What is SEI, and How To Buy It?

Sei is a Cosmos-powered, Layer-1 blockchain designed to simplify the work of decentralized exchanges (DEXs) and align their functionality with that of centralized exchanges (CEXs). It claims to achieve 390 ms block finality, which could make it suitable for high-frequency trading and real-time transactions. 

Another goal of this network is to enhance scalability and developer flexibility. It supports the creation of non-fungible tokens (NFTs) and play-to-earn games. 

SEI is the native cryptocurrency of the Sei blockchain, and allows participants to cover network fees when conducting transactions. It also plays a role in staking to bolster security, and provides participants with governing rights within the network. Crypto aficionados can track the value of SEI, including other crypto prices, on CEX.IO.
