Binance首席執行官Changpeng Zhao（CZ）分享了他對L1與L2辯論的想法

CZ：第2層為AI加密提供了實用性。這意味著他們可以從已建立的L1的可靠性和安全性中受益，而不必處理保持其運行。

Changpeng Zhao (CZ), the former CEO and co-founder of Binance, shared his thoughts on the ongoing debate in the blockchain world: should new AI projects build their own Layer 1 (L1) or use an existing Layer 2 (L2) solution?

Binance的前首席執行官兼聯合創始人Changpeng Zhao（CZ）分享了他對區塊鏈世界中正在進行的辯論的想法：New AI項目是否應該構建自己的第1層（L1）或使用現有的第2層（L2）解決方案？

According to CZ, if an AI project’s main focus is to utilize blockchain for AI economics rather than innovating on the blockchain protocol, then building on an L2 can be a more practical choice.

根據CZ的說法，如果AI項目的主要重點是將區塊鏈用於AI經濟學，而不是根據區塊鏈協議進行創新，那麼在L2上進行構建可能是一個更實用的選擇。

CZ: Layer 2s Offer Practicality for AI Crypto

CZ：第2層為AI加密提供實用性

He notes that Layer 2s offer the advantage of speed and efficiency in deploying solutions and connecting with the active ecosystem on platforms like Ethereum.

他指出，第2層在部署解決方案並與以太坊等平台上的活動生態系統建立聯繫時，具有速度和效率的優勢。

“If an AI project's main focus is to use blockchain for AI economics (e.g., tokenized contributions to open-source AI models, and governance of the AI community) vs. innovating on the blockchain protocol itself, then it may be more practical to build on an L2 (e.g., rollup) of an existing L1. This way, they can benefit from the reliability and security of an established L1 without having to deal with keeping it running.”

“如果AI項目的主要重點是將區塊鏈用於AI經濟學（例如，對開源AI模型的標記貢獻，以及AI社區的治理）與區塊鏈協議本身的創新，那麼建立在現有L1的L2（例如，填充）上可能更實用。這樣，他們就可以從已建立的L1的可靠性和安全性中受益，而不必處理它的運行。”

This thought is interesting as many new projects, especially in sectors like AI, are finding that they do not need the full sovereignty of an L1. They can get the required scalability and security with significantly lower costs by leveraging an L2.

這種想法很有趣，因為許多新項目，尤其是在像AI這樣的部門中，發現他們不需要L1的全部主權。通過利用L2，他們可以獲得所需的可伸縮性和安全性，成本明顯降低。

Layer 1 vs. Layer 2: Key Differences Explained

第1層與第2層：解釋的關鍵差異

An L1 is the base blockchain, such as Bitcoin, Ethereum, and Solana. Building it gives a project full control over its protocol, consensus mechanism, and network settings. This can be appealing because it represents true decentralization and complete ownership of the blockchain’s design.

L1是基本區塊鏈，例如比特幣，以太坊和Solana。構建它可以完全控制其協議，共識機制和網絡設置。這可能會很有吸引力，因為它代表了區塊鏈設計的真正權力下放和完全所有權。

On the other hand, L2 solutions (like rollups or sidechains) operate on top of an established L1. They provide additional scalability and functionality while depending on the security and ecosystem of the L1 they are built on.

另一方面，L2解決方案（如匯總或Sidechains）在已建立的L1頂部運行。它們提供了額外的可擴展性和功能，同時取決於其構建的L1的安全性和生態系統。

One of the main differences is that creating and maintaining an L1 is a massive undertaking—one that requires setting up and securing a network of nodes and validators. On the other hand, using an L2 means a project can skip the large amount of work of building a new blockchain. As a result, L2 projects can tap into existing decentralized exchanges (DEXs), perpetual markets (perps), developer tools, and a broader community that is already active on the L1.

主要區別之一是創建和維護L1是一項艱鉅的任務 - 需要建立和確保節點和驗證器網絡。另一方面，使用L2意味著一個項目可以跳過構建新區塊鏈的大量工作。結果，L2項目可以利用現有的分散交易所（DEX），永久市場（PERP），開發人員工具以及更廣泛的社區，該社區已經活躍於L1上。
