File System for Aircraft Maintenance Records Based on Blockchain and IPFS

This study aims to enhance the traceability, data integrity, and transparency of an aircraft's maintenance records while ensuring the records' privacy using blockchain technologies. In this study, a blockchain-based and decentralized model has been developed that enables the digital distribution of maintenance record reports for air platforms, which can be shared peer-to-peer while ensuring report integrity and content confidentiality upon request. An Ethereum blockchain network with a PoS consensus algorithm is preferred for the application of this study. The proposed secure maintenance record storage system for creating a blockchain network is implemented using Ganache and Truffle. This decentralized model provides a reliable file-sharing process that enhances information visibility and reliability among maintenance, repair, and overhaul (MRO) service providers and other stakeholders.
