A toy QUIC P2P gossip CLI app, written in Rust.
The peer connects to all the other peers and sends them a random message every N seconds. Received messages are printed to the stdout.
To start a peer, obtain a certificate using a tool such as Certbot, or generate a self-signed certificate:
openssl req -x509 -newkey rsa:4096 -nodes -keyout key.pem -out cert.pem -days 365 -subj '/CN=localhost'This will place the binary in target/release/p2p-gossip:
RUSTFLAGS="-Ctarget-cpu=native" cargo build --releaseUsage: p2p-gossip [OPTIONS] --port <PORT>
Options:
--period <PERIOD> Period in seconds, once in this period a random message is sent to all peers
--ip <IP> IP to run on [default: 127.0.0.1]
--port <PORT> Port to run on
--connect <CONNECT> Address of the first node to connect to
--skip-server-verification Do not verify peers' TLS certificates
--cert <CERT> Path to the certificate PEM file [default: cert.pem]
--key <KEY> Path to the secret key PEM file [default: key.pem]
