Robots 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.
