Development of a Method for Ensuring Data Integrity in Edge Computing Networks Based on Blockchain Technology

Abstract

In light of the rapid development of edge computing and the increase in the number of connected devices, this paper addresses the pressing issue of ensuring data integrity. The main focus is on the use of blockchain technology, which offers unique opportunities to solve this problem. This paper provides a brief overview of the existing methods and a new method for ensuring integrity based on blockchain technology. It is proposed to use the Hot Stuff consensus algorithm in the case of multiple active nodes, which ensures fast operation and scalability of the system. Particular attention is paid to the use of a secondary blockchain based on Ethereum to provide additional security and create checkpoints in large blockchain networks. This makes it possible to simplify the work of edge servers and ensure data integrity verification upon the user’s request using smart contracts. The proposed new approaches to ensure data integrity and use blockchain technology can be applied not only in the field of edge computing but also in various variations of the Internet of Things.
