优化栈的每一层，为交易提供不可比拟的优势 Optimizing every layer of the stack to give exchanges an unfair advantage

Sei is the first Layer 1 blockchain designed for trading

Sei 是第一个为交易而设计的 Layer 1 区块链

Sei是什么 (What is Sei?)

Most Layer 1's fall into two extremes - with general purpose chains on one end (Solana, Ethereum) and app-specific chains on the other (dYdX, Osmosis). Sei unlocks an entirely new design space between the two—not general-purpose nor app-specific, but use case-specific, which enables Sei to create an environment custom-built for DEX applications.

大多数Layer 1 分为两个极端——一端是通用链（Solana、以太坊），另一端是特定应用链（dYdX、Osmosis）。 Sei 在两者之间开辟了一个全新的设计空间——既不是通用的也不是特定应用的，而是特定用例的，这使 Sei 能够创建一个为 DEX 应用定制的环境。

By exploring the new design space in between app-chains and general purpose Layer 1's, Sei has carefully selected for a unique set of tradeoffs that make its Layer 1 the optimal environment for DEXs. Designed from bottoms-up to scale with the needs of decentralized exchanges, Sei has made several optimizations to the Layer 1 to give exchanges the unfair advantage:

通过探索应用链和通用layer1之间的新设计空间，Sei 精心选择了一组独特的权衡，使其layer1成为 DeFi 应用的最佳环境。Sei 针对去中心化交易所的需求从下至上进行了扩展设计，对 Layer 1 进行了多项优化，使得其可为交易提供不可比拟的优势：

• 1.Native order matching engine - drives scalability of orderbook DEXs built on Sei 原生的订单匹配引擎 - 推动基于 Sei 构建的，订单簿类的DEX的可扩展性

• 2.Frontrunning protection - combats malicious frontrunning that is rampant in other ecosystems 抢跑保护 - 对抗在其他生态系统中猖獗的恶意抢跑

• 3.Intelligent block propagation - improves latency and throughput

  智能块传播 - 提高延迟和吞吐量

• 4.Sub-second settlement - Sei is the fastest chain to finality at ~600ms 亚秒级结算 - Sei 是达到最终态最快的链，大约 600 毫秒。

The combination of these optimizations make it possible for new types of financial products to emerge—everything ranging from live sports betting to complex options and futures.

这些优化的结合使新型金融产品的出现成为可能——从现场体育博彩到复杂的期权和期货，应有尽有。

Sei实验室团队 (The Sei Labs Team)

Sei实验室 is comprised of three types of backgrounds:

Sei实验室 由三类背景的成员组成：

• 1.Developers from Robinhood, Databricks, Airbnb, etc. with extensive expertise in orderbook design, infrastructure and the Cosmos stack 来自 Robinhood、Databricks、Airbnb 等的开发人员，在订单簿设计、基础设施和 Cosmos 技术栈方面拥有丰富的专业知识

• 2.Cosmos OGs who have navigated the ecosystem for years 多年来驾驭生态系统的Cosmos OG

• 3.Finance and strategy members from Goldman Sachs and other market makers who bridge the gaps between DeFi and institutions 来自高盛和其他做市商的财务和战略成员，他们弥合了 DeFi 和机构之间的差距
