Blockchains like Hyperledger Fabric are comparably faster than public blockchains like Ethereum. These Permissioned Blockchains do not need to consider for in-built security like Bitcoin. The core part of Hyperledger Fabric, the orderer, replicates blocks across the blockchain network. The orderer follows the raft consensus protocol, which is already used in many distributed applications, from distributed databases to cloud based systems. However, strong leader based consensus algorithms like Raft have a bottleneck and this limits scalability. Here, we propose an improved raft consensus protocol which is made to perform better, even with an increased number of nodes, by making the leader delegate the responsibility of broadcasting to proxies and just focus on sequencing the clients' commands.

“…This approach is similar to OCC(optimistic concurrency control). Canopus' [14] parallel, network-aware and decentralised consensus protocol designed for large-scale deployments. It achieves scalability by leveraging high performance broadcast support in modern switches and parallel communication along overlay trees.…”

Blockchain is a distributed ledger technology where all nodes in a blockchain maintain the same ledger. The key to a blockchain is to ensure the uniqueness of the ledger. Therefore, different consensus protocols have been designed to cater for different applications. Consensus protocols such as pow and pos allow nodes to enter and leave at any time but still ensure convergence, while PBFT and Raft protocols can speed up convergence in licensed blockchains but are relatively less secure. We analyse consensus protocols from a database perspective and can think of consensus protocols as consistency. We analyze the characteristics of consistency and propose CChain blockchain system, which integrates the eventual consistency method (CRDT) into Fabric for the first time. Compared with the native Fabric, the throughput is improved by more than 16X.
