p2panda

All the things a panda needs

Installation | Releases | Contribute | Website

This library provides all tools required to write a client, node or even your own protocol implementation for the p2panda network. It is shipped both as a Rust crate p2panda-rs with WebAssembly bindings and a NPM package p2panda-js with TypeScript definitions running in NodeJS or any modern web browser.

The core p2panda specification is fully functional but still under review so please be prepared for breaking API changes until we reach v1.0. Currently no p2panda implementation has recieved a security audit.

Features

Generate Ed25519 key pairs.
Create and encode Bamboo entries.
Publish schemas and validate data.
Create, update and delete data collaboratively.
Encrypt data with OpenMLS.
Materialise documents from data changes.
Prepare data for node servers.

Usage

import { KeyPair } from "p2panda-js";
const keyPair = new KeyPair();
console.log(keyPair.publicKey());

use p2panda_rs::identity::KeyPair;
let key_pair = KeyPair::new();
println!("{}", key_pair.public_key());

See the demo application and its source code. More examples can be found in the p2panda-rs and p2panda-js directories.

Installation

If you are using p2panda in web browsers or NodeJS applications run:

$ npm i p2panda-js

For Rust environments run:

$ cargo add p2panda-rs

Benchmarks

Performance benchmarks can be found in benches. You can run them using cargo-criterion:

$ cargo install cargo-criterion
$ cargo criterion
# An HTML report with plots is generated automatically
$ open target/criterion/reports/index.html

These benchmarks can be used to compare the performance across branches by running them first in a base branch and then in the comparison branch. The HTML-reports will include a comparison of the two results.
