Blockchain at the Shop Floor for Maintenance

Abstract

Blockchain and Industry 4.0 have the potential to revolutionize the way entities work together in the industrial environment. Former paper-based and manual tasks, such as maintenance, will be replaced by smart contracts in combination with automatic data collection. We consider different data sources and possibilities integrating them into a blockchain ecosystem in consideration of integration and security aspects. We identify potential security threats around the blockchain and propose potential countermeasures. Finally, we provide three solutions to protect blockchain users against three threats targeting data corruption, data protection and input falsification.
