Abstract

Sharding is one of the mainstream technologies to solve the scalability of blockchain. Sharding can effectively improve the throughput of blockchain. However, the security of sub-chains is poor due to the uneven distribution of computing power of sub-chains. In order to reduce the risk of sub-chains' collusion attack caused by network sharding, this paper proposed an anti-collusion attack network sharding algorithm for blockchain(AANS). The algorithm comprehensively considered the behavior characteristics and the computing power of nodes, polled the malicious nodes among sub-chains, and evenly distributed the computing power of blockchain to sub-chains in order to avoid collusion attack caused by the aggregation of malicious nodes. Simulation experiments verify the effectiveness of the proposed AANS algorithm in term of malicious nodes number, sub-chains' collusion computing power, percentage of sub-chains' collusion attack and percentage of dangerous sub-chains. Simulation results show that AANS algorithm can effectively avoid the aggregation of malicious nodes in sub-chains, reduce the risk of collusion attack in sub-chains, and ensure the security of sub-chains in blockchain.
