Is ZEC decentralized?

As a keen observer of the cryptocurrency landscape, I'm curious about the underlying structure and principles of various coins. One coin that has piqued my interest is Zcash, often referred to as ZEC. Given its emphasis on privacy and anonymity, I'm wondering: Is ZEC truly decentralized? What mechanisms does it employ to ensure that power is not concentrated in the hands of a few? Does it adhere to the principles of decentralization as outlined in the original Bitcoin whitepaper? Or does it have some centralizing factors that may compromise its overall decentralized nature? Clarifying these points would help me better understand the true nature of ZEC and its position in the cryptocurrency ecosystem.
