An end-to-end open source P2P app framework
Unparalleled coordination and collaboration, at scale
Holochain gives digital agency to organizations, markets, and people. By combining cryptography, distributed databases, and consensus-free validation—new social magic is possible.
AboutLightweight, secure, versatile: made for everyday apps
Think BitTorrent + Git + Cryptographic Signatures
How it Works
Secure and resilient, without servers or blockchains.
1
You install an app, which signs and stores your data on your device.
2
You share your public data with a random set of peers.
3
Your peers validate the data against the app’s rules before storing it.
4
Invalid data triggers a network-wide security response.
App Devs
Serverless
The community is the infrastructure. Scale with the popularity of your app.
Connectable
Access other Holochain apps as if they were part of your codebase. No HTTP client, just function calls with optional access control.
Resilient
Compute and data live at the edges, which means there’s no infrastructure for you to maintain and defend. Holochain automatically adapts to disruptions and threats.
Blockchain Devs
Configurable
You choose your own terms. Set privileges, governance policies, and consensus rules according to your needs.
Scalable
Fast, cheap, and truly peer-to-peer compute and data. No processing fees or block confirmation wait times.
Forkable
Iterate to perfect. Hard forks aren’t governance crises but opportunities to play a new game.
Roadmap
Released
Coordinator updates, memproof security improvements, K2 maintenance and upgrades, authenticating bootstrap server, and various bug-fixes to security, performance, and network reliability.
Infrastructure is operational, with dashboard showing data on key operating envelope metrics

Holochain for Networked Applications
Building the everyday applications that power our lives.
Showcasing the Building Blocks of Holochain
Holochain is a chain like no other: simultaneously a validated onchain experience, and a fully distributed peer-to-peer application framework. This makes Holochain unique in the world of software and distributed networks. Here are a few building blocks that demonstrate what is possible.

Collaboration
'We' is a meta-app or interface for creating groupware that is shareable, forkable, and fusible, giving new powers to self-governing groups. As agent-centric software, each user decides what groups and applets they opt into.

Coordination
'hREA' is superpowered economic coordination for businesses, communities, and commons — and the networks between them. It is simple, modular, and composable for developers to build precisely for their groups' needs.

Synchronicity
'Syn' is a pair of JavaScript and Holochain libraries that work together to demonstrate synchronous coordination with Holochain apps. This allows teams to collaborate with real-time editing during live sessions.
