Bluzelle aims to build a decentralized, scalable database service that provides data storage service for decentralized applications.
The Bluzelle system stores multiple pieces of the same data across the network, preventing the information being lost due to the malfunction of a single node.
However, not every node in the Bluzelle network has a the full copy of the entire blockchain data. Only the nodes within the swarm assigned to the data replicate it. As a result, it results in the formation of small "shards" in the network, which offers greater network scalability.
BLZ tokens are used for accessing the variety of services the Bluzelle network provides.
