<h2 id="about"><a href="#about">About</a></h2>
<p>p2panda aims to provide everything you need to build <strong>modern, privacy-respecting and secure local-first applications.</strong></p>
<p>We have adopted a <strong>modular approach</strong>—allowing projects the freedom to pick what they need and integrate it with minimal friction. We believe this approach contributes the most to a wider, interoperable p2p ecosystem which outlives “framework lock-in”.</p>
<p>Many of our Rust crates operate over raw bytes and are <strong>fully compatible with your own data types and any CRDT</strong>. In case you don't plan on building your own peer-to-peer protocol, we have you covered with <strong>all features required to build a mobile or desktop application</strong>.</p>
<p>We're using <strong>existing libraries</strong> like <a href="https://github.com/n0-computer/iroh" target="_blank">iroh</a> and well-established standards such as BLAKE3, Ed25519, STUN, CBOR, TLS, QUIC, <a href="https://github.com/ucan-wg/spec" target="_blank">UCAN</a>, <a href="https://en.m.wikipedia.org/wiki/Double_Ratchet_Algorithm" target="_blank">Double Ratchet</a> and more - as long as they give us the radical offline-first guarantee we need.</p>
<p>We want collaboration, encryption and access-control to work even when operating over unstable or ephemeral connections. Towards this end, we're <strong>actively working alongside researchers to design and implement resilient solutions</strong>.</p>
<p>p2panda is "broadcast-only" at it’s heart, making any data not only offline-first but also <strong>compatible with post-internet communication infrastructure</strong>, such as shortwave, packet radio, Bluetooth Low Energy, LoRa or simply a USB stick.</p>
<p>p2panda is a very <strong>multifaceted project</strong>: We maintain our crates, apply for grants, design protocols and do research in radically distributed data-types. We organise community events and write peer-to-peer applications with our friends and collaborators.</p>
