第三層網路：以太坊的未來是福還是禍？

在現有第 2 層 (L2) 協議之上出現第 3 層 (L3) 網路在以太坊社群內引發了爭議。雖然有些人認為 L3 提供了專門的功能並促進了擴展，但其他人則認為它們降低了以太坊的價值並損害了其安全性。 Polygon Labs 執行長 Marc Boiron 對 L3 表示懷疑，認為它們將價值從以太坊轉移到底層的 L2 上，從而損害了生態系統。

Layer-3 Networks: A Threat to Ethereum's Value or a Catalyst for Innovation?

第三層網路：對以太坊價值的威脅還是創新的催化劑？

The Ethereum ecosystem is undergoing a transformation, with the emergence of layer-3 (L3) networks sparking a heated debate within the cryptocurrency community. These innovative solutions, built atop layer-2 (L2) networks, have raised questions about their impact on Ethereum's value and the future of blockchain scaling.

以太坊生態系統正在經歷變革，第三層 (L3) 網路的出現引發了加密貨幣社群的激烈爭論。這些建構在第 2 層 (L2) 網路之上的創新解決方案引發了人們對其對以太坊價值和區塊鏈擴展未來影響的質疑。

Polygon Labs CEO's Controversial Stance

Polygon Labs 執行長的爭議立場

Marc Boiron, CEO of Polygon Labs, a leading L2 scaling network, has expressed his disapproval of L3 networks. In a recent blog post, he argued that L3s "exist only to take value away from Ethereum and onto the L2s on which the L3s are built." Boiron claims that L3s are unnecessary for scaling existing networks and that they could compromise Ethereum's security and overall value.

領先的 L2 擴展網絡 Polygon Labs 的首席執行官 Marc Boiron 表達了他對 L3 網絡的不滿。在最近的一篇部落格文章中，他認為 L3「存在只是為了將價值從以太坊轉移到構建 L3 的 L2 上」。 Boiron 聲稱 L3 對於擴展現有網路來說是不必要的，而且它們可能會損害以太坊的安全性和整體價值。

"I'll say the quiet part out loud: L3s exist only to take value away from Ethereum and onto the L2s on which the L3s are built," wrote Boiron. "You do not need L3s to scale."

「我要大聲說出安靜的部分：L3 的存在只是為了將價值從以太坊轉移到構建 L3 的 L2 上，」Boiron 寫道。 “你不需要 L3 來擴展。”

Boiron's comments have ignited a fiery debate, with proponents and detractors alike weighing in on the merits of L3 networks.

Boiron 的言論引發了一場激烈的爭論，支持者和反對者都對 L3 網路的優點進行了權衡。

The Benefits of L3 Networks

L3 網路的好處

Supporters of L3 networks argue that they offer several advantages that L2s cannot provide. Peter Haymond, senior partnership manager at Offchain Labs, highlighted the cost-effectiveness of native bridging from L2 rather than L1, the affordability of proving on-chain, the use of custom gas tokens, and specialized state transition functions as key benefits of L3s.

L3 網路的支持者認為，它們提供了 L2 無法提供的多項優勢。 Offchain Labs 的高級合作夥伴經理Peter Haymond 強調了L2 而不是L1 的本機橋接的成本效益、鏈上證明的可負擔性、自定義Gas 代幣的使用以及專門的狀態轉換功能，這些都是L3 的主要優勢。

Arbitrum Foundation researcher Patrick McCorry expressed surprise at Boiron's viewpoint, emphasizing the significant advantages offered by L3s, particularly their ability to enable L2s to evolve into settlement layers. This, McCorry argues, reduces the cost of executing bridges and allows Ethereum to serve as a global ordering service and final arbiter of settlements.

Arbitrum 基金會研究員 Patrick McCorry 對 Boiron 的觀點表示驚訝，強調 L3 提供的顯著優勢，特別是它們使 L2 演變成結算層的能力。麥考裡認為，這降低了執行橋樑的成本，並使以太坊能夠充當全球訂購服務和結算的最終仲裁者。

Vitalik Buterin's Perspective

Vitalik Buterin 的觀點

The debate over L3 networks was initially sparked by Ethereum co-founder Vitalik Buterin in late 2022. Buterin acknowledged the potential value of L3s, but emphasized that they should offer unique functions not provided by L2s.

關於 L3 網路的爭論最初是由以太坊聯合創始人 Vitalik Buterin 在 2022 年底引發的。Buterin 承認 L3 的潛在價值，但強調它們應該提供 L2 不提供的獨特功能。

"A third layer on the blockchain would only be justified if it introduced unique functions not provided by layer-2s," Buterin wrote.

Buterin 寫道：“區塊鏈上的第三層只有引入第 2 層未提供的獨特功能才是合理的。”

The Future of L3 Networks

L3 網路的未來

Despite the debate and differing opinions, the L3 ecosystem continues to grow and evolve. Orbs, zkSync Hyperchains, Xai, and Degen Chain are among the leading players in this emerging space. However, the sector remains relatively small, with only four L3 tokens currently listed on CoinGecko.

儘管存在爭論和不同意見，L3 生態系統仍在不斷發展和發展。 Orbs、zkSync Hyperchains、Xai 和 Degen Chain 是這個新興領域的領先參與者。然而，該行業仍然相對較小，目前只有四種 L3 代幣在 CoinGecko 上上市。

Whether or not L3 networks will ultimately detract from Ethereum's value remains to be seen. The ongoing debate highlights the dynamic and ever-evolving nature of the blockchain industry. As the technology matures and new applications are developed, the role of L3 networks within the Ethereum ecosystem will undoubtedly continue to be a topic of discussion and debate.

L3 網路最終是否會降低以太坊的價值還有待觀察。持續不斷的爭論凸顯了區塊鏈產業的動態和不斷發展的本質。隨著技術的成熟和新應用的開發，L3網路在以太坊生態系統中的作用無疑將繼續成為討論和爭論的話題。
