Distributed Storage and Traceability System for Aviation Equipment Biographies Based on Consortium Blockchain

Abstract

Aiming at the safety and efficiency problems in the whole life cycle management of aviation equipment, propose an efficient solution based on federated blockchain. Firstly, the data collected by the terminal sensing device is hash transformed through the blockchain system, and the initial data security is achieved by using the irreversibility principle of the hash algorithm while reducing the data volume of a single transaction in the block; secondly, the block is generated by the representative nodes elected through the Delegated-Proof of Stake (DPoS), and the consensus algorithm of the blockchain data verification adopts the delegated Byzantine Fault-Tolerance (DBFT) consensus algorithm to improve the consensus efficiency; finally, the transaction time curves are fitted and plotted according to the number of participating nodes, block size and network bandwidth in the simulation experiments to calculate the transaction efficiency under different situations. The experimental results show that the federated chain system is proved to achieve secure and efficient aviation equipment history storage and traceability.
