How decentralized is flow?

Could you please elaborate on the decentralization level of Flow? I'm interested in understanding how distributed its network architecture is, how many nodes it comprises, and how secure its consensus mechanisms are. Additionally, how does its decentralization compare to other major blockchain platforms? Is there any centralized aspect in its operations that might pose a threat to its decentralization? I'm keen to gain a deeper understanding of this aspect as it's crucial for assessing the overall trustworthiness and resilience of the Flow blockchain.
