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.

You install an app, which signs and stores your data on your device.
You share your public data with a random set of peers.
Your peers validate the data against the app’s rules before storing it.
Invalid data triggers a network-wide security response.

App Devs

The community is the infrastructure. Scale with the popularity of your app.
Access other Holochain apps as if they were part of your codebase. No HTTP client, just function calls with optional access control.
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

You choose your own terms. Set privileges, governance policies, and consensus rules according to your needs.
Fast, cheap, and truly peer-to-peer compute and data. No processing fees or block confirmation wait times.
Iterate to perfect. Hard forks aren’t governance crises but opportunities to play a new game.

Next Up for Holochain

Wasmer Upgrade

By upgrading Holochain to utilize the most recent version of Wasmer, it unlocks additional possibilities for the development of Holochain applications that can be compiled for mobile devices.

Workflow Resiliency & Integrity Audit

Workflow reliability tests are conducted to ensure determinism and guarantee data integrity. These tests verify that the workflows perform as expected, and in doing so, they uphold the trustworthiness of the data and the overall robustness of applications.

DeepKey Integration to Holochain

DeepKey would run as the first application installed on a Conductor, before other services, so that it can register and manage keys for any of those hApps or services. This key management system will be made available to all hApps as a Conductor Service.

Performance Testing

Evaluate Holochain's performance over time to identify regressions and understand the impact of new features on its performance, while also providing basic operational performance statistics for Holochain with each release.

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
'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.

Connor Turland demonstrates an inventory app built on hREA to David Atkinson and Arthur Brock
'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
'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!

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 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
