SIDECHAINS的兴起：区块链技术的有前途的领域

目前最重要的创新之一是Sidechains的兴起，这是一个有前途的区块链技术领域

The world of cryptocurrencies moves fast. New coins, chains, and technologies emerge constantly, so it is easy to feel overwhelmed these days. Yet, one of the most important innovations to follow right now is the rise of sidechains, a promising area of blockchain technology set to revolutionize blockchain scalability and interoperability.

加密货币的世界很快。新的硬币，链条和技术不断出现，因此这些天很容易感到不知所措。然而，目前要遵循的最重要的创新之一是Sidechains的兴起，Sidechains的崛起是一个有前途的区块链技术领域，旨在彻底改变区块链的可伸缩性和互操作性。

Sidechains are central in the decade-long fight to scale blockchains and improve interoperability between them. In this article, we will break down what sidechains are, how they work, how you can use them effectively, and dive into a few of the most popular sidechains available today.

在长达十年的斗争中，Sidechains是缩放区块链并改善它们之间的互操作性的核心。在本文中，我们将分解什么是侧链，它们的工作方式，如何有效地使用它们，并潜入当今最受欢迎的侧技术。

What Is a Sidechain?

什么是Sidechain？

The largest and most popular crypto networks, namely Bitcoin and Ethereum, often face issues like high fees and slow transaction times, largely because they sacrifice scalability for decentralization and security. Other networks, such as Solana or Binance Smart Chain (BSC), use much more centralized consensus mechanisms to speed up transactions and keep fees down.

最大，最受欢迎的加密网络，即比特币和以太坊，通常面临高费用和缓慢交易时间之类的问题，这主要是因为它们牺牲了用于分散和安全性的可扩展性。其他网络（例如Solana或Binance Smart Chain（BSC））使用更集中的共识机制来加快交易并保持费用。

A sidechain is a separate blockchain that runs in parallel to the main one (often referred to as the mainchain). The sidechain is connected to the main blockchain through a two-way bridge, which allows assets to move easily between the two.

Sidechain是一个单独的区块链，与主链平行运行（通常称为Mainchain）。 Sidechain通过双向桥连接到主区块链，这使资产可以在两者之间轻松移动。

Even though it might sound like it, sidechains aren’t just clones of their mainchains. Sidechains operate independently and have their own consensus mechanisms, rules, and validators. This independent operation is what makes them so powerful. They allow developers to experiment, scale, and even add features without messing with the core blockchain.

即使听起来像是这样，Sidechains不仅是其主链的克隆。 Sidechains独立运作，并拥有自己的共识机制，规则和验证者。这种独立的操作使它们如此强大。它们允许开发人员实验，扩展甚至添加功能而不会与核心区块链混乱。

Why Do Sidechains Exist?

为什么存在Sidechains？

Sidechains were created to solve the limitations of major blockchains like Bitcoin and Ethereum. The networks can be expensive and slow when busy, and sidechains offer the perfect solution to this problem. They offer ways to run smart contracts, scale transactions, and/or support custom applications with low fees and fast transactions, all without clogging up the mainchain.

创建了Sidechains来解决比特币和以太坊等主要区块链的局限性。忙碌时，网络可能会昂贵且缓慢，而Sidechains为这个问题提供了完美的解决方案。他们提供运行智能合约，规模交易和/或支持具有低费用和快速交易的自定义应用程序的方法，而无需堵塞主链。

You can think of them as specialized highways that connect to the main freeway. They help relieve traffic and allow for faster travel, and they can be tailored to different kinds of vehicles. However, instead of cars and trucks, sidechains host dApps, games, DeFi tools, and more.

您可以将它们视为连接到主高速公路的专门高速公路。它们有助于缓解交通并允许更快的旅行，并且可以针对不同类型的车辆量身定制。但是，Sidechains主持DAPP，游戏，Defi工具等，而不是汽车和卡车，而是使用汽车和卡车。

How Sidechains Work

Sidechains的工作方式

At a high level, sidechains function by connecting to the main blockchain using a two-way bridge. The two-way bridge works like any other crypto bridge, allowing users to lock up assets on the mainchain and then unlock the corresponding amount on the sidechain. Later, they can also reverse the process and move the funds back.

在高水平上，Sidechains通过使用双向桥连接到主区块链来发挥作用。双向桥梁的工作原理就像其他任何加密桥梁一样，使用户可以将资产锁定在主链上，然后在Sidechain上解锁相应的金额。后来，他们还可以扭转过程并将资金移回。

Let’s say that you decided to move ETH from Ethereum to a sidechain like Polygon PoS. Here’s what you would need to do.

假设您决定将ETH从以太坊转移到像Polygon Pos这样的Sidechain。这是您需要做的。

You would navigate to Polygon’s official bridge and deposit your ETH into its smart contract. The same amount would then appear on Polygon as wrapped ETH. Note that transaction fees on Polygon are paid with Polygon (MATIC), so make sure to transfer at least a few MATIC tokens as well. Once the transaction finishes, you can now use the wrapped ETH in apps running on Polygon, which is often much faster and cheaper. Once you are done, you can simply move your

您将导航到Polygon的官方桥梁，并将您的ETH存入其智能合同中。然后，在多边形上，同样的数量将与包裹的eth出现。请注意，多边形（Matic）支付多边形的交易费用，因此请确保至少也会传输一些Matic令牌。交易完成后，您现在可以在Polygon上运行的应用程序中使用包裹的ETH，该应用程序通常更快，更便宜。完成后，您可以简单地移动您的
