# Sei By [ASGart](https://paragraph.com/@asgart) ยท 2023-06-06 --- Sei: The Fastest and Most Secure Blockchain for Trading If you are looking for a blockchain platform that can handle high-speed and high-volume trading of digital assets, you might want to check out Sei. Sei is a layer-1 blockchain that claims to be the fastest and most secure in the industry, with unparalleled performance, scalability and user-centricity. In this post, we will explore what Sei is, how it works and why it is attracting attention from developers, investors and institutions. What is Sei? Sei is a layer-1 blockchain that is designed to enable mass adoption of digital assets across various sectors, such as decentralized finance (DeFi), non-fungible tokens (NFTs) and gaming. Sei aims to provide a powerful infrastructure for building and running modern applications that require speed, security and fairness. Sei was founded by Sam Kazemian, the co-founder of Everipedia and Frax Finance, and 0xMaki, the former general manager of SushiSwap. They are joined by a team of experienced engineers, researchers and entrepreneurs who have worked at companies like Google, Facebook, Microsoft, Coinbase and Binance. Sei is backed by some of the world's leading operators, investors and institutions, such as Bitget, Foresight Ventures, Axelar, Pyth Network, Sushi and Kargo. Sei has also launched a $50 million ecosystem and liquidity fund to support new DeFi applications on its platform[https://techcrunch.com/2022/09/28/crypto-trading-focused-blockchain-sei-launches-50m-ecosystem-fund/](https://techcrunch.com/2022/09/28/crypto-trading-focused-blockchain-sei-launches-50m-ecosystem-fund/). How does Sei work? Sei leverages a novel consensus mechanism called Twin-Turbo Consensus, which combines two types of consensus algorithms: Fast Byzantine Agreement (FBA) and Proof-of-Stake (PoS). FBA is a leaderless consensus protocol that allows nodes to reach agreement on transactions in parallel, without relying on a single point of failure. PoS is a stake-based consensus protocol that secures the network by rewarding honest validators and punishing malicious ones. By combining FBA and PoS, Sei achieves both speed and security. Sei can process transactions in 500 milliseconds with finality, which means that once a transaction is confirmed, it cannot be reversed or changed. Sei can also handle up to 20,000 orders per second, which is more than 1,000 times faster than Bitcoin and 1,000 times faster than Ethereum[https://www.sei.io/](https://www.sei.io/). Sei also offers several features that make it user-friendly and fair. Sei is fully open-source and interoperable with other blockchains through Axelar Network. Sei also offers native frontrunning protection, which prevents malicious actors from exploiting the order book and manipulating prices. Sei also supports multiple levels of transaction bundling, which allows users to group multiple transactions into one and save on fees. Why should you care about Sei? Sei is not just another blockchain platform. It is a game-changer for the crypto industry, especially for traders who demand speed, security and fairness. Sei offers a superior alternative to existing blockchains that suffer from scalability issues, high fees, latency and frontrunning. Sei also opens up new possibilities for innovation and adoption of digital assets across various sectors. With Sei's powerful infrastructure, developers can build and run applications that were previously impossible or impractical on other platforms. For example, Sei can enable real-time prediction markets, high-frequency trading, complex NFTs and immersive gaming experiences. Sei is already attracting attention from some of the most prominent projects in the crypto space, such as SushiSwap, Pyth Network and Kargo. These projects are building on Sei to leverage its speed, security and user-centricity. Sei also has a vibrant community of supporters who believe in its vision and potential.
