protocols. Curious what you think.

The app would start with simple features like secure notes, file sharing and secure messaging and gradually add more sophisticated features like GDPR compliant data sharing, facebook-like feeds and data monetization. The vision is to develop each feature as a means to evolve open protocols for the secure sharing of private data with decentralised applications, moving towards the web3 vision of controlling your own global data footprint. Developers would be free to build apps on these protocols promoting competition and giving the user a choice of UX for each feature. Each protocol would use specifically designed smart contracts to govern access to the data and to act as a digital service level agreement. This puts the data sharing intelligence on chain where it is fully customizable, programmable, transparent, interactive and auditable under the conditions of the protocol.

What do you think? Is it a concept that resonates? Any feedback would be appreciated.
