嘿，猴友们！你们知道吗？在以太坊的世界里，有一群叫做L2的家伙们，他们专门解决以太坊的“吞吐量”问题。

今天，咱们就来揭开他们的神秘面纱，看看他们是如何让以太坊更快、更便宜的！ 

Hey there, fellow monkeys! Did you know that in the world of Ethereum, there's a group of guys called L2 who specialize in solving Ethereum's "throughput" problem?

Today, let's unveil their mysterious veil and see how they make Ethereum faster and cheaper!

第一层：塔基 Layer 1: The Foundation

以太坊网络就像一座高大的塔，所有交易都发生在这里。可是，这座塔有点拥挤，交易费用也有点贵。

于是，就有了L2这帮家伙，他们想办法帮塔解决扩容问题。

The Ethereum network is like a tall tower where all transactions take place. However, this tower is a bit crowded, and transaction fees can be expensive. 

That's where the L2 folks come in to help the tower with its scalability issues.

第二层：桥梁 Layer 2: The Bridges

L2扩容方案就像一座连接塔基和上层的桥梁，它们帮助提高以太坊的交易速度和处理能力。来看看这几位“桥梁大师”： 

L2 scaling solutions are like bridges connecting the foundation to the upper layers, helping to enhance Ethereum's transaction speed and processing capacity. Let's meet these "bridge masters":

Arbitrum：这家伙是个速度狂魔！他优化了交易处理机制，让交易速度飞快。就像你去买热门演唱会的门票，用了Arbitrum的L2网络，瞬间秒杀其他人，避免了长时间排队和高昂的手续费。

Arbitrum: This guy is a speed demon! He optimizes transaction processing mechanisms, making transactions lightning-fast. Imagine buying tickets for a popular concert, using Arbitrum's L2 network, you'd instantly outperform others, avoiding long queues and hefty fees.

Arbitrum科普

Arbitrum是一种Layer 2扩展解决方案，它使用Optimistic的Rollups来增加吞吐量并降低燃气费用。

它通过将多个交易捆绑成一个批次，然后将它们提交到以太坊主网来实现这一点。

Arbitrum与以太坊智能合约兼容，这意味着它可以与现有的dApp和DeFi协议一起使用。

Arbitrum is a Layer 2 scaling solution that uses optimistic rollups to increase throughput and reduce gas fees. 

It achieves this by bundling multiple transactions into a single batch and then submitting them to the Ethereum mainnet. 

Arbitrum is compatible with Ethereum smart contracts, which means it can be used with existing dApps and DeFi protocols.

Optimism：这家伙有点“乐观”，总是看到好的一面！他利用乐观交易确认机制，实现了高吞吐量和低延迟。

想象你在游乐园等待刺激的过山车，用了Optimism，秒进过山车，嗨起来！

Optimism: This guy is a bit "optimistic" and always sees the bright side! He leverages optimistic rollup technology to achieve high throughput and low latency. 

Picture yourself waiting for an exciting roller coaster at an amusement park. With Optimism, you'd jump onto the roller coaster in no time and have a blast!

Optimism科普

Optimism是另一种使用optimistic Rollups技术来增加吞吐量和降低燃气费用的Layer 2扩展解决方案。

它旨在与以太坊智能合约兼容，并支持以太坊虚拟机（EVM）。

Optimism还提供了一种名为“欺诈证明”的功能，允许用户挑战无效交易。

Optimism is another Layer 2 scaling solution that uses optimistic rollups to increase throughput and reduce gas fees.

It is designed to be compatible with Ethereum smart contracts and supports the Ethereum Virtual Machine (EVM). 

Optimism also offers a feature called "fraud proofs," which allows users to challenge invalid transactions.

Optimistic Rollup 是第一个看到大量用户从 L1 桥接资金的通用总结。

这是人们第一次真正有机会获得以太坊的安全保证，而无需支付高昂的gas费。

Optimistic Rollup is the first generalization that sees a large number of users bridging funds from L1. 

This is the first time people have a real opportunity to obtain Ethereum's security guarantees without paying high gas fees.

zkSync：这家伙是个“魔术师”！他用零知识证明技术将大量交易压缩成一个证明，在以太坊主链上提交。

就像魔术师变戏法，将一串彩色的绳子瞬间变成一根绳子，交易也变得快又高效。

zkSync: This guy is a "magician"! He uses zero-knowledge proofs to compress a large number of transactions into a single proof submitted to the Ethereum main chain. 

