# 2.4.3 作为状态通道的Fuel (Fuel as a state channel)

### 定义状态通道 (Defining State Channels)

A state channel is a smart contract that enforces off-chain transactions between predefined parties. Each transaction updates the state of the chain and is cryptographically provable on-chain.

状态通道是一种智能合约，能够在预先定义的各方之间执行链下交易。每笔交易都会更新链的状态，并且可以在链上进行加密证明。

### Fuel 作为状态通道 (Fuel as a State Channel)

The FuelVM is a priced virtual machine architecture with a deterministic state system, which makes it perfect for multi-party channel designs where all parties must have clarity over the exact state of the system at each communication step or window.

FuelVM 是一种具有确定性状态系统的定价虚拟机架构，这使得它非常适合多通道设计，在这种设计中，所有各方都必须清楚系统在每个通信步骤或窗口的确切状态。

While we do not ship a channel configuration of the Fuel technology out of the box, the FuelVM is perfectly situated to handle this particular use case.

虽然我们没有开箱即用地提供 Fuel 技术的通道配置，但 FuelVM 非常适合处理这种特殊用例。
