Is DOGE decentralized?

Could you clarify whether DOGE is truly decentralized? I've been hearing a lot of buzz about it, but I'm still not quite sure about its underlying structure. Is it built on a distributed ledger system like Bitcoin? Or does it rely on centralized authorities to maintain its operations? I'm particularly interested in understanding how its governance and decision-making processes work. Is there a community consensus mechanism involved? And what role does the DOGE foundation or team play in its governance? Could you please elaborate on these points?
