以太坊 Layer-2 團隊歡迎改革區塊鏈的提案

Polygon 表示，Beam Chain 不但不會讓零知識總結變得過時，反而會讓它們運作得更好。 zkSync 建構者 Matter Labs 也看好這一點。

Two of the leading layer-2 networks operating on top of Ethereum have welcomed a recent proposal to overhaul the blockchain, dismissing suggestions that it would make their auxiliary networks redundant.

在以太坊之上運行的兩個領先的第 2 層網路對最近一項徹底改革區塊鏈的提議表示歡迎，但駁回了有關這將使它們的輔助網路變得多餘的建議。

Last week, at the biennial Devcon gathering in Bangkok, Thailand, developer Justin Drake laid out an ambitious plan to revamp Ethereum’s consensus layer architecture. As part of that plan, which has come to be known as the “Beam Chain," Drake suggested incorporating zero-knowledge cryptography, which several L2s use to compress data in order to make transactions faster and cheaper, into the Ethereum protocol.

上週，在泰國曼谷舉行的兩年一度的 Devcon 聚會上，開發人員 Justin Drake 制定了一項雄心勃勃的計劃，以改善以太坊的共識層架構。作為該計劃（後來被稱為“Beam Chain”）的一部分，Drake 建議將零知識加密技術（多個L2 使用零知識加密技術來壓縮數據，以使交易更快、更便宜）納入以太坊協議中。

Over the past few years, many in the Ethereum ecosystem have pushed a rollup-centric roadmap, meaning they would rely on layer-2 networks to overcome Ethereum’s scaling challenges. Zero-knowledge rollups specifically were seen as the superior technology because they have advantages over so-called optimistic rollups in terms of speed and security.

在過去的幾年裡，以太坊生態系統中的許多人都推動了以匯總為中心的路線圖，這意味著他們將依靠第 2 層網路來克服以太坊的擴展挑戰。零知識總結特別被視為優越的技術，因為它們在速度和安全性方面比所謂的樂觀匯總具有優勢。

Ahead of Drake’s Devcon talk, many were left wondering what the Beam Chain would mean for the zero-knowledge rollups on Ethereum, and whether they would become obsolete.

在 Drake 的 Devcon 演講之前，許多人都想知道 Beam Chain 對於以太坊上的零知識匯總意味著什麼，以及它們是否會過時。

“That's really a misconception,” said Alex Gluchowski, the CEO of Matter Labs, the developer firm behind zkSync. “The changes that Justin announced are focused on the consensus layer, not on the execution layer. It's not going to affect the execution layer.”

「這確實是一個誤解，」zkSync 背後的開發公司 Matter Labs 的執行長 Alex Gluchowski 說。 「賈斯汀宣布的改變主要集中在共識層，而不是執行層。這不會影響執行層。

Ethereum, the base layer, is itself made up of several layers. The consensus layer is responsible for ensuring that blocks are validated, while the execution layer is in charge of executing transactions. Layer-2s, which post their transaction data back to Ethereum, are mostly affected by changes on the execution layer.

以太坊作為基礎層，本身由多個層組成。共識層負責確保區塊被驗證，而執行層負責執行交易。 Layer-2 將交易資料傳回以太坊，主要受到執行層變更的影響。

In addition to incorporating ZK, Drake's proposal seeks to shorten block times, which could cut transaction costs for L2s settling on Ethereum. Drake also said he wants to introduce single-slot finality, meaning blocks with transaction data could be finalized immediately, and that information would become permanent right away. If all goes as envisioned, the Beam Chain would go live in 2029 (although Ethereum has a history of delaying ambitious technical upgrades.)

除了合併 ZK 之外，Drake 的提案還尋求縮短區塊時間，這可以降低在以太坊上結算的 L2 的交易成本。德雷克還表示，他希望引入單時隙最終確定性，這意味著帶有交易數據的區塊可以立即確定，並且這些資訊將立即成為永久性的。如果一切按設想進行，Beam Chain 將於 2029 年上線（儘管以太坊有推遲雄心勃勃的技術升級的歷史。）

“All of those things are great because we depend on Ethereum as the global settlement layer,” Gluchowski said.

「所有這些都很棒，因為我們依賴以太坊作為全球結算層，」格盧喬夫斯基說。

Glow-Up for Rollups?

捲起的發光？

Brendan Farmer, a co-founder at Polygon, also told CoinDesk he doesn’t think the Beam Chain would obsolesce layer-2s. Instead, he said, the upgrade would “make rollups work better.”

Polygon 聯合創始人 Brendan Farmer 也告訴 CoinDesk，他認為 Beam Chain 不會取代 Layer-2。相反，他表示，升級將「讓匯總工作得更好」。

“Shorter block times, faster finality, ZK verifiability of what's happening on the consensus layer – those are things that I think have a really positive impact for L2 usability and for L2 interoperability between different ecosystems,” Farmer said.

Farmer 表示：「更短的出塊時間、更快的最終確定性、共識層上發生的事情的ZK 可驗證性——我認為這些對L2 可用性和不同生態系統之間的L2 互通性具有真正積極的影響。

Faster finality on Ethereum would be especially useful for making layer-2s interoperable, a widely shared goal for scaling networks.

以太坊上更快的最終確定對於使第 2 層可互通特別有用，這是擴展網路的廣泛共同目標。

“A big problem with Ethereum right now is that for a block to be considered finalized, it generally takes 12 to 19 minutes,” Farmer said. “If you're moving funds between like Arbitrum and Polygon: until that transaction has been withdrawn from Arbitrum and deposited to Polygon, Polygon can't safely credit those funds to a user until that transaction has been finalized on the L1. So that just leads to a bad user-experience, whereas if you have 12-second finality, that becomes a better user experience.”

「目前以太坊的一個大問題是，一個區塊通常需要 12 到 19 分鐘才能被視為最終確定，」Farmer 說。 「如果您在 Arbitrum 和 Polygon 之間轉移資金：在該交易從 Arbitrum 中提取並存入 Polygon 之前，Polygon 無法安全地將這些資金貸記給用戶，直到該交易在 L1 上完成。因此，這只會導致糟糕的用戶體驗，而如果你有 12 秒的最終結果，那就會帶來更好的用戶體驗。

Gluchowski, of Matter Labs, called the Beam Chain a vindication of zero-knowledge proofs as a scaling method.

Matter Labs 的 Gluchowski 稱 Beam Chain 是對零知識證明作為擴展方法的證明。

“Using ZK really emphasizes the fact that ZK is the end game,” he said.

「使用 ZK 確實強調了 ZK 是最終遊戲的事實，」他說。
