// Package p2p handles peer-to-peer networking for Ethereum Serenity clients.
//
// There are three types of p2p communications.
//
// 	- Direct: two peer communication
// 	- Floodsub: peer broadcasting to all peers
// 	- Gossipsub: peer broadcasting to localized peers
//
// This communication is abstracted through the Feed, Broadcast, and Send.
//
// Pub/sub topic has a specific message type that is used for that topic.
//
// Read more about gossipsub at https://github.com/vyzo/gerbil-simsub
