【Abstract】Nowadays, blockchain, revolutionary technology with high security and decentralization is widely applied in many industry segments including healthcare, cryptocurrency and so on. Despite its benefit, it is a challenge for blockchain to effectively operate in large-scale networks without compromising security and decentralization properties due to low throughput. Therefore, in this paper, we consider sharding-based blockchain as a solution to overcome this limitation. The objective is to split the network into different shards to process transactions in parallel and reduce quorum size to reach consensus quickly. However, existing sharding-based blockchain networks implement a consensus algorithm for both main and sub-shards, so it is ineffective with different purposes (e.g., to improve security, reduce resource consumption, etc.). Hence, we propose a system with heterogeneous consensus algorithms in shardingbased blockchain to meet different requirements. Experimental results show that the proposed approach improves up to 54 percent of throughout in comparison with benchmarks.
