以太坊联合创始人 Vitalik Buterin 否认 L3 链是扩容解决方案

在 Layer 3 的争论中，以太坊联合创始人 Vitalik Buterin 重申了他的立场，即这些链不提供扩展解决方案。他认为数据可用性限制限制了他们提高吞吐量的能力。虽然第 3 层链可能具有数据可用性解决方案等专门功能的潜力，但 Buterin 认为存在更好的替代方案。

Ethereum Co-Founder Vitalik Buterin Weighs In on the Layer 3 Debate, Underscoring Scalability Limitations and Potential Value for Specialized Functions

以太坊联合创始人 Vitalik Buterin 参与 Layer 3 争论，强调可扩展性限制和专业功能的潜在价值

In the ongoing discourse surrounding Ethereum Layer 3 (L3) chains, Ethereum co-founder Vitalik Buterin has unequivocally asserted his skepticism towards their purported role as scaling solutions. However, he acknowledges that L3s may find utility in serving specific functions within the Ethereum ecosystem.

在围绕以太坊第 3 层 (L3) 链正在进行的讨论中，以太坊联合创始人 Vitalik Buterin 明确表示，他对以太坊第 3 层 (L3) 链所谓的扩展解决方案的作用表示怀疑。不过，他承认 L3 可能会在以太坊生态系统中提供特定功能方面发挥作用。

Reiterating his views expressed in a September 2022 blog post, Buterin emphasizes that L3 chains do not offer magical enhancements to transaction throughput. He contends that the cost savings on deposits and withdrawals that L3s purport to provide can be more efficiently achieved through Layer 2 (L2) chains or alternative methods.

Buterin 重申了他在 2022 年 9 月的博客文章中表达的观点，强调 L3 链不会为交易吞吐量提供神奇的增强。他认为，通过第 2 层 (L2) 链或替代方法，可以更有效地实现 L3 声称提供的存款和取款成本节省。

Buterin's assessment stems from the inherent limitations of data availability within the Ethereum ecosystem. Rollups, a key technology underpinning L2 and L3 chains, ensure data availability by periodically batching transaction data to the Ethereum mainnet or to specialized data availability solutions.

Buterin 的评估源于以太坊生态系统内数据可用性的固有局限性。 Rollups 是支撑 L2 和 L3 链的关键技术，通过定期将交易数据批量传输到以太坊主网或专门的数据可用性解决方案来确保数据可用性。

However, due to the limited and expensive storage space on the mainnet, rollups typically employ data compression techniques to reduce costs. Buterin highlights that data can only be compressed once, and subsequent compression attempts yield no further benefits. Consequently, "rollups on top of rollups" do not provide significant scalability advantages.

然而，由于主网上的存储空间有限且昂贵，汇总通常采用数据压缩技术来降低成本。 Buterin 强调，数据只能压缩一次，后续的压缩尝试不会产生进一步的好处。因此，“汇总之上的汇总”并不能提供显着的可扩展性优势。

Despite his skepticism towards L3 chains as scaling solutions, Buterin acknowledges that they may serve valuable specialized functions. He suggests that L3s could potentially serve as data availability solutions for L2 chains or as privacy-focused layers. However, he cautions that these use cases remain speculative, and time will tell if there are more efficient ways to achieve the desired outcomes.

尽管 Buterin 对 L3 链作为扩展解决方案持怀疑态度，但他承认它们可能提供有价值的专业功能。他建议 L3 可以作为 L2 链的数据可用性解决方案或作为注重隐私的层。然而，他警告说，这些用例仍然是推测性的，时间会告诉我们是否有更有效的方法来实现预期的结果。

The recent launch of Degen, a Layer 3 chain on the Coinbase-incubated Layer 2 Base, has reignited interest in the Layer 3 narrative. Buterin's comments provide a counterpoint to the hype surrounding L3s, emphasizing the need for a clear understanding of their limitations and potential value.

最近推出的 Degen（Coinbase 孵化的 Layer 2 Base 上的 Layer 3 链）重新点燃了人们对 Layer 3 叙事的兴趣。 Buterin 的评论与围绕 L3 的炒作形成了鲜明对比，强调需要清楚地了解它们的局限性和潜在价值。

Scalability Limitations of L3 Chains

L3 链的可扩展性限制

Buterin's skepticism stems from the fundamental constraints of data availability and data compression. Rollups, the backbone of both L2 and L3 chains, batch and compress transaction data to reduce the cost of storing it on the Ethereum mainnet. However, this compression process can only be performed once. Subsequent compression attempts on L3 chains do not yield additional benefits.

Buterin 的怀疑源于数据可用性和数据压缩的基本限制。 Rollups 是 L2 和 L3 链的主干，它可以批处理和压缩交易数据，以降低将其存储在以太坊主网上的成本。然而，该压缩过程只能执行一次。随后对 L3 链的压缩尝试不会产生额外的好处。

As a result, L3 chains do not offer a meaningful improvement in scalability over L2 chains. Instead, they introduce additional layers of complexity and potential points of failure.

因此，与 L2 链相比，L3 链在可扩展性方面并未提供有意义的改进。相反，它们引入了额外的复杂性和潜在的故障点。

Potential Value of L3 Chains for Specialized Functions

L3 链对于专业功能的潜在价值

While Buterin dismisses L3 chains as scaling solutions, he acknowledges that they may have value in serving specific functions within the Ethereum ecosystem. He suggests that L3s could potentially serve as:

虽然 Buterin 不认为 L3 链是扩展解决方案，但他承认它们在服务以太坊生态系统中的特定功能方面可能具有价值。他建议 L3 可能充当：

• Data availability solutions for L2 chains: L3s could provide a more efficient and cost-effective way to store and retrieve data for L2 chains.
• Privacy-focused layers: L3s could implement privacy-enhancing technologies, such as zero-knowledge proofs, to protect user transactions from being tracked or surveilled.

However, Buterin emphasizes that these use cases remain speculative, and it remains to be seen whether L3s can offer a clear advantage over alternative solutions.

L2 链的数据可用性解决方案：L3 可以提供更高效、更具成本效益的方式来存储和检索 L2 链的数据。注重隐私的层：L3 可以实施零知识证明等隐私增强技术来保护用户然而，Buterin 强调，这些用例仍然是推测性的，L3 是否能够提供比其他解决方案明显的优势还有待观察。

Conclusion

结论

Vitalik Buterin's comments on L3 chains provide a sobering perspective amidst the hype surrounding this emerging technology. While L3s may have potential value in serving specialized functions, their scalability limitations make them unsuitable for the primary purpose of scaling Ethereum.

Vitalik Buterin 对 L3 链的评论在围绕这项新兴技术的炒作中提供了一个发人深省的观点。虽然 L3 在服务专门功能方面可能具有潜在价值，但其可扩展性限制使其不适合扩展以太坊的主要目的。

Developers and researchers should focus their efforts on exploring alternative scaling solutions that address the fundamental constraints of data availability and data compression. L2 chains, rollups, and other innovative approaches show greater promise in providing scalable and cost-effective solutions for the Ethereum ecosystem.

开发人员和研究人员应集中精力探索替代扩展解决方案，以解决数据可用性和数据压缩的基本限制。 L2 链、汇总和其他创新方法在为以太坊生态系统提供可扩展且经济高效的解决方案方面显示出更大的前景。
