Scalable & distributed
framework for economic
network coordination
hREA (Holochain Resource-Event-Agent) is an implementation of the Valueflows specification. It enables a transparent and trusted account of resource and information flows between decentralized and independent agents, across and within ecosystems.
How it works
Superpowered coordination
through integration of
Holochain and REA grammars
Simple, composable, and modular economic building blocks
Mix and match the building blocks of hREA's economic kit into something tailored to your needs, minimizing technical overhead.
Economic coordination on Distributed Ledger Technology
Multiple secure network spaces can exist simultaneously and scale to any size, enabling you to strike the perfect balance between data privacy and data commons. Participant relationships form the connections between networks, just like in the real world.
Bring-your-own-user-interface with hREA's Valueflows API
Get an entire backend system out-of-the-box and leverage powerful general-purpose economic planning & accounting tools. Build the tailor-made user interfaces that your scenario needs with our extensively documented APIs and frontend libraries.
Who is hREA for
hREA enables tracking & tracing
value flows for conventional
and alternative economies alike
Organizations and businesses with cross-stakeholder value chains (think supply chains, joint ventures, multi-company collaboration spaces, cooperative and small business economic networks, and more)
The parties involved in loosely coupled economic coordination (think open source projects, artistic collectives, eco villages, makerspaces, mutual credit & mutual aid networks, open value networks, DAOs, and more)
History and Roadmap
"Seed" Stage
September 2018 - December 2018
- Led by David Hand, hREA project was started, called HoloREA initially.
- A demo app was created in Go during Holochain's Go phase.
"Sprout" Stage
January 2019 - April 2022
- Led by pospi, hREA project moved to Rust and was continued through ad hoc development.
- Around 70% towards the goal of usability of the API for developers accomplished (to be able to implement applications on top of API).
First Major Milestone Release ("Sapling")
May 2022 - September 2022
- Led by Sprillow, hREA reached a fully usable API (v0.1.0-beta).
- Launched accompanying documentation at docs.hrea.io.
"Tree" Stage
October 2022 - August 2025
- Led by Leo Bensman, through Lightningrod Labs, the first applications on top of hREA began to be built.
- Based on user and developer feedback, hREA continued to be enhanced, including...
- Full rewrite for performance, integration with Moss.
Growing in the Forest
September 2025 onward
- Continuing to be led by Leo Bensman, in collaboration with the Holochain Foundation.
- Enhancements based on application project feedback continue.
- The hREA's Community of Practice is being grown.
- Sustainable funding patterns are being built.
