Blockchain-Enabled Approach for Big Data Processing in Edge Computing

Abstract

The integration of blockchain with edge computing technology has emerged as a popular topic in recent years. Edge computing offers many advantages to IoT data computing by reducing the bandwidth in the cloud, whereas blockchain offers a promising solution to the data integrity issues of dynamic edge nodes. There is considerable technological mismatch, however, when employing a blockchain protocol for edge computing. Standard edge nodes usually deal with big data and require constant data exchange over time, whereas traditional blockchains prevent the storage of big data in a distributed network. This study presents a novel blockchain architecture called Recordchain, which is fully adapted to the edge computing environment. The innovative feature of Recordchain is its ability to locate actual data separately while providing security, scalability, and performance, thus addressing the storage utilization issues related to big data. The efficiency and performance of the proposed architecture is further demonstrated experimentally.
