If you’re not familiar with the principals of p2p generally and the kind of problems you get into I’d start with building a simple DHT based solution using something like the Chord protocol: https://en.m.wikipedia.org/wiki/Chord_(peer-to-peer) https://en.m.wikipedia.org/wiki/Chord_(peer-to-peer) This will teach you all about adhoc networking, routing, the limitations of different architectures and so on. You could also tackle a real use case like distributed key value storage as a learning device. What you’ll need ultimately will strongly depend on what you intend to build with it.
