What is SEI: Understanding the Software Engineering Institute and Its Impact on Modern Technology

Sei's Positioning and Significance

In 2023, the Sei team launched Sei (SEI), aiming to solve the exchange scalability problem in the cryptocurrency market.

As the first Layer 1 blockchain dedicated to transactions, Sei plays a crucial role in digital asset exchange, including game assets, social networking, and NFTs.

As of 2025, Sei has become a top 100 cryptocurrency by market cap, with a market capitalization of $1,026,692,444 and an active developer community. This article will analyze its technical architecture, market performance, and future potential in depth.

Origin and Development History

Background of Creation

Sei was created by the Sei team in 2023, aiming to address the inefficiency and scalability issues in digital asset exchanges.

It was born during the rapid development of blockchain technology and the increasing demand for efficient digital asset trading platforms, with the goal of providing a high-performance infrastructure for digital asset exchanges to change the status quo.

Sei's launch brought new possibilities for cryptocurrency traders and decentralized applications.

Important Milestones

• 2023: Mainnet launch, achieving high transaction throughput and optimized performance for exchanges.
• 2024: Major upgrade introducing enhanced features for digital asset trading and improved scalability.
• 2025: Adopted by various decentralized applications, pushing the price to its all-time high of $1.14463.
• 2025: Ecosystem expansion, with the number of DeFi protocols and NFT platforms built on Sei growing significantly.

With support from its community and development team, Sei continues to optimize its technology, security, and real-world applications.

How Does Sei Work?

Decentralized Control

Sei runs on a decentralized network of computers (nodes) spread across the globe, free from control by banks or governments. These nodes collaborate to validate transactions, ensuring system transparency and attack resistance, giving users greater autonomy and improving network resilience.

Blockchain Core

Sei's blockchain is a public, immutable digital ledger that records every transaction. Transactions are grouped into blocks and linked through cryptographic hashes to form a secure chain. Anyone can view the records, establishing trust without intermediaries. Sei's unique optimized architecture for exchanges further enhances performance.

Ensuring Fairness

Sei uses a Proof-of-Stake (PoS) consensus mechanism to validate transactions and prevent fraudulent behaviors like double-spending. Validators maintain network security by staking SEI tokens and validating transactions, and receive SEI rewards in return. Its innovations include high transaction throughput and low latency, specifically optimized for exchange operations.

Secure Transactions

Sei uses public-private key cryptography to protect transactions:

• Private keys (like secret passwords) are used to sign transactions
• Public keys (like account numbers) are used to verify ownership

This mechanism ensures fund security, while transactions remain pseudonymous. Sei also implements additional security features optimized for exchange operations.
