Sei is an L1 blockchain that supports transactions and dApps. More importantly, it wants to combine Ethereum EVM, as in development environment, and Solana's ability to handle transactions quickly.
Sei wants to boast the throughput of a blockchain, with a 390-millisecond time to finality, and the ability to handle over 12,500 transactions per second.
Sei also fully integrates Ethereum-based apps, which makes Sei one of the best blockchains when it comes to interoperability.
Sei also came up with a database system that can handle transaction volumes extremely rapidly, they call it the SeiDB, and a consensus that they call Twin Turbo Consensus.
If you can get over the funny name, the consensus is what allows Sei to finalise a transaction in 390 milliseconds.
Sei also wants to improve the overall speed required to make a transaction irreversible, in a single block.
They have a name for that, too. They call it the 'Single slot finality'.
Sei's ecosystem includes NFTs, GameFi, ie gaming finance, and DeFi, with the Sei token being at the centre of the action for both operations and governance.
Staking is available, by the way.
The goal is to keep the network scalable, but also efficient, but also reliable, and also robust.
Do you hold any Sei?
I used to, for a while, but then I sold everything.
