Method for ensuring data integrity in edge computing networks based on blockchain technology

With the rapid development of edge computing and the increasing number of connected devices, the article addresses the pressing issue of data integrity. It examines the current problem and focuses on the utilization of blockchain technology, which offers unique opportunities for addressing this challenge. The article provides a brief overview of existing methods and proposes a method for ensuring integrity based on blockchain technology. It suggests utilizing the Hot Stuff consensus algorithm in the presence of multiple active nodes, ensuring efficient operation and system scalability. Special attention is given to the utilization of a secondary blockchain based on Ethereum to enhance security and establish checkpoints in large blockchain networks. This facilitates the work of edge servers and enables users to verify data integrity on-demand using smart contracts. New approaches to ensuring data integrity and leveraging blockchain technology also can be used in different implementations of Internet of things.
