Interledger Packet Exchange Protocol (PXP)

There has been a lot of discussion about moving on from BTP. I thought it would be a good idea to try and define a single packet exchange protocol that is simple and is not specific to one underlying transport.

I’ve done quite a few experiments in this space over the last few years and PXP is a good approximation of what I think is best for our use case. i.e. A simple protocol for exchanging packets between peers.

It strips out a lot of the unused and unnecessary features of BTP and also provides accommodation for the different deployment scenarios we’ve seen over time.
