## Definition

Iroh is a Rust-native peer-to-peer networking library built by [n0-computer](https://github.com/n0-computer/iroh) that lets applications connect devices by cryptographic public key instead of IP address. Its tagline — "dial keys, not IPs" — captures the core shift: your app hands Iroh a NodeId and it finds the fastest direct path, regardless of NAT, firewall, or network topology.

On June 15, 2026, n0-computer shipped [Iroh 1.0](https://www.iroh.computer/blog/v1): the first stable release with a locked wire protocol, QUIC multipath and NAT traversal, browser/WASM compilation, and official FFI bindings for Python, Node.js, Swift, and Kotlin alongside Rust. The public relay infrastructure has seen 200 million endpoints created in the 30 days leading up to 1.0, signaling production scale across IoT, AI infrastructure, file sync, and secure messaging.

## Analogy

Think of it as a phone book that replaces every street address with a fingerprint — you dial the fingerprint, Iroh finds the house.

## Why it's emerging now

Iroh 1.0 shipped June 15, 2026 — the first stable release after 65 versions and 4 years of development. Multi-language FFI (Python, Node.js, Swift, Kotlin) and a locked wire protocol now let non-Rust teams embed production-grade P2P connectivity without custom NAT traversal stacks. The HN launch scored 1,315 points in 24 hours.
