“…The nodes from 6 to 10 have mean block transaction rates of 24, 27.14, 24.14, 30.71, and 27.14 blocks per second, respectively. Also, from the 11th node to the 15th node, the mean block transaction rates were recorded as 24.14, 26.71, 23.71, 35.14, and 30.5 blocks per second, respectively [45]. Also, as per the results shown in Figure 19, the block transaction rate of the network with fifteen Duino coin blockchain nodes has a deviation from 10 to 50 blocks per second.…”

With the development of Internet of Things (IoT) technologies, industries such as healthcare have started using low-powered sensor-based devices. Because IoT devices are typically low-powered, they are susceptible to cyber intrusions. As an emerging information security solution, blockchain technology has considerable potential for protecting low-powered IoT end devices. Blockchain technology provides promising security features such as cryptography, hash functions, time stamps, and a distributed ledger function. Therefore, blockchain technology can be a robust security technology for securing IoT low-powered devices. However, the integration of blockchain and IoT technologies raises a number of research questions. Scalability is one of the most significant. Blockchain’ scalability of low-powered sensor networks needs to be evaluated to identify the practical application of both technologies in low-powered sensor networks. In this paper, we analyse the scalability limitations of three commonly used blockchain algorithms running on low-powered single-board computers communicating in a wireless sensor network. We assess the scalability limitations of three blockchain networks as we increase the number of nodes. Our analysis shows considerable scalability variations between three blockchain networks. The results indicate that some blockchain networks can have over 800 ms network latency and some blockchain networks may use a bandwidth over 1600 Kbps. This work will contribute to developing efficient blockchain-based IoT sensor networks.

“…In recent years, blockchain technology has been widely used as a decentralized data storage system. By removing all central servers and achieving peer-to-peer interaction between all network nodes [6] , it can provide a solution for the storage and sharing of user data in IoT with traceability, tamper-proof, and unforgeability. Blockchain-based privacy protection for IoT will result in a significant improvement in data security, where users' data are recorded in a decentralized ledger and it is difficult for hackers to tamper with the ledger to overwrite the existing data [7,8].…”

In the era of big data, an ocean of data generated by Internet of Things (IoT) devices will be analyzed and processed by cloud computing. However, outsourcing of data can lead to leakage of user privacy to those unreliable service providers. In this paper, we propose a novel privacy-preserving scheme for IoT device by employing privacy set intersection (PSI) and blockchain technique to achieve data privacy. First, a homomorphic encryption PSI technique based on 0-1 encoding is proposed, which well hides the set base to ensure data privacy. Second, combining blockchain structure and smart contract, the proposed scheme can improve the efficiency of data sharing by storing the shared data on a blockchain. Third, the security analysis shows that the scheme has extremely high control over the individual data and can ensure the security and privacy of the data. Finally, we compare the functionality with other relevant schemes and demonstrate that our scheme functions well with low communication and computational overhead.
