摘要

本文介绍了EVONChain,这是一种受自然启发的可进化区块链,用于解决大规模区块链应用中的可扩展性问题。EVONChain将完整区块链节点的功能解耦为两个共识阶段。内部网络中的少数高性能云节点使用“最长链”规则处理事务验证、块打包和一致复制。与此同时,外部网络中由移动边缘计算(MEC)提供商连接的大量低性能用户节点处理智能证明(PoI),这是一种新颖的工作量证明(PoW)机制,可以抵抗专用集成电路(ASIC)计算,并实现“一cpu一票”原则。这种架构使EVONChain能够实现完美的去中心化、高扩展性和安全性。为了评估EVONChain的性能,我们开发了一个模拟器。仿真结果表明,EVONChain在内部网络带宽为4Gbps、块间隔为10秒、孤立块率小于7%的情况下,可以实现每秒10000笔交易(TPS)以上的吞吐量。这表明EVONChain显著提高了高频应用的性能可扩展性,将确认时间缩短到分钟级别,同时保持了与以太坊网络相当的安全级别。

EVONChain: A Public Blockchain Architecture with Bi-tiered Network for Edge Computing
This paper introduces EVONChain, a nature-inspired evolvable blockchain that addresses scalability issues in large-scale blockchain applications. EVONChain decouples the functions of a full blockchain node into two consensus phases. A small number of high-performance cloud nodes in the inner network handle transaction validation, block packaging, and consistent replication using the “longest chain” rule. Meanwhile, a large number of low-performance user nodes connected by Mobile Edge Computing (MEC) providers in the outer network handle the Proof of Intelligent (PoI), a novel Proof of Work (PoW) mechanism that resists Application-Specific Integrated Circuit (ASIC) computing and enables “one-CPU-one-vote” principle. This architecture enables EVONChain to achieve perfect decentralization, high scalability and security. To evaluate EVONChain’s performance, we developed a simulator. Simulation results show that EVONChain can achieve a throughput of over 10,000 transactions per second (TPS) with an inner network bandwidth of 4Gbps, a block interval of 10 seconds, and an orphaned block rate of less than 7%. This indicates that EVONChain significantly improves performance scalability for high-frequency applications, reduces confirmation time to the minute level, while maintaining a comparable level of security to the Ethereum network.
