Pulsar Network

Pulsar Network is a distributed hash table peer-to-peer messaging protocol for the Astreuos Blockchain written in Rust.

Features

• Send and Receive Messages between Peers.
• A Message contains the body, messagekind, nonce and time.
• Message encryption uses chacha20poly1305 and a blake3 hash, of the shared point on curve25519, as the key.
• Peers can be pinged and respond with their public key & routes supported.
• Currently supported routes are Astreuos Blockchain Main & Test Validation.

API

Connect

``` use pulsar_network::{Network, Route};

let route = Route::TestValidation;

let network = Network::configure(route);

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

```

Message

```

use pulsar_network::{Message, MessageKind};

let mut message = Message::new(MessageKind::Block, block in bytes);

```

Broadcast

```

network.broadcast(message);

```

Send

```

network.send(message, peer)

```

Future

• add sender peer ip information to messages
• multithreaded listening
• ephemeral keys & ports
