Holochains support decentralized data storage for distributed applications. 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
Holochain is a data integrity engine for distributed applications. It uses a validating DHT (Distributed Hash Table) where every user has their own chain. A transaction is signed and countersigned onto each parties chain and then this information is published to the shared Distributed Hash Table. (Never heard of a DHT? One of the more famous Hash Tables used is found in BitTorrent.) THIS IS NOT a blockchain.
