- RobotChain: A Blockchain for RegisteringPublication . Fernandes, Miguel Ivo Ferreira; Alexandre, Luís Filipe Barbosa de AlmeidaRobots are important equipment in the modern day factory environment. To maintain and improve factory productivity, ledgers containing robotic actions may be used to identify possible bottleneck points in a assembly line or to serve as a record of in unintentional behaviours, be it of a malicious nature or not. Blockchains are a type of secure ledger, that prevent unwanted changes. These blockchains, during their lifetimes, record large amounts of data, that in a common usage its kept on its entirety. This dissertation presents RobotChain, a possible solution using blockchain technology that prevents unwanted changes in a robotic action ledger, and provides a way to use the said ledger in order to aid in production efficiency or other management requirements, and presents a time-segmentation solution for devices with limited storage capacity, integrated in RobotChain. It also presents various experiments related to the performance of Tezos blockchain network with the various modifications.
