p2p

P2P networking for ZkVM

This is a p2p framework for ZkVM. It is written in modern async Rust with Tokio runtime.

Features

Nodes encrypt and authenticate connections with C Y B E R S H A K E protocol, inspired by Signal's X3DH with a pinch of YOLO in it.

Simple node discovery logic with embedded miniature web-of-trust (with a narrow meaning of "trust").

Example

Run in multiple Terminal windows:

$ cargo run --example chatter

Listening on 127.0.0.1:59610 with peer ID: ca571c6b2e0a7846603b17eeeef70c4b9c171e06924bb4c7a507cf1cf6bbbc3c

Connect other nodes to the first one:

>> connect 127.0.0.1:59610

Nodes will automatically traslate their peers to each other and connect.

Broadcast messages from any node to all others:

>> broadcast Hello world!
...
=> Received: `Hello world!` from 0811c445f2add526678f9ca2639821abe52c6874d0f101b3c6c81597544cd54a
