Sui is considered a next-generation blockchain because it pushes beyond the limits of traditional designs by using parallel execution to process many transactions at once, while still delivering fast finality so users don’t wait long for confirmations. Its object-centric model makes it easier for developers to build flexible applications, and the network is designed with user experience in mind so that Web3 apps can feel as smooth and responsive as Web2 platforms. This mix of speed, scalability, and usability is what sets it apart.
