Sei is a general purpose layer-1 blockchain that is open soursed and optimized for trading; A common misconception is Sei is a DeFi chain, because most people don’t realize how universal trading is to gaming, social, NFTs. Trading is general purpose!
It is built on the Cosmos SDK and uses Tendermint consensus.
Sei's main features include:
Lightning-fast transaction finality: Sei uses a unique consensus mechanism called Twin-Turbo Consensus, which allows it to achieve transaction finality in just 600 milliseconds, with a lower bound of 300milliseconds. This is significantly faster than other blockchains, which can take several seconds or even minutes to finalize transactions, achieving industry-leading performance!
High throughput: Sei can process up to 22,000 orders per second. This makes it suitable for high-volume trading applications, such as decentralized exchanges (DEXs).
Built-in orderbook: Sei has a built-in orderbook that allows users to trade assets directly on the blockchain. This eliminates the need for centralized exchanges, which can be slow and expensive.
Interoperability: Sei is interoperable with other Cosmos-based blockchains, which allows for the cross-chain trading of assets. This is a major advantage for Sei, as it opens up the possibility of trading assets from different blockchains on a single platform.
Twin-Turbo Consensus: The Twin-Turbo Consensus mechanism is made up of two features: intelligent block propagation and optimistic block processing. Intelligent block propagation is a way of transmitting block proposals in a blockchain system that increases the efficiency of the disseminating blocks such that consensus and validation can occur more efficiently. Optimistic block processing is a way of processing blocks that assumes that the blocks are valid unless there is evidence to the contrary. This allows for faster block processing and finality.
Central Limit Order Book (CLOB): A CLOB is a type of order book that allows for efficient trading of large volumes of assets. It works by grouping together orders of similar size and price, which allows for more efficient matching of buyers and sellers.
Shared Liquidity Model: The shared liquidity model is a way of sharing liquidity between different markets on the same blockchain. This makes it easier for users to find the best prices for their trades, as they can choose the market with the most liquidity for the asset they want to trade.
CeFi-DeFi Hybrid: Sei blockchain combines the best of both CeFi and DeFi. This means that users can enjoy the convenience and user-friendliness of CeFi, while also benefiting from the security and transparency of DeFi. For example, SeiDEX, the decentralized exchange built on Sei blockchain, offers margin trading, which is a feature that is typically only available on centralized exchanges.
There are already 150+ teams building on Sei from Ethereum, Sui, zkSync, Polygon, and Solana.
I believe that Sei blockchain has the potential to be a major player in the blockchain space. It is fast, secure, and interoperable, and it has a number of features that make it attractive to traders and investors. I am excited to see how Sei blockchain develops in the future
