以太坊 Layer-2 团队欢迎改革区块链的提案

Polygon 表示，Beam Chain 不但不会让零知识汇总变得过时，反而会让它们工作得更好。 zkSync 构建者 Matter Labs 也看好这一点。

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.

在以太坊之上运行的两个领先的第 2 层网络对最近一项彻底改革区块链的提议表示欢迎，但驳回了有关这将使它们的辅助网络变得多余的建议。

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.

上周，在泰国曼谷举行的两年一度的 Devcon 聚会上，开发人员 Justin Drake 制定了一项雄心勃勃的计划，以改进以太坊的共识层架构。作为该计划（后来被称为“Beam Chain”）的一部分，Drake 建议将零知识加密技术（多个 L2 使用零知识加密技术来压缩数据，以使交易更快、更便宜）纳入以太坊协议中。

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.

在过去的几年里，以太坊生态系统中的许多人都推动了以汇总为中心的路线图，这意味着他们将依靠第 2 层网络来克服以太坊的扩展挑战。零知识汇总特别被视为优越的技术，因为它们在速度和安全性方面比所谓的乐观汇总具有优势。

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 演讲之前，许多人都想知道 Beam Chain 对于以太坊上的零知识汇总意味着什么，以及它们是否会过时。

“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.”

“这确实是一个误解，”zkSync 背后的开发公司 Matter Labs 的首席执行官 Alex Gluchowski 说。 “贾斯汀宣布的改变主要集中在共识层，而不是执行层。这不会影响执行层。”

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.

以太坊作为基础层，本身由多个层组成。共识层负责确保区块被验证，而执行层负责执行交易。 Layer-2 将交易数据发送回以太坊，主要受到执行层变化的影响。

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.)

除了合并 ZK 之外，Drake 的提案还寻求缩短出块时间，这可以降低在以太坊上结算的 L2 的交易成本。德雷克还表示，他希望引入单时隙最终确定性，这意味着带有交易数据的区块可以立即确定，并且该信息将立即成为永久性的。如果一切按设想进行，Beam Chain 将于 2029 年上线（尽管以太坊有推迟雄心勃勃的技术升级的历史。）

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

“所有这些都很棒，因为我们依赖以太坊作为全球结算层，”格卢乔夫斯基说。

Glow-Up for Rollups?

卷起的发光？

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 联合创始人 Brendan Farmer 也告诉 CoinDesk，他认为 Beam Chain 不会取代 Layer-2。相反，他表示，升级将“让汇总工作得更好”。

“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：“更短的出块时间、更快的最终确定性、共识层上发生的事情的 ZK 可验证性——我认为这些对 L2 可用性和不同生态系统之间的 L2 互操作性具有真正积极的影响。”

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

以太坊上更快的最终确定对于使第 2 层可互操作特别有用，这是扩展网络的广泛共同目标。

“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.”

“目前以太坊的一个大问题是，一个区块通常需要 12 到 19 分钟才能被视为最终确定，”Farmer 说。 “如果您在 Arbitrum 和 Polygon 之间转移资金：在该交易从 Arbitrum 中提取并存入 Polygon 之前，Polygon 无法安全地将这些资金贷记给用户，直到该交易在 L1 上完成。因此，这只会导致糟糕的用户体验，而如果你有 12 秒的最终结果，那就会带来更好的用户体验。”

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

Matter Labs 的 Gluchowski 称 Beam Chain 是对零知识证明作为扩展方法的证明。

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

“使用 ZK 确实强调了 ZK 是最终游戏的事实，”他说。