It's like a magician turning a colorful rope into a single rope in an instant. Transactions become fast and efficient with zkSync's magic.

zkSync是一种Layer 2的扩容方案，它使用零知识证明来增加吞吐量并降低燃气费用。它被设计为与以太坊智能合约兼容，并支持以太坊虚拟机（EVM）。

zkSync还提供了一个名为“zkPorter”的功能，允许用户聚合交易并进一步降低燃气成本。

zkSync is a Layer 2 scaling solution that uses zero-knowledge proofs to increase throughput and reduce gas fees. It is designed to be compatible with Ethereum smart contracts and supports the Ethereum Virtual Machine (EVM). 

zkSync also offers a feature called "zkPorter," which allows users to aggregate transactions and reduce gas costs even further.

zkSync 宣布已成功完成里程碑：合并证明。

通过集成有效性证明，zkSync 2.0 正式成为世界上第一个在公共测试网上运行的 zkEVM。

zkSync has announced the successful completion of Milestone：Merger Proof.

By integrating Validity Proof, zkSync 2.0 has officially become the world's first zkEVM running on a public testnet.

zkEVM 是第一个与以太坊完全兼容的零知识扩展解决方案。它使开发人员可以非常轻松地从与 EVM 兼容的链中迁移他们的 dApp。

开发人员可以简单地部署他们现有的智能合约，而无需进行任何额外的更改。

zkEVM is the first zero-knowledge scaling solution that is fully compatible with Ethereum. It allows developers to seamlessly migrate their dApps from EVM-compatible chains with great ease. 

Developers can simply deploy their existing smart contracts without the need for any additional modifications.

Starknet：这家伙是个建筑师，他擅长打造高楼大厦！他让开发者在L2上构建定制化的应用程序，提供更高的吞吐量和更低的费用。

就像建筑师设计一座摩天大楼，Starknet让开发者畅想无限创意。

Starknet: This guy is an architect, skilled at constructing tall buildings! He enables developers to build customized applications on L2, offering higher throughput and lower costs. 

Just like an architect designing a skyscraper, Starknet allows developers to unleash their creativity.

StarkNet 是一个 Layer 2 扩展方案，使用 zk-rollups 来增加吞吐量并降低 gas 费用。它被设计为与以太坊智能合约兼容，并支持以太坊虚拟机 (EVM)。

StarkNet 还提供了一个名为 "validium" 的功能，允许用户在链外执行更复杂的计算。

StarkNet is a Layer 2 scaling solution that uses zk-rollups to increase throughput and reduce gas fees. It is designed to be compatible with Ethereum smart contracts and supports the Ethereum Virtual Machine (EVM). 

StarkNet also offers a feature called "validium," which allows users to execute more complex computations off-chain.

Polygon：这家伙是个“地铁管家”，专门负责连接各个塔楼的快捷交通。Polygon通过侧链和桥接技术，提供快速、便宜的交易体验。

就像坐着地铁畅游城市，你可以轻松穿梭于不同的L2网络，享受便宜又快速的交易。

Polygon: This guy is a "subway caretaker," specializing in connecting different tower buildings with a fast transportation system. 

Polygon provides fast and cost-effective transactions through sidechains and bridging technology.

It's like riding the subway, effortlessly traveling between different L2 networks and enjoying cheap and fast transactions.

多边形（原名Matic Network）是一种使用Plasma的第二层扩展解决方案，可增加吞吐量并降低燃气费用。

它旨在与以太坊智能合约兼容，并支持以太坊虚拟机（EVM）。

多边形还与其他区块链相互操作，这意味着它可以用于在不同网络之间传输资产。

Polygon (formerly Matic Network) is a Layer 2 scaling solution that uses Plasma to increase throughput and reduce gas fees. 

It is designed to be compatible with Ethereum smart contracts and supports the Ethereum Virtual Machine (EVM). 

Polygon is also interoperable with other blockchains, which means it can be used to transfer assets across different networks.

总结 Conclusion

通过这帮L2家伙的努力，以太坊的世界变得更加迅捷、更加经济实惠。

他们为用户提供了更快、更便宜的交易，为开发者创造了更多的空间。

Thanks to the efforts of these L2 guys, the Ethereum world has become faster and more affordable.
