BEGINNER: OVERVIEW OF SEI

: What is SEI

The Sei Network is a layer-1 blockchain, specifically optimized for trading applications. It is built to provide a highly scalable, low-latency, and decentralized infrastructure, tailored to meet the demands of decentralized exchanges (DEXs), trading platforms, and DeFi (Decentralized Finance) applications. Sei leverages the Cosmos SDK, allowing it to integrate into the wider Cosmos ecosystem, supporting interoperability through IBC (Inter-Blockchain Communication) with other chains. Sei’s focus on trading ecosystems makes it unique in the crypto landscape, with specialized consensus algorithms, parallelization, and an efficient order-matching engine designed to optimize throughput and execution speed.

Vision

Sei Network aims to be the backbone of decentralized finance by becoming the go-to infrastructure for all trading applications. The vision revolves around creating a highly liquid, transparent, and efficient trading experience for both retail and institutional users. By addressing issues related to slow execution times, front-running, and liquidity fragmentation, Sei envisions a blockchain where decentralized exchanges can operate at speeds comparable to centralized counterparts, with lower costs and enhanced security.

Sei also seeks to bring traditional financial markets onto blockchain technology, offering a gateway for non-crypto markets to enter the decentralized world, providing the necessary infrastructure to bridge the gap between TradFi (Traditional Finance) and DeFi.

Mission

Sei’s mission is to empower builders, traders, and developers by providing a high-performance, scalable blockchain that solves core inefficiencies in the trading space. By offering fast execution, low latency, and deep liquidity, Sei Network aims to be the go-to platform for building financial applications.

Sei is committed to decentralization, scalability, and accessibility, ensuring that its infrastructure not only scales with demand but also remains secure and developer-friendly. Sei Network also focuses on empowering the broader crypto ecosystem by offering tools, incentives, and frameworks that simplify onboarding for developers, creators, and users from various sectors, including DeFi, NFTs, and gaming.

Key Features and Advantages

I) Optimized for Trading:

Sei’s primary differentiation comes from its focus on trading, offering custom-built infrastructure to support high-speed decentralized exchanges. It features a central limit order book (CLOB), making it easier for DeFi projects to integrate efficient trading capabilities.

Ii) Sei’s innovative Twin Turbo consensus is designed to maximize throughput and minimize latency, achieving low finality times, typically around 300 ms. This efficiency makes the network a preferred choice for applications requiring quick execution and settlement.

lII) Native Frontrunning Protection:

Frontrunning, a major problem in decentralized exchanges, is mitigated through Sei's native solutions. The network implements intelligent block propagation techniques and fair sequencing to ensure a more equitable trading environment.

lV) Interoperability:

Being built with the Cosmos SDK, Sei is naturally interoperable with other Cosmos-based chains through the IBC. This means that assets and data can move seamlessly between Sei and other blockchains, offering cross-chain liquidity and a more integrated ecosystem.

V) Seamless Onboarding for Developers:

Sei is developer-friendly with robust documentation, APIs, and development tools that allow for easy deployment of dApps. It integrates EVM (Ethereum Virtual Machine) compatibility, making it easy for Ethereum-based applications to migrate or build on Sei.
