Design and Optimization for Storage Mechanism of the Public Blockchain Based on Redundant Residual Number System

Blockchain has a broad development potential and application prospects. At present, huge storage volume on each node has become one of the primary bottlenecks that restrict the expansibility of blockchain. Optimization for storage mechanism has become a necessary way to accelerate the improvement of blockchain. There are a variety of solutions to relieve the storage burden by modifying the architecture of blockchain, but most of them weaken the decentralization property of the system, which is the core advantages of the blockchain. In this paper, an optimization scheme based on the redundant residual number system is proposed to dramatically reduce the storage volume of nodes in the blockchain system, and fault tolerance mechanism is designed based on the new storage scheme. The simulation experiments are performed to prove the effectiveness of the proposed mechanism.
