A Hypergraph-Based Blockchain Model and Application in Internet of Things-Enabled Smart Homes

Abstract

With the fast development and expansion of the Internet of Things (IoT), billions of smart devices are being continuously connected, and smart homes, as a typical IoT application, are providing people with various convenient applications, but face security and privacy issues. The idea of Blockchain (BC) theory has brought about a potential solution to the IoT security problem. The emergence of blockchain technology has brought about a change of decentralized management, providing an effective solution for the protection of network security and privacy. On the other hand, the smart devices in IoT are always lightweight and have less energy and memory. This makes the application of blockchain difficult. Against this background, this paper proposes a blockchain model based on hypergraphs. The aims of this model are to reduce the storage consumption and to solve the additional security issues. In the model, we use the hyperedge as the organization of storage nodes and convert the entire networked data storage into part network storage. We discuss the design of the model and security strategy in detail, introducing some use cases in a smart home network and evaluating the storage performance of the model through simulation experiments and an evaluation of the network.

Simulation Model for Blockchain Systems Using Queuing Theory

“…Recently, blockchains have received tremendous attention from several researchers. The emergence of blockchain technology in the form of digital currencies has influenced many other fields such as e-healthcare, e-finance, real estate, e-voting, supply chains, Smart homes, Smart cities, Smart Industries, the Internet of Things, and so forth [3][4][5][6]. The popularity of blockchains is natural, as they have the potential to provide desirable features by replacing centralized communication architectures.…”

Adoption of blockchain technology in various realms: Opportunities and challenges

“…Xu et al 57 proposed blockchain-enabled decentralized federated capability-based access control model that employs smart contract and blockchain technology for enhancing the access control in IoT. Qu et al 58 proposed the hyperedge model that is based on hypergraphs for improving the scalability efficiency in smart devices of IoT. Zhu et al 59 suggest a controllable data management blockchain system for improving cloud data management so that it assists in enhancing the weakened network capability and overcoming 51% attack.…”

The Application of Blockchain-as-a-Service (BaaS) and its providers in China

“…Blockchain can also contribute to the equity crowdfunding in China because it is an efficient and low-cost solution for registration and has the ability to simplifying the transaction procedure while guaranteeing the transparency of information [6]. For IoT, blockchain can bring decentralized management and thus connects billions of smart devices, leading us into the age of smart homes [7]. In the energy field, the decentralized feature of blockchain reduces the entry threshold for the carbon trading market, and the future of this integration is promising [8].…”
