Abstract

Blockchain technology has become a trusted method for establishing secure and transparent transactions through a distributed, encrypted network. The operation of blockchain is governed by consensus algorithms, among which Proof of Stake (PoS) is popular yet has its drawbacks, notably the potential for centralising power in nodes with larger stakes or higher rewards. Our proposed novel solution, Fuzzychain, leverages fuzzy sets to define stake semantics, introducing a degree of softness in validator selection. This approach mitigates rigid threshold-based decision-making by allowing gradual transitions between stake levels, reducing sharp disparities among validators. By incorporating this enhanced stake evaluation, Fuzzychain promotes a more adaptive and distributed selection process, ensuring a fairer and more inclusive blockchain network. A thorough assessment of a real-time multi-agent blockchain system to examine validator selection and reduce inequality, promoting a more equitable distribution of stakes among validators compared to other consensus mechanisms. This fosters a more inclusive selection process and a more equitably distributed network.

模糊链：区块链网络的公平共识机制

区块链技术已经成为通过分布式加密网络建立安全透明交易的可靠方法。区块链的操作由共识算法管理，其中权益证明（PoS）很受欢迎，但也有其缺点，特别是在拥有更大赌注或更高奖励的节点上集中权力的潜力。我们提出的新解决方案Fuzzychain利用模糊集来定义利害关系语义，在验证器选择中引入一定程度的柔软性。这种方法通过允许利害关系级别之间的逐渐转换，减少验证者之间的急剧差异，减轻了基于阈值的严格决策。通过整合这种增强的利益评估，模糊链促进了一个更具适应性和分布式的选择过程，确保了一个更公平、更包容的区块链网络。对实时多代理区块链系统进行全面评估，以检查验证者的选择并减少不平等，与其他共识机制相比，促进验证者之间更公平的利益分配。这促进了一个更具包容性的选拔过程和一个更公平分配的网络。
