The timeliness of shared data is one of the important factors affecting efficient collaboration among smart factories (SFs). Although the blockchain-based edge computing data sharing scheme has achieved certain results in data sharing efficiency and security, the pbft consensus algorithm widely used in the industrial Internet of Things (IIoT) still faces the problems of large communication overhead, single selection of master nodes, and lack of processing of malicious nodes. In order to solve the above problems, we propose a secure and efficient intelligent grouping pbft (IG-pbft) consensus algorithm for the industrial internet of things. First, we design and implement the consensus group intelligent construction method, divide the simulated SF into different consensus groups, and reduce the communication overhead of the blockchain network through two consensus processes within and among the consensus groups. Then, we propose a group leader smart factory intelligent selection method, which selects a SF for each consensus group based on the trust degree of the SF, and the SF represents the consensus group to participate in the consensus among the consensus groups, which improves the security of the blockchain network. Then, we design and implement a constrained smart factory intelligent labeling method that labels SFs based on the category of SFs in the current consensus cycle to prevent constrained SFs from participating in the consensus process. Finally, we conducted simulation experiments on the IG-pbft consensus algorithm. Through theoretical and simulation experiments, it is proven that the IG-pbft consensus algorithm can reduce the communication overhead of the traditional pbft consensus algorithm, improve the security of the consensus process, and have obvious advantages in the IIoT.

Metaverse is a visually rich virtual space in which users can interact with each other. By introducing metaverse into vehicular networks, vehicular metaverse can provide users real-time immersive experiences based on augmented technologies. Vehicular edge computing is a desirable approach to support computation-intensive vehicular metaverse services by network resource collaboration. User collaboration needs to reach a consensus on perception information, operation control and so on to realize user autonomy. However, the existing consensus algorithms often require computational proof or frequent communication, making them unsuitable for dynamically changing vehicular edge metaverse with low latency and energy restrictions. In this paper, we have proposed a reputation model maintained in the vehicular edge metaverse to score the vehicles, so the vehicles with a high reputation can be selected to participate in practical Byzantine fault tolerant (pbft) consensus, which improves the probability of success and credibility of consensus without increasing the number of participating vehicles. Meanwhile, an optimization problem is formulated for each vehicle to allocate its computation and communication resources to reach a pbft consensus. Also, the optimized communication time interval of each phase in the pbft consensus can be used as a reference for setting the agreed upper time, which reduces the waiting time of vehicles and the probability of re-consensus. Simulation results have demonstrated that the proposed scheme effectively achieves pbft information consensus with lower latency and energy consumption, and thus is more scalable and efficient.

In order to manage human resource information safely and effectively, this paper studies the human resource management model based on blockchain technology. The client node obtains the human resource information through the intelligent terminal, submits it to the SDK access node, encrypts and signs it with the encryption algorithm, and then transmits it to the blockchain network. The consistency node of the blockchain network uses the improved practical byzantine fault tolerance (pbft) consistency algorithm to pack the information into blocks, complete the charging process and broadcast it to the master node. The master node broadcasts the billing copy to the storage node to complete the secure storage of human resource information. The experimental results show that the model has advantages in human resource information encryption, submission and new user identity authentication. The model provides guarantee for the effective implementation of human resource management.

