Abstract

In order to solve the shortcomings of weak scalability and availability, this paper proposed a parallel storage blockchain digital forensics model based on the combination entrusted equity and practical Byzantine fault tolerance. Firstly, it selected the block producers by the method of delegated proof of stake, and then used the practical Byzantine fault tolerance mechanism to synchronize the block producers. In view of the characteristics that the block chain technology itself was not suitable for storing large capacity data, it applied a combination of blockchain and off-chain storage to overcome this problem. The safety and efficiency analysis of the proposed model proves that it can meet the requirements of safety and performance at the same time, and can serve digital forensics feature well.
