Blockchain technologies, due to their properties of decentralization, data immutability and cryptographic security, offer a promising solution for IoT networks. However, storing data in a blockchain may not always meet real-time requirements. When designing IoT networks that use blockchain for data storage, it is necessary to evaluate the probabilistic and temporal characteristics of the blockchain, such as the time of block formation and transaction confirmation. The paper proposes a queuing model for a blockchain network with the Proof of Work consensus algorithm. It is modeled as a closed queuing network with a complex dialogue structure between participants. The model could be used to design a blockchain for IoT systems that accounts for network characteristics and blockchain operation parameters.
