以太坊第 3 層鏈：平衡風險與創新

Polygon Labs 執行長 Marc Boiron 引發了關於以太坊第 3 層鏈的安全影響的爭論。 Boiron 認為，這些鏈可能會危及以太坊的安全，因為它們在第 2 層鏈上而不是直接在主網上結算交易。然而，第 3 層鏈的支持者，如 Offchain Labs 的 Peter Haymond，強調了它們的好處，例如較低的橋接成本和更容易實現專門功能。儘管討論仍在繼續，但以太坊第 3 層生態系統仍處於新生階段，目前只有少數項目在 CoinGecko 上列出。

Ethereum Layer 3 Chains: A Potential Security Risk or a Catalyst for Innovation?

以太坊第 3 層鏈：潛在的安全風險還是創新的催化劑？

Driven by the urgent need for scalability, Ethereum has witnessed a surge in Layer 2 (L2) chains, blockchains operating atop the network to facilitate off-chain transaction processing and subsequent settlement on the mainnet. As this rollup-centric approach continues to gain momentum, a new variant has emerged: Layer 3 (L3) chains.

在對可擴展性的迫切需求的推動下，以太坊見證了第 2 層 (L2) 鏈的激增，這些區塊鏈在網路之上運行，以促進鏈下交易處理和隨後在主網上的結算。隨著這種以總結為中心的方法不斷獲得動力，出現了一個新的變體：第 3 層 (L3) 鏈。

L3 chains, akin to L2 rollups, execute transactions off the Ethereum mainnet. However, instead of finalizing these transactions on the mainnet, they are settled on an L2 chain. This layering concept has sparked a heated debate, particularly regarding its potential impact on Ethereum's security.

L3 鏈類似於 L2 匯總，在以太坊主網上執行交易。然而，這些交易不是在主網上完成，而是在 L2 鏈上結算。這種分層概念引發了激烈的爭論，特別是關於它對以太坊安全的潛在影響。

Polygon Labs CEO Marc Boiron's Concerns

Polygon Labs 執行長 Marc Boiron 的擔憂

Marc Boiron, CEO of Polygon Labs, has voiced his apprehensions about the security risks posed by L3 chains. In a series of recent posts, Boiron expressed his belief that L3 chains could potentially undermine Ethereum's security by diverting fees and diminishing the value of ETH.

Polygon Labs 執行長 Marc Boiron 表達了他對 L3 鏈帶來的安全風險的擔憂。在最近的一系列貼文中，Boiron 表達了他的信念，L3 鏈可能會透過轉移費用和降低 ETH 的價值來破壞以太坊的安全。

Boiron highlighted the extreme scenario of all L3 chains settling on a single L2 chain, which, in his view, could lead to a significant decline in Ethereum's value. With no viable fee-earning model beyond minimal fees charged by the single L2, Boiron argues that validators would lose incentive to hold ETH and secure the network.

Boiron 強調了所有 L3 鏈都定居在一條 L2 鏈上的極端情況，他認為這可能會導致以太坊價值大幅下跌。 Boiron 認為，除了單一 L2 收取的最低費用之外，沒有可行的收費模式，驗證者將失去持有 ETH 和保護網路安全的動機。

Offchain Labs' Defense of L3 Chains

Offchain Labs 對 L3 鏈的防禦

In response to Boiron's concerns, Peter Haymond, Senior Partnerships Manager at Offchain Labs, the developers behind the Arbitrum network, presented a contrasting perspective. Haymond asserted that L3 chains offer a multitude of benefits, including reduced bridging and proving costs, the use of custom gas tokens, and simplified implementation of specialized state transition functions.

為了回應 Boiron 的擔憂，Arbitrum 網路背後的開發商 Offchain Labs 的高級合作夥伴經理 Peter Haymond 提出了相反的觀點。 Haymond 斷言，L3 鏈具有多種優勢，包括降低橋接和證明成本、使用自訂 Gas 代幣以及簡化專門狀態轉換功能的實作。

Haymond countered Boiron's claim that these advantages could be achieved with Polygon-powered L2 chains, arguing that only one benefit, namely the low cost of native bridging, was truly exclusive to L3 chains.

Haymond 反駁了 Boiron 的說法，即這些優勢可以透過 Polygon 驅動的 L2 鏈來實現，他認為只有一個好處，即本地橋接的低成本，是真正 L3 鏈獨有的。

Ongoing Debate and Emerging Ecosystem

持續的爭論和新興的生態系統

Despite these divergent views, the Ethereum L3 ecosystem remains in its nascent stages. At the time of writing, CoinGecko lists only four projects in this category: Degen, Xai, Orbs, and Dream Machine Token.

儘管有這些不同的觀點，以太坊 L3 生態系統仍處於初期階段。截至撰寫本文時，CoinGecko 僅列出了該類別中的四個項目：Degen、Xai、Orbs 和 Dream Machine Token。

In September 2022, Ethereum co-founder Vitalik Buterin emphasized that L3 networks are effective only when they serve a distinct purpose from the L2 chain. The recently launched Degen L3 network has gained significant adoption, boasting millions of dollars in trading volume.

2022 年 9 月，以太坊聯合創始人 Vitalik Buterin 強調，L3 網路只有在服務 L2 鏈的明確目的時才有效。最近推出的 Degen L3 網路已被廣泛採用，交易量達到數百萬美元。

Implications for Ethereum's Future

The ongoing debate surrounding Ethereum L3 chains highlights the complex and evolving nature of the blockchain ecosystem. The potential risks and benefits associated with these novel solutions require thorough consideration. As the Ethereum community grapples with these issues, the future direction of these technologies and their impact on the broader Ethereum network remain uncertain.

圍繞以太坊 L3 鏈的持續爭論凸顯了區塊鏈生態系統的複雜性和不斷發展的本質。需要仔細考慮與這些新穎解決方案相關的潛在風險和效益。隨著以太坊社群努力解決這些問題，這些技術的未來方向及其對更廣泛的以太坊網路的影響仍然不確定。

This discourse provides valuable insights for users seeking a deeper understanding of the emerging narratives within the cryptocurrency space. By examining the arguments presented by both proponents and detractors of Ethereum L3 chains, individuals can form informed opinions on the potential implications of these technologies.

本文為尋求更深入了解加密貨幣領域新興敘事的使用者提供了寶貴的見解。透過研究以太坊 L3 鏈的支持者和反對者提出的論點，個人可以對這些技術的潛在影響形成明智的意見。

As the Ethereum ecosystem continues to evolve, it is crucial to remain engaged with these debates and developments to make informed decisions and navigate the complexities of this rapidly changing landscape.

隨著以太坊生態系統的不斷發展，至關重要的是繼續參與這些辯論和發展，以做出明智的決策並應對這一快速變化的環境的複雜性。
