Pulsar Network

Pulsar Network is the distributed hash table peer-to-peer communication protocol for the Astreuos Blockchain.

Features

• send and receive messages between peers.
• messages are contained in an envelope with the context, nonce, sender, route and time.
• message encryption uses chacha20poly1305 and a x25519 blake3 flavor as the key.
• peers can join the network by sending join requests and valid peers returning the nearest peers
• peers can be pinged and respond with their public key and route supported.
• currently supported routes are Astreuos blockchain main and test routes used for validation.

API

Client

use pulsar_network::{Client, Route};

let bootstrap = false;

let route = Route::Test

let seeders: Vec<SocketAddr>;

let client = Client::new(bootstrap, route, seeders);

for (message, peer) in client.messages() {
    println!("Got: {}", message.body);
}

Message

use pulsar_network::{Message, Kind};

let mut message = Message::new(Kind::Block, message_bytes);

Broadcast

network.broadcast(message);

Send

network.send(message, peer)

Improvements

• multi-threading
• ephemeral keys
• bluetooth communication
