ANZA引入了新的Alpenglow共識協議，旨在使Solana網絡更快，更確定性

Alpenglow是一種新的共識協議，是由以索拉納（Solana）為中心的研究與開發公司Anza提出的。它旨在使網絡更快，更確定性和更安全。

Anza, a Solana-focused research and development firm, has unveiled a new consensus protocol named Alpenglow. This protocol aims to make the Solana network faster, more deterministic, and safer. Described as the biggest consensus redesign since Solana’s launch, Alpenglow is set to replace the existing TowerBFT (Byzantine Fault Tolerance) mechanism and Proof of History with a more easily understandable and efficient system.

以索拉納（Solana）為重點的研究與開發公司Anza揭示了一項名為Alpenglow的新共識協議。該協議旨在使Solana網絡更快，更確定性和更安全。被描述為自Solana推出以來最大的共識重新設計，Alpenglow將用更容易理解和高效的系統來替換現有的TowerBft（拜占庭容錯）機制和歷史證明。

In his X post, Yakovenko further stated that he got nearly everything wrong about consensus, except the important parts. Drawing attention to the design of Alpenglow, he highlighted two critical requirements:

Yakovenko在他的X帖子中進一步表示，除了重要的部分，他幾乎對共識幾乎所有錯誤。引起人們對Alpenglow的設計的關注，他強調了兩個關鍵要求：

* Consensus should not interfere with block producers using 100% of the available bandwidth at all times.

*共識不應始終使用100％的可用帶寬來干擾塊生產商。

* Users must experience deterministic finality in a single round.

*用戶必須在一輪中經歷確定性的終結性。

According to Anza’s blog, Alpenglow drastically reduces transaction finality latency to a median of 100-150 ms. In contrast, TowerBFT takes roughly 12.8 seconds from block creation until finality. This marks a 100x improvement, rendering it competitive with centralized infrastructure.

根據Anza的博客，Alpenglow將交易最終延遲延遲大大減少到中位數為100-150毫秒。相比之下，TowerBft從Block Creation到最終結束大約需要12.8秒。這標誌著100倍的改善，使其在集中基礎設施中具有競爭力。

Alpenglow achieves this by splitting the faults into two categories: full Byzantine and down or unavailable. Based on this fault model, the protocol can guarantee safe finality within one or two rounds. If a fork accumulates 40% of the total stake in votes (20% Byzantine and 20% down), then the node can safely commit to it. The fork will be finalized either in one round with 80% of votes or in two rounds with 60%.

Alpenglow通過將故障分為兩個類別來實現這一目標：完整的拜占庭和下降或不可用。基於此故障模型，該協議可以保證一兩輪內的安全終端。如果叉子積累了投票總股份的40％（拜占庭式20％和20％下降），則節點可以安全地承諾。叉子將以80％的選票或兩輪為60％在一輪中最終確定。

This approach allows for deterministic finality without slowing down block production. Instead of handling epochs full of unconfirmed blocks, Alpenglow reduces the active state to just two blocks. This simplifies the system for developers and validators, especially when different parts of the network aren't perfectly synchronized.

這種方法允許確定性終結性，而不會減慢塊生產。 Alpenglow並沒有處理充滿未經證實的塊的時代，而是將活動狀態減少到只有兩個塊。這簡化了開發人員和驗證器的系統，尤其是當網絡的不同部分未完全同步時。

Yakovenko also noted that the protocol has simplified and formalized Turbine, now renamed Rotor. Together with Votor, Alpenglow's voting component, these components lay the foundation for enhancing scalability features, such as support for multiple concurrent leaders and increased validator efficiency.

Yakovenko還指出，該協議已簡化和形式化的渦輪機，現在更名為轉子。這些組件與Alpenglow的投票組成部分一起，為增強可擴展性功能（例如支持多個並發領導者的支持和提高驗證者效率）奠定了基礎。

Although still a proposal, if approved, Alpenglow could be a major step in Solana's ongoing evolution.

儘管仍然是一項提議，如果獲得批准，Alpenglow可能是Solana持續發展的重要一步。
