**What is Sei?**

Sei is the first sector-specific Layer 1 blockchain, specialized for trading. Every aspect of the blockchain has been optimized to help exchanges run better and offer the best UX for their end users.

1.Native order matching engine - drives scalability of orderbook DEXs built on Sei

2.Breaking Tendermint - Sei is the fastest chain to finality at ~600ms

3.Twin-turbo consensus - improves latency and throughput

4.Frontrunning protection - combats malicious frontrunning that is rampant in other ecosystems

5.Market-based parallelization - specialized parallelization for DeFi

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.

### What makes Sei a unique Layer 1?

General purpose advantages:

1.Atomic composability - all apps are built on 1 blockchain so can easily work with each other

2.Social coordination - the ultimate unlock. single core community with a single schelling point

App-specific advantages:

1.Customizability - if you're building a chain around a single app, you can change things up

2.Native, multi-chain interoperability - the power of IBC

Sei **combines** the advantages of general purpose Layer 1's with those of app specific chains.

**How exactly is Sei the optimal Layer 1 for exchanges?**

### Technical Breakthroughs

*   **Twin-Turbo Consensus:** intelligent block propagation + optimistic block processing
    
*   **Native order matching engine**: driving scalability for orderbook DEXs on Sei
    
*   **Breaking Tendermint:** Sei is the fastest chain to finality at 600ms
    
*   **DeFi-specific parallelization:** massively increases throughput and order processing
    

### Frontrunning Prevention

*   By redesigning Sei from top to bottom, there have been major improvements in transaction processing and the mempool to help combat frontrunning
    
*   **Frequent batch auctioning**: rather than executing each order one-by-one (as would happen on Ethereum or Solana). Sei can aggregate every order together at the end of the block and execute all market orders at the same price to help prevent frontrunning
    
    **Come explore the DeFi design space!**
    
    The Sei mission is to build infrastructure for the future financial system to support capital markets, starting with exchanges.
    
    Sei offers grants and access to an ecosystem of venture capital firms for strong teams. If you are interested in building on Sei:
