EZchain的性能、安全和去中心化分析 六、 EZchain 模拟实验 七、结论、认可和参考 —The development of underlying technologies in blockchain mostly revolves around a difficult problem: how to enhance the performance of the system and reduce various costs of nodes (such as communication, storage and verification) without compromising the system’s security and decentralization. Various layer-1 and layer-2 protocols have provided excellent solutions for this challenge. However, they cannot yet be considered as a “silver bullet”. This paper proposes EZchain—a novel decentralized “scale-out” ledger system designed for web3.0, aiming to enable blockchain technology to truly support ledger applications in large-scale fully decentralized networks. Without compromising security and decentralization, EZchain successfully accomplishes the following milestones: 1) Scalability: The theoretical throughput of EZchain can be infinitely expanded, nearly unaffected by bandwidth and other resource constraints. 2) Consumer-Grade Hardware Compatibility: EZchain is designed to be compatible with consumer-grade hardware, supporting storage, computation, and verification requirements. 3) Efficient Transaction Confirmation: EZchain strives to maintain transaction confirmation delays within one minute. Our prototype experiment demonstrates that under typical daily bandwidth network conditions, EZchain’s performance in all aspects approaches that of the accounts in centralized payment systems. This provides a solid infrastructure for realizing mobile payments in web3.0. Abstract 抽象 一、介绍 在区块链应用中,在不牺牲去中心化和安全的情况下实现Web2.0的中央服务器级性能一直是关键的瓶颈,也被称为区块链不可能的三角形。 关于上述挑战,在本文中我们介绍了EZchain,一个区块链解决方案,其特点是其高性能、去中心化和强大的安全性。不同于假设去中心化、二层和离链概念,EZchain严格遵守去中心化原则,实现一层性能突破。

 Uncompromised security and decentralization. EZchain实施了一种开创性的共识算法,旨在最大限度地减少共识、传输和存储信息。它引入了一种新的数据结构,“价值”,与比特币或账户平衡模型中的UTXO模型不同。我们所知道的数据结构和算法的这种独特组合代表了区块链可扩展性领域的前所未有的方法。对于EZchain的出色表现,其基本理由在于“价值”数量的相对稳定性,而不是不断增加的交易量。关注价值转移的这种转变提供了独特的优势和优化策略。
