Sui is a high performance smart contract platform under the Monolithic structure. In particular, Monolithic blockchain is a blockchain that handles all tasks and jobs on a single network. Sui is scalable up to several hundred thousand TPS (number of transactions processed per second) and block times range from 2 - 3s.

Sui's scaling is not the same as Solana or Internet Computer (spanning vertically) but somewhat similar to Ethereum 2.0's approach (horizontal expansion). Sui's goal is to expand Web3's ecosystem, providing an infrastructure with the right incentives for developers to quickly build and launch applications.
