What is Sei?

Sei is a Layer 1 blockchain that is designed to optimize the decentralized finance (DeFi) ecosystem by providing a specialized, high-performance environment for trading and liquidity operations. It positions itself as an “order-book” blockchain, meaning it focuses on supporting exchanges, particularly those relying on order books rather than traditional automated market makers (AMMs). By focusing on enhancing scalability and improving the trading infrastructure for DeFi protocols, Sei seeks to become the backbone of the emerging financial systems in the decentralized space.

In the DeFi world, where speed, liquidity, and efficiency are paramount, Sei addresses many existing challenges in blockchain networks, such as latency issues, network congestion, and high transaction costs. Sei’s goal is to enable decentralized exchanges (DEXs) and other DeFi projects to operate with the efficiency and speed of centralized platforms, without compromising on security and transparency.

How Sei Works

At its core, Sei operates as a Layer 1 blockchain designed for high-throughput and low-latency operations. Unlike general-purpose blockchains like Ethereum, Sei is application-specific and optimizes its functionality around a particular use case: on-chain trading.

Here are key elements of Sei’s architecture:

1. Optimized for Order Book-based Exchanges:Unlike Automated Market Makers (AMMs), which use liquidity pools to facilitate trades, order books directly match buyers and sellers, creating a more efficient trading mechanism for certain types of assets. Sei has built an infrastructure designed to reduce slippage, enhance price discovery, and allow for advanced trading strategies.

2. Parallelized Processing:One of Sei’s major innovations is parallelized processing, which allows multiple transactions to be processed simultaneously. This ensures that high volumes of trades can be executed with minimal delays, even during periods of network congestion.

3. Native Price Oracles:Price oracles are crucial in DeFi for providing reliable external data to smart contracts. Sei integrates native oracles into its blockchain, ensuring that DeFi protocols built on its platform have direct access to real-time, trustworthy price feeds.

4. Front-running Prevention:Front-running is a major issue in DeFi trading, where certain actors gain an unfair advantage by executing their transactions just before larger orders are processed. Sei combats this problem through frequent batch auctioning, ensuring that all trades within a block are treated equally, preventing malicious actors from manipulating transaction ordering.

A Brief History of Sei

Sei emerged from the desire to create a blockchain that could cater specifically to the needs of decentralized finance applications, focusing on areas where existing blockchains struggled—speed, efficiency, and reliability for high-frequency trading.

1. Founding and Vision:The development of Sei began in 2021, spearheaded by a team of blockchain engineers and financial experts who recognized that the DeFi space was rapidly expanding but faced significant bottlenecks due to inefficient blockchains. The project’s goal was to create a blockchain that could seamlessly integrate with DEXs while maintaining a user experience comparable to centralized exchanges.

2. Initial Developments:Sei’s early stages focused on protocol development and creating partnerships with decentralized exchanges, projects in the DeFi space, and financial institutions interested in exploring blockchain technology. The focus on order book mechanisms differentiated Sei from many DeFi ecosystems built around AMM models.

3. Launch and Growth:Sei launched its mainnet in mid-2023 after several successful testnet phases where it demonstrated impressive throughput and efficiency gains over other blockchains. By focusing on niche yet crucial functionalities like high-frequency trading and real-time price feeds, Sei attracted a variety of DeFi projects to its ecosystem. Since its launch, Sei has continued to grow and is now regarded as a potential key player in the next wave of DeFi innovation.

Distinctive Features of Sei

Sei stands out in the blockchain ecosystem because of its tailored approach to solving DeFi-specific issues. Its architecture is not just focused on creating a general-purpose blockchain but rather aims to be a specialized Layer 1 for the DeFi space. Key features that set Sei apart include:

• Order-book Optimization:Sei’s infrastructure supports efficient order matching, a crucial aspect for traders in DEX environments. This feature allows for more advanced trading functionalities like limit orders, which are harder to implement on AMM-based systems.

• Parallelized Transactions:To combat latency and ensure faster transaction finality, Sei processes transactions in parallel, meaning multiple trades can be settled simultaneously without congestion, even in high-volume scenarios.

• Prevention of Front-Running:By using techniques like frequent batch auctions, Sei ensures fair transaction ordering, which protects traders from losing profits to front-runners.

• Native Oracles:Sei includes built-in price oracles, which provide secure, reliable data feeds directly into its ecosystem. This significantly reduces the dependency on external oracle providers and improves the reliability of DeFi applications operating on the platform.

• Composability:Like many other DeFi platforms, Sei emphasizes composability, allowing developers to build upon existing protocols and seamlessly integrate their applications within the broader DeFi ecosystem.

Governance on Sei

Sei’s governance model follows the typical DeFi principles of decentralized decision-making. Governance tokens are distributed to users, validators, and developers, giving them a voice in shaping the protocol’s future. These token holders can participate in voting on protocol upgrades, economic parameters, and other important decisions that affect the network.

The governance framework ensures that Sei remains a community-driven project, with its users playing a crucial role in maintaining and evolving the platform.
