P2P

Explanation of the Reth P2P Stack design process

• Our initial design exploration started in #64, which focused on layering dependent subprotocols as generic async streams, then using those streams to construct higher level network abstractions.
• Following the above design, we then implemented P2PStream and EthStream, corresponding to the p2p and eth subprotocol respectively.
• The wire protocol used to decode messages in EthStream came from ethp2p, making it easy to get the full stack to work.
