DXOS is a group of technologies that work together:

  • ECHO - Database and reactive state container for offline-first, real-time, collaborative apps.
  • HALO - Identity for decentralized apps.
  • KUBE - Self-contained infrastructure for hosting and operating decentralized apps.

Compare DXOS applications to client-server web applications:

How identity is establishedservers issue session tokens after validating credentials with methods like OAuthpeers obtain identity locally from the HALO PWA or another chosen application installed on the same client device which contains the user's wallet of identity keys.

ECHO

ECHO (The Eventually Consistent Hierarhical Object store) is a peer-to-peer graph database written in TypeScript. ECHO connects to other peers directly via WebRTCopen in new window, and continuously replicates writes with those peers using technologies based on CRDTsopen in new window. ECHO supports multiple concurrent writers collaborating on large objects, bodies of text, and other "custom data models". Peers going offline and returning to reconcile changes with the online swarm are also supported.

HALO

Establishing user identity in a non authoritative internet is hard. Every peer has to learn how to trust each other. HALO is a set of components and protocols for decentralized identity and access control designed around privacy, security, and collaboration requirements.

KUBE

Running an application requires a lot of supporting technology: process monitoring, observability, deployment management, DNS, SSL, ..., etc. KUBE is a compact, self-contained binary that runs anywhere and provides essential services for applications.
