The secure transmission of communication data between different devices still faces numerous potential challenges, such as tampering, integrity, network attacks, and the risks information leakage or forgery. This approach aims to handle distributed trust issues federated learning users update states rapidly. By modeling multi-source through learning, model parameters reputation values participating are stored on blockchain. method incorporates factors experience, familiarity, timeliness more quickly gather reliable about nodes assess their behavior. Simulation results MNIST dataset show that when proportion selfish is below 50%, convergence time increases with nodes. Compared advanced algorithms, proposed saves approximately 6% interaction time. As number transactions significantly increases, system's TPS (Transactions Per Second) decreases, an average only 3079.35 maximum 4000. scheme can filter out high-quality sources during real-time dynamic exchange, enhancing accuracy training ensuring privacy security.

Aiming at the problems of significant communication overheads, low reliability primary nodes, and insufficient dynamic adaptability traditional consensus algorithms in intellectual property transaction scenarios, an Improved Practical Byzantine Fault Tolerant (IPBFT) algorithm based on Chord entropy weight method is proposed. Firstly, employed to map nodes onto a hash ring, enabling grouping. Secondly, entropy-based reputation model constructed, quantifying evaluation node behaviors calculating overall value. A three-level classification mechanism used dynamically select supervisory thereby reducing probability being elected. Then, three-phase monitoring strategy for developed, which includes collection, review, blackout. This improves Raft process, enhancing detection fault tolerance against malicious leaders. Finally, grouped dual-layer architecture The lower layer uses improved efficient within groups, while upper PBFT cross-group global consistency verification. Experimental findings demonstrate that IPBFT able balance security, scalability, efficiency network environment, providing better solution transactions.

Blockchain technology uses a consensus mechanism to create and finalize blocks. The affects the total performance parameters of blockchain network, such as throughput. In this paper, we present “Nazfast”, simplified proof stake—Byzantine fault tolerance based presented is completed in multiple folds. For block producer validation committee selection, used secure speeded-up election mechanism, S&Sem, Nazfast. designed for fast finalization malicious environment. simulation result shows that approximately achieved three finalizations 1 s with almost similar latency. We reduced fixed number validators improve higher throughput among other same family. Because validators, safety are at risk, so Sea Shield overall safety. This another save nodes’ details when they join/unjoin network validators. By using all parts together, our system protected from 28-plus different attacks, maintain high decentralization by S&Sem. Finally, also enhance incentive liveness network.
