[$] Offline applications with Earthstar

Earthstar is a privacy-oriented,
offline-first, LGPL-licensed database intended to support distributed
applications. Unlike other distributed storage libraries, it
focuses on providing mutable data with human-meaningful names and modification
times, which gives it an interface similar to many non-distributed
key-value databases.
Now, the developers are looking at switching to a new synchronization
protocol — one that is general enough that it might see wider adoption.
