乐观：第 2 层网络使以太坊交易更快、更便宜

Optimism 是一个与以太坊合作的第 2 层网络，可以使交易更快、更便宜。它使用“乐观汇总”方法，其中交易在链下处理，然后批量发布到链上。

Optimism is a Layer 2 network designed to enhance the speed, efficiency, and affordability of transactions on the Ethereum blockchain. It employs an innovative technique known as an “optimistic rollup.”

Optimism 是一个第 2 层网络，旨在提高以太坊区块链上交易的速度、效率和可承受性。它采用了一种称为“乐观汇总”的创新技术。

In this approach, transactions are processed off-chain, significantly reducing the load on Ethereum's main network. Subsequently, these transactions are periodically bundled together and posted on-chain, minimizing gas fees and expediting transaction times.

在这种方法中，交易在链下处理，显着减少了以太坊主网络的负载。随后，这些交易会定期捆绑在一起并发布在链上，从而最大限度地减少天然气费用并加快交易时间。

The native token of the Optimism network is $OP, which serves two primary functions. It empowers holders with governance rights over the network, enabling them to participate in crucial decision-making processes. Additionally, $OP can be traded on exchanges such as Coinbase, facilitating convenient entry and exit from the Optimism ecosystem.

Optimism 网络的原生代币是 $OP，它有两个主要功能。它赋予持有者网络治理权，使他们能够参与关键决策过程。此外，$OP可以在Coinbase等交易所进行交易，方便进出Optimism生态系统。

Compared to transactions on Ethereum's mainnet, Optimism offers substantial cost savings, typically reducing fees by a factor of ten. This is achieved through a combination of lower transaction fees and faster processing times, making Optimism an attractive option for users seeking to optimize their transaction costs.

与以太坊主网上的交易相比，Optimism 可以节省大量成本，通常可以将费用降低十倍。这是通过较低的交易费用和更快的处理时间相结合来实现的，这使得 Optimism 对于寻求优化交易成本的用户来说成为一个有吸引力的选择。

Optimism generates revenue through two primary channels: sequencer fees and blockspace demand. The revenue collected from sequencers is allocated towards funding public goods within the Optimism ecosystem, such as developer tools and infrastructure.

乐观通过两个主要渠道产生收入：排序器费用和区块空间需求。从测序仪收集的收入被分配用于资助 Optimism 生态系统内的公共产品，例如开发人员工具和基础设施。

Moreover, the network encompasses multiple chains, including Base, Fraxtal, and Mode, which are collectively integrated into the “Superchain” ecosystem.

此外，该网络包含多个链，包括Base、Fraxtal和Mode，这些链共同集成到“超级链”生态系统中。

To interact with the Optimism network, users can leverage popular wallets such as Coinbase Wallet and MetaMask. These wallets provide seamless integration with Optimism, enabling users to effortlessly conduct transactions and access DeFi platforms.

为了与 Optimism 网络进行交互，用户可以利用 Coinbase Wallet 和 MetaMask 等流行的钱包。这些钱包与 Optimism 无缝集成，使用户能够轻松进行交易并访问 DeFi 平台。

Additionally, the Optimism Bridge serves as a convenient gateway for transferring assets from Ethereum to Optimism. Through this bridge, users can efficiently move their funds to access a wide range of DeFi protocols, including Uniswap and Synthetix.

此外，Optimism Bridge 还可以作为将资产从以太坊转移到 Optimism 的便捷网关。通过这座桥梁，用户可以有效地将资金转移到各种 DeFi 协议，包括 Uniswap 和 Synthetix。

When transferring assets between Ethereum and Optimism, it is crucial to exercise caution to prevent potential losses. Users are advised to thoroughly verify the transaction details and utilize the official bridge for optimal safety.

在以太坊和 Optimism 之间转移资产时，务必谨慎行事，防止潜在损失。建议用户彻底验证交易详细信息并使用官方桥以获得最佳安全性。

For a broader selection of tokens, third-party bridges may be employed to facilitate withdrawals from the Optimism network. Among these tokens are cDAI, wstETH, and FEI.

为了获得更广泛的代币选择，可以使用第三方桥来促进从 Optimism 网络的提款。这些代币包括 cDAI、wstETH 和 FEI。

On exchanges like Binance and DigiFinex, the $OP token has experienced high trading volumes, reaching a market capitalization of $2.2 billion. Within the broader cryptocurrency landscape, Optimism faces competition from other Layer 2 solutions.

在币安和 DigiFinex 等交易所，$OP 代币的交易量很高，市值达到 22 亿美元。在更广泛的加密货币领域，Optimism 面临着来自其他 Layer 2 解决方案的竞争。

Arbitrum, Polygon, and zkSync are among the notable contenders, each offering unique strengths and approaches to scaling Ethereum. Ultimately, the choice of Layer 2 network depends on the specific requirements and preferences of users.

Arbitrum、Polygon 和 zkSync 都是著名的竞争者，它们各自提供了独特的优势和扩展以太坊的方法。最终，二层网络的选择取决于用户的具体要求和偏好。
