What Is Arbitrum and How Does It Work?

什么是仲裁以及它如何运作？

Arbitrum is an L2 (Layer-2) scaling solution that is built on top of Ethereum. It focuses on fast smart contract transactions and lower gas fees. Essentially, the Arbitrum blockchain delegates various complex tasks from the base Layer 1 to the second chain to make the base a little lighter. But why was it needed?

Arbitrum 是一种构建在以太坊之上的 L2（第 2 层）扩展解决方案。它专注于快速的智能合约交易和较低的汽油费。本质上，Arbitrum 区块链将各种复杂的任务从基础层 1 委托给第二层链，以使基础变得更轻一些。但为什么需要它呢？

Well, Ethereum is one of the most popular networks in the market, if not even the most popular. However, this popularity also comes with concerning network congestion. And with network congestion, there come the astronomical transaction costs.

好吧，以太坊即使不是最受欢迎的网络，也是市场上最受欢迎的网络之一。然而，这种流行也伴随着网络拥塞的问题。随着网络拥塞，交易成本也随之而来。

Now, Arbitrum (along with other scaling solutions) comes to make Ethereum’s work easier by taking on some of its tasks. Basically, Arbitrum aims to reduce the data storage on Ethereum by taking transactions and processing them off-chain before settling them on-chain through the use of blockchain rollups.

现在，Arbitrum（以及其他扩展解决方案）通过承担以太坊的一些任务来使以太坊的工作变得更容易。基本上，Arbitrum 的目标是通过使用区块链汇总将交易进行链下处理并在链上进行结算，从而减少以太坊上的数据存储。

This way, Ethereum no longer needs to validate separate transactions, as it can confirm a “rolled up” group of transactions. And this helps Ethereum to process transactions faster.

这样，以太坊不再需要验证单独的交易，因为它可以确认“汇总”的一组交易。这有助于以太坊更快地处理交易。

To achieve this, Arbitrum uses a particular type of rollups, called optimistic rollups. Simply (and shortly) put, optimistic rollups rely on an “optimistic assumption” that most transactions are valid. Thus, it compresses them to reduce gas fees and optimize the block space.

为了实现这一目标，Arbitrum 使用一种特殊类型的汇总，称为乐观汇总。简而言之，乐观汇总依赖于大多数交易都是有效的“乐观假设”。因此，它压缩它们以减少天然气费用并优化区块空间。

Why Add Arbitrum Network to MetaMask?

为什么将 Arbitrum 网络添加到 MetaMask？

Both MetaMask and Arbitrum come with their significant advantages, and just imagine what these advantages can do when they are combined. Simply put, they do wonders, and many users decide to add Arbitrum to MetaMask in order to benefit from all these features and perks.

MetaMask 和 Arbitrum 都有其显着的优势，想象一下这些优势结合起来会产生什么效果。简而言之，他们创造了奇迹，许多用户决定将 Arbitrum 添加到 MetaMask 中，以便从所有这些功能和福利中受益。

Integrating Arbitrum with MetaMask can offer new possibilities for those using MetaMask, allowing them to interact with the Ethereum network more efficiently and cost-effectively. Basically, when you use Arbitrum, you actually use Ethereum through Arbitrum, thus you benefit from Ethereum’s ecosystem while also achieving lower gas fees and higher scalability.

将 Arbitrum 与 MetaMask 集成可以为使用 MetaMask 的用户提供新的可能性，使他们能够更高效、更经济地与以太坊网络进行交互。基本上，当您使用 Arbitrum 时，您实际上是通过 Arbitrum 使用以太坊，因此您可以从以太坊的生态系统中受益，同时还可以获得更低的 Gas 费用和更高的可扩展性。
