Binance首席执行官Changpeng Zhao（CZ）分享了他对L1与L2辩论的想法

CZ：第2层为AI加密提供了实用性。这意味着他们可以从已建立的L1的可靠性和安全性中受益，而不必处理保持其运行。

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的前首席执行官兼联合创始人Changpeng Zhao（CZ）分享了他对区块链世界中正在进行的辩论的想法：New AI项目是否应该构建自己的第1层（L1）或使用现有的第2层（L2）解决方案？

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.

根据CZ的说法，如果AI项目的主要重点是将区块链用于AI经济学，而不是根据区块链协议进行创新，那么在L2上进行构建可能是一个更实用的选择。

CZ: Layer 2s Offer Practicality for AI Crypto

CZ：第2层为AI加密提供实用性

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层在部署解决方案并与以太坊等平台上的活动生态系统建立联系时，具有速度和效率的优势。

“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项目的主要重点是将区块链用于AI经济学（例如，对开源AI模型的标记贡献，以及AI社区的治理）与区块链协议本身的创新，那么建立在现有L1的L2（例如，填充）上可能更实用。这样，他们就可以从已建立的L1的可靠性和安全性中受益，而不必处理它的运行。”

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.

这种想法很有趣，因为许多新项目，尤其是在像AI这样的部门中，发现他们不需要L1的全部主权。通过利用L2，他们可以获得所需的可伸缩性和安全性，成本明显降低。

Layer 1 vs. Layer 2: Key Differences Explained

第1层与第2层：解释的关键差异

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是基本区块链，例如比特币，以太坊和Solana。构建它可以完全控制其协议，共识机制和网络设置。这可能会很有吸引力，因为它代表了区块链设计的真正权力下放和完全所有权。

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解决方案（如汇总或Sidechains）在已建立的L1顶部运行。它们提供了额外的可扩展性和功能，同时取决于其构建的L1的安全性和生态系统。

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.

主要区别之一是创建和维护L1是一项艰巨的任务 - 需要建立和确保节点和验证器网络。另一方面，使用L2意味着一个项目可以跳过构建新区块链的大量工作。结果，L2项目可以利用现有的分散交易所（DEX），永久市场（PERP），开发人员工具以及更广泛的社区，该社区已经活跃于L1上。
