Abstract

Blockchain technology, renowned for its decentralized and secure nature, has gained substantial attention. Central to its functionality are consensus mechanisms, which are essential for validating transactions and upholding the integrity of the distributed ledger. However, the efficiency and scalability of blockchain are currently impeded by the resource limitations and excessive communication demands of existing consensus mechanisms. To address these challenges, we propose GT-BFT, a streamlined and lightweight blockchain consensus mechanism grounded in a global trust model. This model capitalizes on node behavior to form consensus groups and facilitate consensus achievement. GT-BFT integrates a novel approach of selective broadcasting along with a Byzantine threshold determination algorithm, significantly boosting both the efficiency and security of the network. Our extensive analysis and performance evaluation reveal that GT-BFT surpasses existing mechanisms in key areas such as security, system throughput, and transaction confirmation speed, marking a significant advancement in blockchain consensus technology.

基于全局信任的区块链轻量级共识机制

区块链技术以其去中心化和安全性而闻名，已经获得了大量的关注。其功能的核心是共识机制，这对于验证交易和维护分布式账本的完整性至关重要。然而，区块链的效率和可扩展性目前受到现有共识机制的资源限制和过多的通信需求的阻碍。为了应对这些挑战，我们提出了GT-BFT，这是一种基于全球信任模型的精简轻量级区块链共识机制。该模型利用节点行为来形成共识组并促进共识的实现。GT-BFT集成了一种新的选择性广播方法以及拜占庭阈值确定算法，显着提高了网络的效率和安全性。我们广泛的分析和性能评估表明，GT-BFT在安全性、系统吞吐量和交易确认速度等关键领域超越了现有机制，标志着区块链共识技术的重大进步。
