Networking and Data Storage Mechanism in Blockchain

Abstract

This paper proposes a blockchain networking scheme based on cloud platform deployment and its adapted data. Firstly, a subnet-based non-all-connection networking scheme is formed, which limits the scope of transaction confirmation to a limited number of nodes. Secondly, the data sharing mechanism of cloud computing divides the data into three levels: transaction data-sensitive state data-non-sensitive state data. The node only saves the transaction data related to the state transition to ensure the non-destructive modification, and the state data is supported by the cloud. The calculated features enable different levels of shared storage, maximizing storage space. The experimental results show that the scheme can provide new ideas for the storage and sharing of trusted data in the blockchain.
