Holochain
The current, performant & industrial strength version of Holochain
...Instead of using global consensus, Holochain enables each agent (user) to maintain their own local state while validating actions with a shared set of rules. This allows for scalable, secure, and resilient apps where data is owned and controlled by users. Ideal for social apps, cooperatives, and data sovereignty platforms, Holochain focuses on enabling collaboration without central servers or miners. It offers a complete toolkit for developers to create decentralized, peer-to-peer apps with built-in integrity and trust systems.
