PEX specification #543
Description
Right now we have working but very rudimentary PEX. To specify how it should work we need to answer following questions:
- How frequently we want to ask peers for more addresses? Is constant delay OK?
- How should we rank peers for trustworthiness (e.g. whether it returns good or bad addresses)? Should we do it at all?
- How should we remove address from list of known addresses? Nodes will go down and we don't have any mechanism
- How should we try to reconnect to node when connection fails? Is it job for PEX? How should we retry when initiating connection?
