论文摘要
“无国籍以太坊”的概念是以减轻以太坊无限国家增长的主要目的。无国籍以太坊的主要促进者是通过将“证人”引入生态系统。需要确定和分析这些附加数据包在网络上构成的变化和潜在后果，以确保以太坊生态系统可以继续安全有效地运行。在本文中，我们提出了一种贝叶斯网络模型，一种概率的图形建模方法，以捕获以太坊主网中的关键因素及其相互作用，即公共以太坊区块链，重点关注无状态以太坊引入的变化，以估算所得的以太坊生态系统的健康。我们使用经验数据和专家知识的混合物（在数据不可用的地方）来量化模型。根据建模时可用于使用的数据和专家知识，在引入无状态以太坊后，以太坊生态系统预计将保持健康。
The concept of 'Stateless Ethereum' was conceived with the primary aim of mitigating Ethereum's unbounded state growth. The key facilitator of Stateless Ethereum is through the introduction of 'witnesses' into the ecosystem. The changes and potential consequences that these additional data packets pose on the network need to be identified and analysed to ensure that the Ethereum ecosystem can continue operating securely and efficiently. In this paper we propose a Bayesian Network model, a probabilistic graphical modelling approach, to capture the key factors and their interactions in Ethereum mainnet, the public Ethereum blockchain, focussing on the changes being introduced by Stateless Ethereum to estimate the health of the resulting Ethereum ecosystem. We use a mixture of empirical data and expert knowledge, where data are unavailable, to quantify the model. Based on the data and expert knowledge available to use at the time of modelling, the Ethereum ecosystem is expected to remain healthy following the introduction of Stateless Ethereum.
