Brendan O'Brien - n0, Iroh and the Future of Peer to Peer

66 min • 7 juli 2025

This week we're joined by Brendan O'Brien (b5), founder and CEO of n0, the company behind Iroh - a peer-to-peer networking library that prioritizes reliability and "just works." Iroh enables developers to establish direct, authenticated connections between any two devices using only their public keys, achieving near 100% connection success rates. We discuss the pragmatic approach to P2P networking, why they chose to focus solely on the transport layer, and how Iroh is already running in production on hundreds of thousands of devices.
