Holochain

Holochain is a distributed app framework and P2P networking protocol.

With Holochain, multiple separate p2p networks can be created, each with their own set of rules defined in the networks application code. These rules define things like:

- who can join the network

- data schemas

- who has access to various data

Each network validates the integrity of the data, which is stored in a distributed hash table, using a variety of non-consensus based techniques centred around peer witnessing, hash chains, network warrants, and so on.
