2.4.1 作为汇总的Fuel (Fuel as a roll-up)

定义汇总 (Defining Rollups)

A layer-2 is a term used to describe a set of scaling solutions. A rollup is an off-chain network built on top of the layer-1 that executes transactions off-chain, bundles these transactions, and posts the bundled transactions as a single transaction on the layer-1 chain.

第 2 层(L2)是用于描述一组扩展解决方案的术语。汇总是建立在 layer-1 之上的链下网络，它执行链下交易，捆绑这些交易，并将捆绑的交易作为单个交易发布在 layer-1 链上。

Fuel 作为汇总或 Layer-2 (Fuel as a Rollup or Layer-2)

Fuel is designed to run a modular execution layer, a configuration similar to what we call rollups or layer-2s on Ethereum today. Rollups typically use an optimistic or zk-configuration for validity or transaction arbitration. The Fuel technology is agnostic to either of these and can utilize either as a validity or fraud-proving system.

Fuel 意在运行模块化执行层，这种配置类似于我们今天在以太坊上所说的汇总或第 2 层。汇总通常使用OP 或 zk 配置来进行有效性或交易仲裁。 Fuel 技术对其中任何一个都是跨平台的，并且可以用作有效性或欺诈证明系统。

Layer-2s and rollups are primarily designed for monolithic blockchain stacks, which means they are typically not optimized for large amounts of layer-1 bandwidth potential unlike Fuel, which is uniquely configured to handle this potential.

Layer-2 和 汇总主要是为单片区块链堆栈设计的，这意味着它们通常没有针对大量的 layer-1 带宽潜力进行优化，这与 Fuel 不同，Fuel 是为处理这种潜力而特殊配置的。
