2.3.4 什么是模块化执行层 (What is a Modular Execution Layer)

In addition to the properties of a rollup, a modular execution is different because it also has these two additional properties:

除了汇总的属性之外，模块化执行是不同的，因为它还具有以下两个附加属性：

• With a modular execution layer, users can run an off-chain light client, allowing users to validate the chain without running a full node. 通过模块化执行层，用户可以运行链下轻客户端，允许用户在不运行完整节点的情况下验证链。

• A modular execution layer is not tightly coupled to a specific layer 1, allowing for greater flexibility. 模块化执行层与特定第 1 层不紧密耦合，从而提供更大的灵活性。

轻客户端 (Light Clients)

One of the core characteristics of a modular execution layer is related to the trust model of the system. A modular execution layer has all the properties of a rollup, and the ability to run a light client. This allows you to have trust-minimized infrastructure. Read more about light clients here.

模块化执行层的核心特征之一与系统的信任模型有关。模块化执行层具有汇总的所有属性，以及运行轻客户端的能力。这使您可以拥有最小化信任的基础架构。查看 此处 详细了解轻客户端。

灵活性 (Flexibility)

Another core property of a modular execution layer is that it is not tightly coupled to a specific layer 1. This offers flexibility that allows Fuel to be deployed. Read more about Fuel's flexibility here.

模块化执行层的另一个核心属性是它不与特定的第 1 层紧密耦合。这提供了允许部署 Fuel 的灵活性。点击 此处 详细了解 Fuel 的灵活性。
