The widespread use of smart devices and city-centric services improves civic life, but also raises concerns about privacy and security. To address security issues, city-centric services are shifting towards blockchain-based systems, which is a time-consuming and challenging process. This paper proposes an interoperability framework for blockchain-based smart city services and explores how independent service providers can continue local transactions without overloading the blockchain network. A simulated interoperability network demonstrates the effectiveness of the framework, showcasing the scalability and memory optimization of the blockchain network.
The widespread usage of smart devices with various city-centric services speeds up and improves civic life, in contrast to growing privacy and security concerns. Security issues are exacerbated when e-government service providers trade their services within a centralised framework. Due to security concerns, city-centric centralised services are being converted to blockchain-based systems, which is a very time-consuming and challenging process. The interoperability of these blockchain-based systems is also more challenging due to protocol variances, an excessive amount of local transactions that raise scalability and rapidly occupy memory. In this paper, we have proposed a framework for interoperability across various blockchain-based smart city services. It also summarises how independent service providers might continue self-service choices (i.e., local transactions) without overloading the blockchain network and other organisations. A simulated interoperability network is used to show the network's effectiveness. The experimental outcomes show the scalability and memory optimization of the blockchain network.
