Blockchain Based Protocol for Economical Communication in Industry 4.0

Abstract

The article presents the architecture of communication protocol for modern industrial processes and business based on cyber-physical systems - Industry 4.0. The main attention is paid to one of the key trends of this concept - to economical autonomous agents i.e. to robots or smart things, which are able to make decisions independently about their economic actions. Agents begin to fully participate in business processes, so it is important to automate the processes and ensure formal and secure communication between multiple heterogeneous agents, taking into account the economic component of the industry. The article shows how to organize economic interaction between agents using a peer-to-peer network based on decentralized Blockchain technology and smart contracts. The general concept of protocol work is described and the experience of its implementation on ROS and Ethereum Blockchain is presented in the form of universal software for different agents. As a result, the experience of applying this solution in various projects is described: a business project with unmanned aerial vehicles (UAV) and an educational project of "smart city".
