Layer 3：區塊鏈擴容革命的下一個前沿

在以太坊 Dencun 升級之後，第 3 層 (L3) 解決方案已成為區塊鏈擴展的潛在下一步。 L3 提供針對特定社群和用例（例如企業區塊鏈應用程式或遊戲）量身定制的專業生態系統。然而，他們克服天然氣費用並為整體擴展工作做出貢獻的能力仍然存在疑問。透過研究 L3 功能、部署範例和開發框架，本文探討了 L3 在不斷發展的以太坊生態系統中的潛在價值和限制。

Layer 3s: The Next Frontier in Blockchain Scaling

Layer 3：區塊鏈擴展的下一個前沿

In the wake of Ethereum's Dencun upgrade, which significantly reduced fees on most Layer 2 (L2) networks, the blockchain community is eagerly looking ahead to the next step in scaling. Layer 3 (L3) solutions have emerged as a promising contender, offering specialized environments tailored to specific communities and use cases.

以太坊的 Dencun 升級顯著降低了大多數第 2 層 (L2) 網路的費用，區塊鏈社群熱切期待下一步的擴展。第 3 層 (L3) 解決方案已成為一個有前途的競爭者，提供針對特定社群和用例量身定制的專業環境。

Expanding the Blockchain Market

擴大區塊鏈市場

L3s allow for the creation of highly customized ecosystems that cater to specific needs, broadening the reach of the blockchain market. As L2s have established themselves as hubs for various use cases (e.g., gaming, DeFi), L3s will likely follow suit by providing specialized environments that enhance the functionality of their L2 hosts.

L3 允許創建滿足特定需求的高度客製化的生態系統，從而擴大區塊鏈市場的範圍。隨著 L2 已經成為各種用例（例如遊戲、DeFi）的中心，L3 可能會效仿，提供專門的環境來增強 L2 主機的功能。

Enhanced Customization and Functionality

增強的客製化和功能

L3s offer unparalleled customizability, enabling developers to augment their applications and scale them effectively through methods such as:

L3 提供無與倫比的可自訂性，使開發人員能夠透過以下方法增強其應用程式並有效擴展它們：

• Reduced Settlement Costs: L3s significantly reduce settlement costs, making development more economically viable.
• Arenas for Experimentation: The customizable nature of L3s fosters experimentation with new business models, virtual machines (VMs), data availability solutions, and governance models, which are often not feasible on L1 or L2 networks.
• Privacy Enhancements: L3s can be configured to provide enhanced privacy, enabling anonymous transactions or encrypted messaging services, opening up new possibilities for enterprise businesses requiring this level of confidentiality.
• New Economic Models: L3s can develop innovative economic models where tokens other than ETH can be burned for gas, potentially increasing the value of those tokens over time.

Examples of L3s in Action

降低結算成本： L3 顯著降低結算成本，使開發在經濟上更加可行。實驗場所：L3 的可自訂性質促進了新業務模型、虛擬機器(VM)、資料可用性解決方案和治理模型的實驗，而這些通常是不可行的。在L1 或L2 網路上可行。隱私增強：L3 可以配置為提供增強的隱私，實現匿名交易或加密訊息服務，為需要這種保密級別的企業業務開闢新的可能性。新經濟模型：L3 可以開發創新的經濟模型除了 ETH 之外，其他代幣都可以燃燒以獲取 Gas，隨著時間的推移，這些代幣的價值可能會增加。L3 的實際應用範例

Several L3 projects have already emerged, demonstrating the practical benefits of this scaling approach:

多個 L3 項目已經出現，展示了這種擴展方法的實際好處：

• Yuga's ApeChain and Azuki's AnimeChain: These L3s, deployed on Arbitrum's Orbit framework, provide tailored environments for the respective BAYC and Azuki NFT communities, offering new use cases for their tokens.
• DegenChain and Frame Chain: DegenChain offers a cost-effective L3 solution for scaling the DEGEN ecosystem, while Frame Chain provides high throughput and minimal gas costs for mini-apps deployed on Farcaster.
• Xai Network: Specifically designed for Web3 gaming, Xai Network simplifies wallet management for gamers and offers enhanced gas and contract capacities, making it an ideal platform for popular games like Crypto Unicorns.

Frameworks for Building L3s

Yuga 的ApeChain 和Azuki 的AnimeChain：這些L3 部署在 Arbitrum 的Orbit 框架上，為各自的BAYC 和Azuki NFT 社區提供量身定制的環境，為其代幣提供新的用例。DegenChain 和Frame Chain：DegenChain 提供了一種經濟高效的L3 擴展解決方案 DEGEN 生態系統，而Frame Chain 為Farcaster 上部署的迷你應用程式提供高吞吐量和最低的Gas 成本。Xai Network：Xai Network 專為Web3 遊戲而設計，簡化了遊戲玩家的錢包管理，並提供增強的Gas 和合約容量，使其成為理想的選擇適用於 Crypto Unicorns 等流行遊戲的平台。構建 L3 的框架

The development of L3s has been facilitated by the emergence of standardized frameworks that simplify the process of deployment. Three leading solutions include:

簡化部署過程的標準化框架的出現促進了 L3 的發展。三個領先的解決方案包括：

• Arbitrum Orbits: Allows anyone to create highly customized Layer 3 blockchains, offering unparalleled scalability and ease of deployment.
• OP Stack: Provides a toolkit for building faster and cheaper Ethereum-compatible blockchains, ensuring interoperability with other OP Stack-based chains.
• Starknet: Offers a highly customizable, cost-efficient, and fast solution, featuring a specialized language (Cairo) and sequencer (Madara) for enhanced performance and efficiency.

Critiques and Future Considerations

Arbitrum Orbits：允許任何人創建高度客製化的第3 層區塊鏈，提供無與倫比的可擴展性和易於部署性。OP Stack：提供用於構建更快、更便宜的以太坊兼容區塊鏈的工具包，確保與其他基於OP Stack 的鏈的互通性。Starknet：提供高度可自訂、經濟高效且快速的解決方案，具有專用語言(Cairo) 和排序器(Madara)，可提高性能和效率。批評和未來考慮

While L3s have gained significant traction, they are not without their critics. Some argue that they do not inherently increase transaction throughput beyond the capabilities of L2s. Others express concerns about potential dilution of Ethereum's value or increased centralization.

雖然 L3 獲得了巨大的關注，但並非沒有批評者。有些人認為，它們本身並不會增加超出 L2 能力的事務吞吐量。其他人則對以太坊價值可能被稀釋或中心化程度增加表示擔憂。

Despite these criticisms, the strategic importance of L3s in shaping the future of blockchain scalability cannot be ignored. While they may not represent the long-term solution to scaling, they offer a viable path to enhanced accessibility, diversity, and scalability in the present.

儘管有這些批評，但 L3 在塑造區塊鏈可擴展性未來方面的戰略重要性不容忽視。雖然它們可能並不代表擴展的長期解決方案，但它們提供了增強當前可訪問性、多樣性和可擴展性的可行途徑。

As full danksharding remains years away, L3s are playing a crucial role in expanding the use cases and capabilities of the blockchain ecosystem. They are not merely a stopgap measure but a transformative force that is pushing the boundaries of blockchain technology and laying the foundation for a more accessible, interoperable, and scalable future.

由於完整的 danksharding 還需要數年時間，L3 在擴展區塊鏈生態系統的用例和功能方面發揮著至關重要的作用。它們不僅僅是權宜之計，而且是一股變革力量，正在突破區塊鏈技術的界限，並為更易於訪問、可互通和可擴展的未來奠定基礎。
