Decentralized Maintenance Event Documentation with Hyperledger Fabric
Freie Universität Berlin, Chair of Information Systems, Clemens Wickboldt, Christoph Meise, Natalia Kliewer · 2020
Due to the transparency and redundancy of blockchain, previously required intermediaries become obsolete, which enables the technology to align and digitize business processes in sectors with strong competition and low trust. On the example of the aviation industry, this contribution considers the application of blockchain in supply chains. Complete life cycle documentation is mandatory for safety-related aircraft parts. This work presents and evaluates an IT artefact storing the information of maintenance event certificates in a Hyperledger Fabric blockchain. Our research responds to the calls for practical applications in the blockchain research field. An existing proof of concept is advanced towards a more naturalistic environment by further decentralizing the system. The results suggest a growth in performance in regard to transaction throughput, latency and memory usage by distributing the system on different physical machines. Projectable patterns are identified that can be applied to a broad solution space in similar industry sectors.
