Layer 2：區塊鏈革命的催化劑

Layer 2 networks are now an integral part of the Ethereum and Bitcoin ecosystems, providing unparalleled scalability and cost-effectiveness. Their transformative impact has revolutionized blockchain usage, offering users a seamless and efficient experience.

第 2 層網路現已成為以太坊和比特幣生態系統不可或缺的一部分，提供無與倫比的可擴展性和成本效益。它們的變革性影響徹底改變了區塊鏈的使用，為用戶提供無縫、高效的體驗。

The Evolution of Layer 2s: From Idea to Reality

Layer 2 的演變：從想法到現實

The concept of Layer 2s has evolved significantly over the past decade. Initially conceived as a theoretical solution to blockchain scalability challenges, they have now materialized into fully functional networks that have transformed the on-chain landscape. Layer 2s have emerged as the driving force behind the explosive growth of blockchain applications, empowering users with faster, cheaper, and more versatile transactions.

Layer 2 的概念在過去十年中發生了顯著的變化。它們最初被認為是解決區塊鏈可擴展性挑戰的理論解決方案，現在已具體化為功能齊全的網絡，改變了鏈上格局。 Layer 2 已成為區塊鏈應用爆炸性成長背後的驅動力，使用戶能夠進行更快、更便宜、更通用的交易。

The Role of Layer 2s: Enhancing Scalability and Security

第 2 層的作用：增強可擴展性和安全性

Layer 2 networks operate by leveraging the security of their parent chain, such as Ethereum or Bitcoin, while executing transactions on a separate, purpose-built blockchain. This unique architecture enables Layer 2s to process vast volumes of transactions at significantly reduced costs compared to Layer 1 blockchains. Moreover, the security of the parent chain ensures that Layer 2 transactions remain immutable and tamper-proof.

第 2 層網路透過利用其父鏈（例如以太坊或比特幣）的安全性來運行，同時在單獨的專用區塊鏈上執行交易。與第 1 層區塊鏈相比，這種獨特的架構使第 2 層能夠以顯著降低的成本處理大量交易。此外，母鏈的安全性保證了第2層交易保持不可變和防篡改。

The Success of Ethereum Layer 2s: A Resounding Victory

以太坊 Layer 2 的成功：一場響亮的勝利

Ethereum-based Layer 2 solutions, such as Polygon, Optimism, Arbitrum, and Base, have witnessed tremendous adoption and now dominate the EVM ecosystem. These networks have significantly surpassed Ethereum in terms of economic activity, both in transaction volume and monetary value. They have effectively addressed the scalability limitations of Ethereum, allowing users to enjoy low fees and near-instant transaction speeds.

基於以太坊的 Layer 2 解決方案，例如 Polygon、Optimism、Arbitrum 和 Base，已經得到了廣泛的採用，現在主導了 EVM 生態系統。這些網路在經濟活動方面（無論是交易量還是貨幣價值）都顯著超過了以太坊。他們有效地解決了以太坊的可擴展性限制，讓用戶享受低費用和近乎即時的交易速度。

The Rise of Bitcoin Layer 2s: Unleashing New Potential

比特幣 Layer 2 的崛起：釋放新潛力

Bitcoin, the pioneer of blockchain technology, has also embraced the transformative power of Layer 2s. Inspired by the success of Ethereum Layer 2s, a plethora of Bitcoin Layer 2 networks have emerged, offering similar benefits such as enhanced scalability and reduced fees. These Layer 2s are paving the way for Bitcoin to accommodate new use cases, including DeFi, NFTs, and sophisticated smart contracts.

比特幣作為區塊鏈技術的先驅，也擁抱了 Layer 2 的變革力量。受以太坊 Layer 2 成功的啟發，出現了大量的比特幣 Layer 2 網絡，提供了類似的好處，例如增強的可擴展性和降低的費用。這些 Layer 2 為比特幣適應新的用例鋪平了道路，包括 DeFi、NFT 和複雜的智慧合約。
