TLDR

Sei is a Layer 1 blockchain built to support fast, low cost financial applications, especially trading and decentralized finance.

  1. Its design aims to process independent transactions in parallel, reducing delays when the network is busy.

  2. It supports Ethereum compatible applications, while SEI is used for transaction fees, staking, and governance.

Deep Dive

1. Purpose and technology

Sei is a blockchain where developers can build applications and users can transact without relying on a central operator. It focuses on financial apps, where quick transaction processing can be useful.

Its parallel execution design lets the network process transactions that do not affect one another at the same time. Sei also supports the Ethereum Virtual Machine (EVM), the software environment used by Ethereum apps, so developers can use familiar tools. These design goals are described in Sei’s overview and project documentation.

2. SEI token

SEI is the network’s native token. Users pay transaction fees in it, and holders can stake it, meaning they delegate tokens to help validators secure the network. SEI holders can also participate in on chain governance, or voting on network proposals. (Token overview)

Conclusion

Sei is a blockchain focused on fast financial applications, with an Ethereum compatible environment and SEI supporting fees, staking, and governance. How effectively will its parallel processing help real applications work smoothly as network activity grows?
