Holochain logo

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.

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.

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.

Eric Harris-Braun demonstrates the 'We' application to David Atkinson
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.
Watch on YouTube
Connor Turland demonstrates an inventory app built on hREA to David Atkinson and Arthur Brock
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.
Watch on YouTube
Syn - Real Time Collaboration, a splash screen for a demo video
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.

What the Community is Saying

The Holochain ecosystem is a really fun and exciting place to explore the possibilities and impact of fully distributed, scalable, and peer-to-peer applications!

Holochain is providing the opportunity for people to generate, hold and own their own data so that they can do what they want with it, for the first time ever.

Kathryn Alexander | Australia Founder of Health Commons

Holochain enables collaborative, distributed apps that fit the needs of the communities they serve—without inserting any complicated consensus mechanisms or unnecessary coins to ensure integrity.

Alex Ocean | US

I thought "agent-centric tech" was just marketing. But I realised this shift is actually fundamental in moving towards a world where individual and collective autonomy are honoured.

Holochain is the vision holder for technology that is created to support core human values: agency, connection, and freedom.

Rūta Žemčugovaitė | Germany Humane Tech Advocate
Ruta, supporter from Germany, black and white photo

Holochain just feels right. Everything from the technical architecture, the approach to community, to the broader vision. It feels right and exciting to be playing with all of these wonderful humans.

Guillem Córdoba | Spain Holochain Architect & Community Member
Guillem, supporter from Spain, black and white photo

Holochain has a great collective of people who really want to see a paradigm shift to a more prosocial society and conscious peer-to-peer economic systems.
