Using blockchain technology in the computer simulation of logistics processes

Blockchain became known to the public in connection with the development of cryptocurrencies. However, blockchain and blockchain technology have much greater possibilities for use within various areas. One of these areas is computer simulation in supply chain and logistics. Integrating the simulation model into the blockchain can present the connection between logistics and blockchain applications. The base of the study was a simulation model of a production line modelled on the logistics principle. The primary goal of this study is to use the blockchain to record, store and verify the authenticity of the simulation model of the logistics process associated with supply in the production process. It is a solution with significant application possibilities through active work with the simulation model and its frequent supply chain and logistics modifications. At the same time, this functionality could be directly integrated into simulation tools in the future. The study confirmed that the simulation model and the results of simulation experiments can be securely written and stored in the blockchain, ensuring their validity, verifiability and trustworthiness. The obtained results in the form of verification of the recording of the simulation model in the blockchain, the use of the blockchain for the validation of the simulation model and the possibility of its download create a prerequisite for its application extension to the field of computer simulation for logistics and application fields of logistics.
