樂觀：第 2 層網路讓以太坊交易更快、更便宜

Optimism 是一個與以太坊合作的第 2 層網絡，可以讓交易更快、更便宜。它使用“樂觀匯總”方法，其中交易在鏈下處理，然後批量發佈到鏈上。

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 是一個第 2 層網絡，旨在提高以太坊區塊鏈上交易的速度、效率和可承受性。它採用了一種稱為「樂觀匯總」的創新技術。

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.

在這種方法中，交易在鏈下處理，顯著減少了以太坊主網路的負載。隨後，這些交易會定期捆綁在一起並發佈在鏈上，從而最大限度地減少天然氣費用並加快交易時間。

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 網路的原生代幣是 $OP，它有兩個主要功能。它賦予持有者網路治理權，使他們能夠參與關鍵決策過程。此外，$OP可在Coinbase等交易所進行交易，方便進出Optimism生態系。

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.

與以太坊主網上的交易相比，Optimism 可以節省大量成本，通常可以將費用降低十倍。這是透過較低的交易費用和更快的處理時間相結合來實現的，這使得 Optimism 對於尋求優化交易成本的用戶來說成為一個有吸引力的選擇。

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.

樂觀透過兩個主要管道產生收入：排序器費用和區塊空間需求。從定序儀收集的收入被分配用於資助 Optimism 生態系統內的公共產品，例如開發人員工具和基礎設施。

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

此外，此網路包含多個鏈，包括Base、Fraxtal和Mode，這些鏈共同整合到「超級鏈」生態系統中。

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.

為了與 Optimism 網路進行交互，用戶可以利用 Coinbase Wallet 和 MetaMask 等流行的錢包。這些錢包與 Optimism 無縫集成，使用戶能夠輕鬆進行交易並訪問 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 還可以作為將資產從以太坊轉移到 Optimism 的便利網關。透過這座橋樑，用戶可以有效地將資金轉移到各種 DeFi 協議，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 之間轉移資產時，請務必謹慎行事，以防止潛在損失。建議用戶徹底驗證交易詳細資訊並使用官方橋以獲得最佳安全性。

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.

為了獲得更廣泛的代幣選擇，可以使用第三方橋來促進從 Optimism 網路的提款。這些代幣包括 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.

在幣安和 DigiFinex 等交易所，$OP 代幣的交易量很高，市值達到 22 億美元。在更廣泛的加密貨幣領域，Optimism 面臨著來自其他 Layer 2 解決方案的競爭。

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 都是著名的競爭者，它們各自提供了獨特的優勢和擴展以太坊的方法。最終，二層網路的選擇取決於用戶的特定要求和偏好。
