Holo

Holochain is a decentralized application platform and post-blockchain ledger system founded by Arthur Brock and Eric Harris-Braun. It utilizes peer-to-peer networking to facilitate agent-centric agreement and consensus without a global consensus model. Each device on the network operates its own chain-based ledger, allowing decentralized applications to scale in multiple dimensions. Holochain is implemented in Go, with flexibility for development in various languages, including JavaScript and Lisp. The platform is designed to be energy efficient and does not rely on mining, minimizing bandwidth and resource consumption.

The architecture of Holochain enables users to maintain control over their data, reducing the risks of third-party exposure. It operates under a non-profit governance model to align the interests of users and developers. Holochain's system allows for individual verification of data between users, which can introduce scalability challenges as data volume increases. The platform is open source and aims to provide a viable alternative to traditional blockchains, focusing on decentralization while addressing potential weaknesses in transaction handling.
