Holographic storage for distributed applications. A holochain is a validating distributed hash table (DHT) where every node enforces validation rules on data against the signed chains where the data originated - ceptr.org
In other words, a holochain functions very much like a blockchain without bottlenecks when it comes to enforcing validation rules, but is designed to be fully distributed through sharding so each node only needs to hold a portion of the data instead of a full copy of a global ledger. This makes it feasible to run blockchain-like applications on devices as lightweight as mobile phones
# General We have a very active community both for developers and for social designers, on our mattermost server. You can join the channel with this link: - Mattermost holochain.net
There is the ‘general channel where you can ask questions and people will direct you to more specific spaces that hold your interest.
You may also like to check out some of the videos on the Metacurrency:
# For developers There is the holochain github repository, which has a relatively well-stocked wiki, and there is the corresponding gitter channel.
