🌴 Sway 日 (SwayDay)
We hosted the second episode of Sway Day, a monthly discussion about all-things Sway. This time, the main topic was Predicates - Why and how you should use them. where we had the chance to have the founders of one of our granted projects, Poolshark, a DEX with a Price-Time-Priority feature, building on Fuel.
我们主持了 Sway日 的第二集，这是一个关于所有 Sway 的月度讨论。这一次的主题是**谓词 - 为什么以及如何使用它们**。在那里，我们有机会拥有我们的一个授权项目 Poolshark 的创始人，这是一个基于 Fuel 的，具有价格-时间优先功能的去中心化交易所。

💻 技术更新 (Technical Updates)
Fuelup
Fuelup是什么 (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.
-
Introduction of testnet-specific toolchains:
beta-1andbeta-2toolchains. Installable throughfuelup toolchain install beta-2for example; -
forc-docandfuel-indexerare now packaged in a default toolchain; -
fueluphas completions thanks to an external contributor @0xYYY; -
fuelup updatecan be used as a shorthand forfuelup toolchain install latest|nightly; -
引入特定测试网的工具链：
beta-1和beta-2工具链。例如，可通过fuelup toolchain install beta-2安装； -
forc-doc和fuel-indexer现在打包在默认工具链中； -
感谢外部贡献者 @0xYYY，
fuelup已经完成； -
fuelup update可以用作fuelup toolchain install latest|nightly的简写；
Sway库 (Sway Libraries)
The Sway Libraries Repository
The purpose of this repository is to contain libraries which users can import and use that are not part of the standard library.
此存储库的目的是包含用户可以导入和使用的不属于标准库的库。
These libraries contain helper functions, generalized standards, and other tools valuable to blockchain development.
这些库包含辅助函数、通用标准和其他对区块链开发有价值的工具。
⚠️ Note: Sway is a language under heavy development therefore the libraries may not be the most ergonomic. Over time they should receive updates/improvements in order to demonstrate how Sway can be used in real use cases.
⚠️ 注意：Sway 是一种正在大力开发的语言，因此库可能不是最符合人体工程学的。随着时间的推移，他们应该会收到更新/改进，以演示如何在实际用例中使用 Sway。
So far, the following libraries are available to use:
到目前为止，可以使用以下库：
- Binary Merkle Proof is used to verify Binary Merkle Trees computed off-chain.
Binary Merkle Proof 用于验证链下计算的二进制默克尔树。 - Non-Fungible Token (NFT) is a token library which provides unqiue collectibles, identified and differentiated by token IDs.
Non-Fungible Token (NFT) 是一个提供独特收藏品的代币库，通过代币 ID 识别和区分. - String is an interface to implement dynamic length strings that are UTF-8 encoded.
String 是实现 UTF-8 编码的动态长度字符串的接口。 - Signed Integers is an interface to implement signed integers.
Signed Integers 是一个实现有符号整数的接口。 - Unsigned Fixed Point 64 bit is an interface to implement fixed-point 64 bit numbers.
Unsigned Fixed Point 64 bit 是实现定点 64 位数字的接口。
Sway Applications
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 应用存储库的目的是演示可以使用 Sway 构建的内容并促进良好的开发实践。
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!
所以，存储库应该被视为一个活跃的项目，因为应用将得到积极维护，因此它们很可能永远不会达到最终形式！
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.
这个存储库还很年轻，所以还没有任何人可以使用，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的工作。
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，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。
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
注意This does not mean that they are complete nor that development has ceased.
这并不意味着它们已经完成，也不意味着开发已经停止。
-
New English Auction application. The auction allows sellers to put up assets that they would like to sell based on an initial price and a reserve price. Users bid until the reserve price is met or the time expires;
新的英语拍卖应用。拍卖允许卖家根据初始价格和底价出售他们想要出售的资产。用户竞价直至达到底价或直到时间结束； -
New Name Registry application which allows users to own a human-readable name that can be used to transfer assets. This means that a user does not have to use the
hexformat of random characters; instead, they can use a memorable word/name to transfer;
新的名称注册应用允许用户拥有可用于转移资产的人类可读名称。这意味着用户不必使用随机字符的hex格式；相反，他们可以使用一个好记的词/名字来转移； -
New Over-The-Counter (OTC) Swap Predicate application demonstrates a proof-of-concept whereby coins to be swapped are locked behind predicates. Anyone can spend these coins, as long as their transaction sends a certain quantity of coins back to a provided address - thereby completing a stateless atomic swap between two parties.
新的场外交易 (OTC) Swap Predicate 应用演示了一个概念验证，其中要交换的代币被锁定在谓词后面。任何人都可以花费这些代币，只要他们的交易将一定数量的硬币发送回提供的地址——从而完成两方之间的无状态原子交换。
Note: This minimal example could serve as the basis for an entire order book exchange, where orders are circulated off-chain, and settled solely through the funding and spending of predicates. This design would be orders of magnitude more performant than a storage-backed smart contract implementation.
注意： 这个最小的例子可以作为整个订单簿交换的基础，其中订单在链下流通，并仅通过谓词的资金和支出来结算。这种设计的性能将比存储支持的智能合约实现高出几个数量级。
- New Automated Market Maker (AMM) application. It allows users to swap assets via liquidity pools;
新的自动做市商 (AMM) 应用。它允许用户通过流动性池交换资产；
