“…The voting tendency of nodes can also be considered by referring to the decision-making behaviors of human beings in real life. For example, vague set (Xu et al , 2020), Pythagorean fuzzy sets (PFSs) (Lin et al , 2021b) and probabilistic linguist term set (PLTS) (Liu et al , 2021b; Chen et al , 2021b; Xu et al , 2021a; Li et al , 2021b; Liang et al , 2020; Lin et al , 2018a, b, 2019a, b, 2020, 2021a) are introduced in the election of delegates in the DPoS consensus mechanism. Similarly, a node mutual evaluation strategy can be designed to rank and remove consensus nodes promptly, thus making voting more efficient.The improvement of the effectiveness of cross-sharding consensus.…”

PurposeAs the core technology of blockchain, various consensus mechanisms have emerged to satisfy the demands of different application scenarios. Since determining the security, scalability and other related performance of the blockchain, how to reach consensus efficiently of consensus mechanism is a critical issue in the blockchain.Design/methodology/approachThe paper opted for a research overview on the blockchain consensus mechanism, including the consensus mechanisms' consensus progress, classification and comparison, which are complemented by documentary analysis.FindingsThis survey analyzes solutions for the improvement of consensus mechanisms in blockchain that have been proposed during the last few years and suggests future research directions around consensus mechanisms. First, the authors outline the consensus processes, the advantages and disadvantages of the mainstream consensus mechanisms. Additionally, the consensus mechanisms are subdivided into four types according to their characteristics. Then, the consensus mechanisms are compared and analyzed based on four evaluation criteria. Finally, the authors summarize the representative progress of consensus mechanisms and provide some suggestions on the design of consensus mechanisms to make further advances in this field.Originality/valueThis paper summarizes the future research development of the consensus mechanisms.

“…In the study of certificate encryption, we have proposed a certificateless blockchain‐oriented cryptographic mechanism that not only improves the security of certificateless encryption but also reduces the storage overhead, but the computational overhead brought by the introduction of blockchain to the certificateless encryption mechanism needs to be further optimized 17 . In terms of ring signature, Li et al 18 applied permission management mechanisms and linkable‐for‐signature to blockchain voting modules, which can protect block data privacy during the voting phase, but the introduction of proxy nodes in this scheme increases the centralization of the system, and its resistance to attack needs to be improved.…”

As a distributed ledger technology, blockchain has excellent openness and transparency, which can provide data security management services for distributed intelligent systems and establish effective security guarantee mechanisms. However, precisely due to the open nature of blockchain, malicious users can trace the real transaction transfer path with high probability and even obtain the real identity of users by collecting transaction information on the blockchain and performing data analysis. Besides, existing intelligent systems lack effective encryption or desensitization measures, and attackers are able to access data in intelligent systems through identity forgery and other means, posing a huge potential risk to user privacy. To alleviate the above security issues, this paper proposes an efficient blockchain‐based privacy‐preserving scheme with attribute and homomorphic encryption, which can not only achieve user‐level fine‐grained secure access control but also supports the transmission and verification of blockchain data in the form of ciphertext. The access control method based on attribute‐based encryption and the data transmission method based on homomorphic encryption are proposed, and the blockchain‐based access whitelist mechanism is designed to reduce the resource loss due to repeated authentication. Simulation calculations and blockchain performance experiments show that this scheme can develop flexible access policies according to the attributes of users, has good performance in computational efficiency, and the blockchain performance test results are stable with errors in milliseconds for all operations. It has certain application potential in the field of distributed intelligent systems and blockchain.

This study proposes a primary node election method based on probabilistic linguistic term set (PLTS) for the practical Byzantine fault tolerance (PBFT) consensus mechanism to effectively enhance the efficiency of reaching consensus. Specifically, a novel concept of the probabilistic linguistic term set with a confidence interval (PLTS-CI) is presented to express the uncertain complex voting information of nodes during primary node election. Then, a novel score function based on the exponential semantic value and confidence approximation value for the PLTS-CI, called Score-ESCA, is used to solve the problems of comparing different nodes with various voting attitudes. This method helps select the node with the highest score by utilizing complex decision attitudes, making it an accurate primary node election solution. Furthermore, the feasibility of our proposed method is proved by both theoretical analysis and experimental evaluations.
