A Composite Chain Structure Blockchain Storage Method Based on Blockchain Technology

Abstract

Blockchain is an effective means to store data securely. Existing blockchain systems mostly adopt the equal mining mode, and all bookkeepers (entities) record ledger books on a single main chain, resulting in random data storage in the whole blockchain. Moreover, in complex or classification scenarios, data in a single main chain cannot be correlated or regularly stored, resulting in low storage efficiency. To solve these problems, this paper proposes a composite chain structure blockchain storage method based on blockchain technology. This method firstly proposes the blockchain model of composite chain structure, then constructs the private chain and alliance chain respectively, and finally realizes the adaptive data association storage in complex or classified scenarios. The experimental results show that a composite chain structure blockchain storage method based on blockchain technology proposed in this paper has great advantages in storage efficiency, storage overhead, security performance, availability and other aspects.
