An Adaptive Modular-Based Compression Scheme For Address Data In The Blockchain System

Blockchain has broad development potential and application prospects. At present, the huge storage volume on each node becomes one of the main bottlenecks that restrict the expansibility of the blockchain system, so optimization for storage mechanism becomes an important issue. In this paper, a modularbased compression scheme is proposed to dramatically reduce the storage volume of the account addresses on each node in the blockchain system. The scheme could achieve optimal compression ratio for the different number of accounts by adaptively select the bit-width of the module for each account. Theoretical analysis and simulation experiments are performed to show the effectiveness of the proposed mechanism.
