Fejoa: The Portable Privacy-
Preserving Cloud

Fejoa is an open source data sharing platform for sharing data with contacts at the same or a different service provider. Fejoa allows users to migrate their data/account to a different service provider without losing their contacts.

To preserve the privacy of users, the data in Fejoa is concealed from the service provider by employing encryption techniques.

Fejoa is coming soon!

Follow the development on GitLab.

However, as you can guess, there are some downsides with this approach. First, you need a distributed network. This in itself is not much of a problem but requires that somebody is maintaining the distributed network, i.e. runs the bootstrap...
