Is STX decentralized?

Could you please elaborate on the decentralization aspect of STX? I'm curious to know if it truly embodies the principles of decentralization or if there are certain centralized elements involved. Could you also discuss the extent to which STX's decentralization affects its security, scalability, and overall functionality? Additionally, how does STX's decentralization compare to other cryptocurrencies in the market? It would be helpful to get a comparative analysis of its decentralized nature. Thank you for your insights!
