Is Sui decentralized?

Excuse me, but could you clarify whether SUI is a decentralized platform or not? I'm curious to know if it operates in a manner that distributes power and decision-making across a network of nodes, rather than being controlled by a single entity or central authority. Understanding Sui's decentralization status is crucial for evaluating its potential in the cryptocurrency and finance space. Could you please elaborate on this aspect of Sui's architecture and operations?
