Abstract:

With the rapid development of Ethereum, archive nodes that record all historical states have become a critical component of the infrastructure. However, current archive nodes suffer enormous storage requirements and poor performance due to the inefficient authenticated Merkle Patricia Trie and coarse-grained state granularity. This paper presents a lightweight and high-performance architecture for Ethereum archive nodes to address the two limitations mentioned earlier. The core idea of our approach is to maintain compacted, flattened, and fine-grained (i.e., transaction-level) historical states by flattening the minimum state changes of each transaction required for the world state. Our method maintains an archive node with minimum storage requirements while providing high-performance state access. We have implemented a prototype system named SLIMARCHIVE for Ethereum. The evaluation results demonstrate that our approach reduces storage requirements by 98.1%, improves state access throughput by 19.0×, and speeds up transaction execution by an average of 1112.5×, compared to vanilla Geth.

随着以太坊的快速发展，记录所有历史状态的档案节点已成为基础设施的重要组成部分。然而，由于认证 Merkle Patricia Trie 效率低下和状态粒度粗，当前的档案节点面临着巨大的存储需求和糟糕的性能。

本文提出了一种轻量级、高性能的以太坊档案节点架构，以解决前面提到的两个限制。我们方法的核心思想是通过扁平化世界状态所需的每笔交易的最小状态变化来维护紧凑、扁平和细粒度（即交易级别）的历史状态。我们的方法维护一个具有最低存储要求的存档节点，同时提供高性能的状态访问。我们为以太坊实现了一个名为 SLIMARCHIVE 的原型系统。评估结果表明，与 vanilla Geth 相比，我们的方法将存储要求降低了 98.1%，将状态访问吞吐量提高了 19.0 倍，并将交易执行速度平均提高了 1112.5 倍。
