SSB (Secure Scuttlebutt)[1] has solved all of these problems except the encryption of data using the same key forever. The apps all currently use one identity per device but it's not actually hard to use the same identity on two devices and multiple apps share the same identity commonly. Old versions could of software could be a concern but really that's what Versioned APIs are for. It's a solved problem. The only notable problem with local first dev that I'm aware of currently is storage requirements being confounded by the limited size of SSDs on most people's computers.
