Urbit is a peer-to-peer computer network that runs an operating system (OS) with the aim of giving users digital autonomy. Urbit consists of two pieces of technology: a Peer-to-Peer Computer Network (Urbit ID), which is a distributed identity and public key infrastructure (PKI) for general-purpose authentication; and an Operating System (Urbit OS), which is a virtual computing platform built from the ground up. It is completely isolated from the system it runs on, similar to Web Assembly (WASM) or the Java Virtual Machine (JVM).
