以太坊聯合創始人 Vitalik Buterin 否認 L3 鍊是擴容解決方案

在 Layer 3 的論點中，以太坊聯合創始人 Vitalik Buterin 重申了他的立場，即這些鏈不提供擴展解決方案。他認為數據可用性限制限制了他們提高吞吐量的能力。雖然第 3 層鏈可能具有資料可用性解決方案等專門功能的潛力，但 Buterin 認為有更好的替代方案。

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

以太坊聯合創始人 Vitalik Buterin 參與 Layer 3 爭論，強調可擴展性限制和專業功能的潛在價值

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.

在圍繞以太坊第 3 層 (L3) 鏈正在進行的討論中，以太坊聯合創始人 Vitalik Buterin 明確表示，他對以太坊第 3 層 (L3) 鏈所謂的擴展解決方案的作用表示懷疑。不過，他承認 L3 可能會在以太坊生態系統中提供特定功能方面發揮作用。

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 月的部落格文章中表達的觀點，強調 L3 鏈不會為交易吞吐量提供神奇的增強。他認為，透過第 2 層 (L2) 鍊或替代方法，可以更有效地實現 L3 聲稱提供的存款和提款成本節省。

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 的評估源自於以太坊生態系內資料可用性的固有限制。 Rollups 是支撐 L2 和 L3 鏈的關鍵技術，透過定期將交易資料批量傳輸到以太坊主網或專門的資料可用性解決方案來確保資料可用性。

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，由於主網路上的儲存空間有限且昂貴，匯總通常採用資料壓縮技術來降低成本。 Buterin 強調，資料只能壓縮一次，後續的壓縮嘗試不會產生進一步的好處。因此，「匯總之上的匯總」並不能提供顯著的可擴展性優勢。

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.

儘管 Buterin 對 L3 鏈作為擴展解決方案持懷疑態度，但他承認它們可能提供有價值的專業功能。他建議 L3 可以作為 L2 鏈的資料可用性解決方案或作為注重隱私的層。然而，他警告說，這些用例仍然是推測性的，時間會告訴我們是否有更有效的方法來實現預期的結果。

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 鏈）重新點燃了人們對 Layer 3 敘事的興趣。 Buterin 的評論與圍繞 L3 的炒作形成了鮮明對比，強調需要清楚地了解它們的局限性和潛在價值。

Scalability Limitations of L3 Chains

L3 鏈的可擴展性限制

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 的懷疑源自於資料可用性和資料壓縮的基本限制。 Rollups 是 L2 和 L3 鏈的主幹，它可以批次和壓縮交易數據，以降低將其儲存在以太坊主網上的成本。然而，此壓縮過程只能執行一次。隨後對 L3 鏈的壓縮嘗試不會產生額外的好處。

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，與 L2 鏈相比，L3 鏈在可擴展性方面並未提供有意義的改進。相反，它們引入了額外的複雜性和潛在的故障點。

Potential Value of L3 Chains for Specialized Functions

L3 鏈對於專業功能的潛在價值

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:

雖然 Buterin 不認為 L3 鍊是擴展解決方案，但他承認它們在服務以太坊生態系統中的特定功能方面可能具有價值。他建議 L3 可能充當：

• 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 鏈的資料可用性解決方案：L3 可以提供更有效率、更具成本效益的方式來儲存和檢索 L2 鏈的資料。注重隱私的層：L3 可以實施零知識證明等隱私增強技術來保護使用者然而，Buterin強調，這些用例仍然是推測性的，L3 是否能夠提供比其他解決方案明顯的優勢還有待觀察。

Conclusion

結論

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 對 L3 鏈的評論在圍繞這項新興技術的炒作中提供了一個發人深省的觀點。雖然 L3 在服務專門功能方面可能具有潛在價值，但其可擴展性限制使其不適合擴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.

開發人員和研究人員應集中精力探索替代擴展解決方案，以解決資料可用性和資料壓縮的基本限制。 L2 鏈、匯總和其他創新方法在為以太坊生態系統提供可擴展且經濟高效的解決方案方面顯示出更大的前景。
