Abstract
The scale of Internet of Things (IoT) systems has expanded in recent times and, in tandem with this, IoT solutions have developed symbiotic relationships with technologies, such as edge Computing. IoT has leveraged edge computing capabilities to improve the capabilities of IoT solutions, such as facilitating quick data retrieval, low latency response, and advanced computation, among others. However, in contrast with the benefits offered by edge computing capabilities, there are several detractors, such as centralized data storage, data ownership, privacy, data auditability, and security, which concern the IoT community. This study leveraged blockchain’s inherent capabilities, including distributed storage system, non-repudiation, privacy, security, and immutability, to provide a novel, advanced edge computing architecture for IoT systems. Specifically, this blockchain-based edge computing architecture addressed centralized data storage, data auditability, privacy, data ownership, and security. Following implementation, the performance of this solution was evaluated to quantify performance in terms of response time and resource utilization. The results show the viability of the proposed and implemented architecture, characterized by improved privacy, device data ownership, security, and data auditability while implementing decentralized storage.

Accepted: 11 October 2021Over the years, the Internet of Things (IoT) has evolved across different facets of our lives
A permissioned ledger preserves privacy within a network. Members within this network are uniquely identified, resulting in all entities being properly authorized and trusted. These features make this type of blockchain relevant in some use cases, especially those requiring high security and privacy
These include concepts based on deep reinforcement learning [47], artificial intelligence [48,49], and video surveillance systems [50]. Most of these studies used permissionless blockchain, which does not provide adequate privacy. This calls for the design, development, and implementation of an architecture that uniquely leverages enterprise-grade edge computing and permissioned blockchain platforms to achieve security, privacy, data auditability, and distributed storage
Summary
The Internet of Things (IoT) has evolved across different facets of our lives. As the number of IoT devices increases, the amount of data aggregated in a single location, as well as the current storage mode in the present-day implementation of IoT systems, increase. This central data aggregation will result in data management and data ownership issues. IoT 2021, 2 system that can leverage the existing capabilities of edge computing platforms and resolve some of these issues is required to enable the scalable connected future [10] Such IoT solutions generate a vast quantity of data subject to instant processing and analysis to support decision-making. The strength and weaknesses of edge computing concerning IoT must be explored
