Welcome to Inside Fuel, our review of the technical developments on the Fuel Network. Take a moment to catch up with all of the latest news.

欢迎来到 Inside Fuel，这是我们对 Fuel网络技术发展的回顾。欢迎您拨冗了解所有最新消息。

Fuelup简介 (### Introducing Fuelup)

什么是Fuelup (What is Fuelup?)

Fuelup is the official package manager and multiplexer for Fuel that installs The Fuel Toolchain from the official release channels. It enables you to easily install pre-packaged toolchains, keep them up to date or even create custom toolchains and switch between them.

Fuelup 是 Fuel 的官方包管理器和复用器，它从官方发布渠道安装Fuel工具链 (The Fuel Toolchain)。它使您能够轻松安装预打包的工具链，使其保持最新状态，甚至创建自定义工具链并在它们之间切换。

Binaries are executed through Fuelup as proxies which allow for flexibility in the execution of tools.

二进制文件通过 Fuelup 作为代理执行，使得工具的执行变得灵活。

It simplifies building and maintaining Sway applications with forc and fuel-core for common platforms.

它为一般平台使用 forc 和 fuel-core 简化了 Sway 应用的构建和维护。

Right now, fuelup has the latest toolchain as the only pre-packaged official toolchain. Components in this toolchain are tested for compatibility in our GitHub CI before being updated. For more flexibility at the cost of possible incompatibility or instability, advanced users can specify specific versions of components they want to install and use.

目前，fuelup 拥有 latest 工具链，也是唯一预打包的官方工具链。此工具链中的组件在更新之前在我们的 GitHub CI 中进行了兼容性测试。以可能的不兼容或不稳定为代价，获得了更大的灵活性，高级用户可以指定他们想要安装和使用的特定版本的组件。

Basic usages such as keeping the toolchain or Fuelup up to date can be found here.

可以在此处找到基本用法，例如使工具链或保持更新 Fuelup 。

For more details on how Fuelup works, as well as usage examples, please refer to The Fuelup Book.

有关 Fuelup 工作原理的更多详细信息以及用例，请参阅 The Fuelup Book。

Note that Fuelup is still in active development with more features soon to come. Opening issues for any bugs, or suggestions to improve it are welcome.

请注意，Fuelup 仍在积极开发中，即将推出更多功能。欢迎指出任何错误，提出意见或建议。

Swap应用 (Sway Applications)

Sway应用存储库 (The Sway Applications Repository)

The purpose of the Sway Applications repository is to demonstrate what can be built with Sway and to promote good development practices.

Sway 应用存储库的目标是，演示可以使用 Sway 构建什么并激发优秀的开发实践。

That being said, the repository should be deemed as a living project since the applications will be actively maintained, and thus it is likely that none of them will ever reach their final form!

也就是说，存储库应该被视为一个活的项目，因为应用将被积极维护，因此很可能它们都不会达到最终形式/一直更新！

The repository is young so there isn't anything for anyone to use yet, however, we have lots of applications in development, and lots more planned to be worked on in the near future.

存储库还很年轻，所以还没有任何东西可供任何人使用，但是，我们有很多应用正在开发中，并且计划在不久的将来进行更多工作。

So far, the applications are planned to have a smart contract to demonstrate Sway, tests written in Rust to demonstrate the Rust-SDK, and a user interface to demonstrate the use of the Typescript-SDK.

到目前为止，这些应用计划有一个智能合约来演示 Sway，用 Rust 编写的测试来演示 Rust-SDK，以及一个用户界面来演示 Typescript-SDK 的使用。

That isn't to say that you cannot have a CLI application, a plugin, or any other type of app. Those are simply not in development at the moment.

这并不是说您不能拥有 CLI 应用程序、插件或任何其他类型的应用。只是说这些目前根本不在开发中。

This part presents the applications that have gone through some level of scrutiny and have been deemed acceptable to be merged into the master branch.

这部分介绍了经过一定程度审查并被认为可以合并到主分支中的应用。

NOTE
This does not mean that they are complete nor that development has ceased.

注意
这并不意味着它们是完整的，也不意味着开发已经停止。

全新的DAO智能合约原型 (New DAO Smart-Contract prototype)

DAO是什么? (What is a DAO?)

A decentralized autonomous organization (DAO) is akin to an on-chain government where participants are able to cast votes on proposals using some governance token. Various consensus mechanisms may be implemented in order to determine whether a proposal will pass and if that happens then the DAO will begin to operate under the rules of the new proposal.

去中心化自治组织（DAO）类似于链上政府，参与者可以使用一些治理代币对提案进行投票。可以实施各种共识机制来确定提案是否会通过，如果通过，那么 DAO 将开始根据新提案的规则运行。

In this implementation, the user deposits governance tokens and receives some number of votes that can be cast and recast on different proposals. They can vote in favor or against proposals and they can transform their votes back into the governance tokens if they wish to withdraw.

在此实施中，用户存入治理代币并获得一定数量的选票，这些选票可以针对不同的提案进行投票和重新投票。他们可以投票赞成或反对提案，如果他们希望撤回，他们可以将投票转换回治理代币。

The smart contract is mostly complete for the basic implementation. There are some issues that need to be worked out but a UI can be started.

智能合约的实施基本完成。有一些问题需要解决，但已经可以启动 UI。
The user interface does not currently exist.
用户界面当前还不存在。