In the fire scene investigation, the firefighting Internet of Things (IoT) data is the key electronic evidence for event analysis and responsibility determination. However, the traditional centralized storage method leads to data easy to be tampered with and damaged. To solve these problems, this paper designs and implements a secure, reliable and low-cost distributed firefighting IoT data storage scheme based on the Fabric framework, combining blockchain technology, Interplanetary File System (IPFS) and Practical Byzantine Fault Tolerance (pbft) consensus algorithm to provide a strong support for fire accident traceability. This scheme mainly includes the storage model, key algorithms and Fabric construction and improvement. IPFS stores the complete firefighting IoT data, as the off-chain storage system of the blockchain, and the blockchain only stores the storage address (IPFS hash) of data returned by IPFS, thus reducing the storage space overhead of the blockchain and ensuring data security. Further, we adopt the Fabric framework as the blockchain platform for firefighting IoT data, and embed the pbft consensus algorithm into the framework to ensure the reliability of consensus nodes in Fabric, thus improving the availability of the blockchain. In addition, we use the AES and RSA algorithms to ensure the security of firefighting IoT data storage and transmission. Through system analysis and experimental testing, the proposed scheme meets the need for secure storage and traceability of firefighting IoT data. Compared with the storage scheme using only blockchain, the blockchain combined with IPFS technology has advantages in storage space occupation, significantly improved throughput, and lower latency overhead. Meanwhile, compared with the official Fabric, the improved Fabric supports Byzantine fault tolerance and has better security.

The main study focuses on the shortcomings of the traditional pbft consensus algorithm and the DPOS consensus algorithm, and then combines the two algorithms to form a new consensus algorithm from the perspective of optimising the consensus performance of the blockchain, which can achieve several advantages in terms of node reduction view switching, node dynamics, bandwidth overhead reduction, transaction throughput and lower system latency performance. The advantages of the improved pbft algorithm are illustrated by the experimental data on throughput, system latency of account creation and bandwidth overhead, which are compared to illustrate the effect of the improved pbft algorithm.

The consortium blockchain has three challenges in terms of performance, security, and privacy when adopting the Practical Byzantine Fault Tolerance (pbft) protocol. The throughput and scalability of consortium blockchain are focused on meanwhile the privacy protection can hardly be ignored. This work proposes a privacy-preserving multi-signature and hierarchical Byzantine consensus protocol. Specifically, the signature combines a ring signature and a Schnorr one to provide three levels of privacy protection. The consensus protocol layers the network nodes into different clusters, which overcomes the shortcomings of pbft and Schnorr signature. The theoretical analysis proves the security and privacy of the protocol and expounds the application scenarios, and the efficiency evaluation shows that the signature verification speed is 6.28 times faster than the Schnorr scheme, and the consensus in a 250-nodes network is 51.3% faster than the Schnorr-based pbft consensus.

Today, the manner in which we communicate has greatly advanced. The technology is not just about machines, but people with technology together. Machine-to-machine (M2M) communication is unavoidable in the Internet of things. However, at the same time, there are more attacks against the M2M system. Therefore, a reliable and secure authentication mechanism is required. Blockchain technology is decentralized and highly secure while being tamper-proof. This protects M2M service providers by eliminating the single point of failures. This paper proposes a blockchain-based authentication scheme that uses a practical Byzantine fault tolerance (pbft) consensus mechanism for M2M security in cyber physical systems. By implementing a blockchain to an M2M system, it provides an ID for devices on the blockchain. Simulation results have shown that the data on the chain cannot be altered. A pbft consensus algorithm also ensures that the blockchain network is able to come to a consensus with faults.

To solve the credibility and supervision lacking problem in the OTC warehouse receipt trading system, a scheme of using smart contract on the blockchain to implement the OTC warehouse receipt trading system is presented. As a distributed ledger, blockchain has the advantages of decentralization, irreversibility and trustworthiness. The warehouse receipt transaction data is recorded on the blockchain, ensuring its safety and credibility. Smart contract is automatically executed code stored on the blockchain, it can directly control the transaction of digital assets. No participant can control and tamper it before the contract is lapsed. In the process of using the Ethereum smart contract to realize warehouse receipt transactions, consensus is reached by the pbft consensus algorithm, Since the trusted third-party is not needed, the lack of supervision problem is solved. This paper introduces the application of blockchain and smart contract to the OTC warehouse receipt trading system. It includes the design of smart contracts, the verification of smart contracts security. This paper also verifies the feasibility of designing smart contracts by using the instance of listed transactions.
