melnet2: Themelio's peer-to-peer protocol

melnet2 is Themelio's peer-to-peer protocol. It is an overlay network that can be built over any nanorpc transport. The two important items are:

• Backhaul, which is a trait that fully describes an underlying protocol (e.g. JSON-RPC over TCP, JSON-RPC over HTTP)
  • We provide TcpBackhaul, an high-performance, pipelined implementation of JSON-RPC over TCP
• Swarm, which wraps around a Backhaul to implement an auto-peering peer-to-peer network of nodes implementing some nanorpc RPC protocol.
  • Swarm essentialy adds functionality for discovering peers and forming a randomly structured gossip network to any nanorpc-based system.

See examples/mn2-gossip for an example program.
