Chainspace (cryptocurrency)

Chainspace is a blockchain software development company making a distributed smart contract platform. The company is headquartered in Gibraltar, Gibraltar and was founded in 2018 by Dave Hrycyszn, George Danezis, Ramsey Khoury, and Alberto Sonnino.

Chainspace uses the Sharded Byzantine Atomic Commit (S-BAC) protocol that allows Chainspace to run multiple blockchains (shards) at the same time and make atomic cross shard commits. Chainspace also uses a byzantine consensus protocol, called Blockmania, that performs consensus and transaction ordering within one shard and is based on a directed acyclic graph (DAG) structure.
