在 DevCon 2024 上，与会者热切期待有关以太坊未来的最新消息。其中一项公告是以太坊核心开发人员 Justin Drake 提出的一项提案，旨在为网络建立一个新的共识层，称为“Beam Chain”。以下是一个快速常见问题解答，可帮助您了解该提案：

What is Beam Chain?

什么是梁链？

Beam Chain is a proposal to redesign Ethereum's consensus layer, announced by Justin Drake at DevCon. The goal is to align Ethereum with the latest blockchain research for better scalability, security, and performance. Specifically, Beam Chain will focus on improving block production, staking mechanisms, and cryptography.

Beam Chain 是 Justin Drake 在 DevCon 上宣布的一项重新设计以太坊共识层的提案。目标是使以太坊与最新的区块链研究保持一致，以实现更好的可扩展性、安全性和性能。具体来说，Beam Chain 将专注于改进区块生产、质押机制和密码学。

Why is Beam Chain needed?

为什么需要梁链？

The current Beacon Chain was introduced during Ethereum's transition to Proof-of-Stake, making it about five years old. While Beacon is still effective, these years have brought technical debt and limitations. For instance, Beacon was designed before bleeding-edge decentralized systems advancements, such as zero-knowledge proofs (ZK proofs), could be integrated.

当前的信标链是在以太坊向权益证明过渡期间引入的，距今已有五年左右的历史。虽然 Beacon 仍然有效，但这些年来带来了技术债务和限制。例如，Beacon 是在集成零知识证明（ZK 证明）等尖端去中心化系统进步之前设计的。

Beam Chain aims to modernize Ethereum's consensus layer for the next decade, incorporating these advancements and setting the stage for further innovation.

Beam Chain 的目标是在未来十年实现以太坊共识层的现代化，整合这些进步并为进一步创新奠定基础。

Does Beam Chain introduce a new token or network?

Beam Chain 是否引入了新的代币或网络？

No. Beam Chain does not create a new token or network. It builds on Ethereum's existing infrastructure, keeping the same ETH ticker and ecosystem.

不会。Beam Chain 不会创建新的代币或网络。它建立在以太坊现有的基础设施之上，保持相同的以太坊代码和生态系统。

What are the key upgrades in Beam Chain?

Beam Chain 的主要升级有哪些？

Beam Chain proposes several key upgrades to improve Ethereum's consensus layer:

Beam Chain 提出了几项关键升级来改进以太坊的共识层：

Block production: To enhance censorship resistance, Beam Chain will introduce inclusion lists and execution auctions. It will also decrease the time slots for faster transactions.

区块生产：为了增强审查阻力，Beam Chain将引入包含列表和执行拍卖。它还将减少更快交易的时间段。

Staking: Beam Chain aims to lower the validator entry point from 32 ETH to 1 ETH, making staking more accessible. Additionally, it will introduce better issuance models.

质押：Beam Chain 的目标是将验证者的入口点从 32 ETH 降低到 1 ETH，使质押变得更容易。此外，还将引入更好的发行模式。

Cryptography: For enhanced security, Beam Chain will integrate ZK proofs, quantum-resistant cryptography, and aggregatable signatures.

密码学：为了增强安全性，Beam Chain 将集成 ZK 证明、抗量子密码学和可聚合签名。

How will Beam Chain impact Ethereum Layer 2 (L2) chains like Polygon zkEVM? What about the AggLayer?

Beam Chain 将如何影响 Polygon zkEVM 等以太坊第 2 层 (L2) 链？那么 AggLayer 呢？

Since the Beam Chain proposes adding ZK to Ethereum itself, there are potential impacts on Polygon zkEVM and the AggLayer:

由于 Beam Chain 提议将 ZK 添加到以太坊本身，因此对 Polygon zkEVM 和 AggLayer 存在潜在影响：

Faster settlement: Single-slot finality reduces settlement delays for L2 (Polygon zkEVM), but it can also benefit Agglayer moving forward.

更快的结算：单时隙最终性减少了 L2 (Polygon zkEVM) 的结算延迟，但它也有利于 Agglayer 的发展。

Lower costs: Faster slots and improved block processing will reduce transaction costs for L2s settling on Ethereum, which can impact how proofs are processed.

更低的成本：更快的插槽和改进的块处理将降低在以太坊上结算的 L2 的交易成本，这可能会影响证明的处理方式。

Enhanced security: Native ZK proof integration strengthens rollups like Polygon zkEVM. Better security = better security. Duh.

增强的安全性：原生 ZK 证明集成增强了 Polygon zkEVM 等汇总功能。更好的安全性=更好的安全性。呃。

Reduced MEV risks: Better censorship resistance minimizes Maximal Extractable Value risks, benefiting L2 ecosystems.

降低 MEV 风险：更好的审查阻力可最大限度地降低最大可提取价值风险，有利于 L2 生态系统。

Future-proofing: Post-quantum cryptography will ensure a robust foundation for L2 innovation, accelerating internal research.

面向未来：后量子密码学将确保为 L2 创新奠定坚实的基础，加速内部研究。

When will Beam Chain be implemented?

Beam Chain什么时候上线？

Here's the proposed roadmap:

以下是建议的路线图：

But keep an eye on the Ethereum research forum for the latest.

但请密切关注以太坊研究论坛的最新动态。

Is Beam Chain Ethereum 3.0?

Beam Chain是以太坊3.0吗？

No. Beam Chain focuses only on Ethereum's consensus layer. It is not a rebranding of Ethereum or a new iteration like "Ethereum 3.0." Instead, it aligns with Ethereum's existing roadmap and accelerates specific components.

不。Beam Chain 只关注以太坊的共识层。它不是以太坊的品牌重塑，也不是“以太坊 3.0”之类的新迭代。相反，它与以太坊现有的路线图保持一致并加速特定组件。

How will Beam Chain impact decentralization?

Beam Chain 将如何影响去中心化？

Beam Chain balances performance with decentralization by maintaining compatibility with validators on standard hardware, even in regions with high-latency Internet connections.

Beam Chain 通过保持与标准硬件上验证器的兼容性，平衡性能与去中心化，即使在互联网连接高延迟的地区也是如此。

Best of all, lowering the staking requirement to 1 ETH will further democratize participation in securing the network.

最重要的是，将质押要求降低至 1 ETH 将进一步使网络安全的参与更加民主化。

What role do zero-knowledge proofs play in Beam Chain?

零知识证明在Beam Chain中扮演什么角色？

Beam Chain integrates ZK proofs to enable a real-time validation of the consensus layer and unlock improved scalability and security.

Beam Chain 集成了 ZK 证明，可以实时验证共识层并提高可扩展性和安全性。

Overall, this integration enhances support for technologies like zkEVMs, better enabling Ethereum's ability to scale while maintaining decentralization.

总体而言，这种集成增强了对 zkEVM 等技术的支持，更好地使以太坊能够在保持去中心化的同时进行扩展。

What's the long-term vision for Beam Chain?

Beam Chain 的长期愿景是什么？

Beam Chain aims to put Ethereum's consensus layer into "maintenance mode" by addressing technical debt and implementing long-term solutions like quantum resistance. This ensures Ethereum remains secure, efficient, and adaptable for decades to come, enabling future innovation without the need for disruptive redesigns.

Beam Chain 旨在通过解决技术债务和实施量子电阻等长期解决方案，将以太坊的共识层置于“维护模式”。这确保了以太坊在未来几十年内保持安全、高效和适应性，从而无需进行颠覆性的重新设计即可实现未来的创新。
