Is Aptos decentralized?

Could you please clarify whether Aptos is truly decentralized? It's an important factor to consider when evaluating a cryptocurrency or blockchain project. Decentralization typically refers to the distribution of power and control among various nodes or participants in a network, rather than being centralized under a single entity or authority. In the context of Aptos, I'm interested in understanding its architecture and governance mechanisms. Is it designed to ensure that no single party can unilaterally control or manipulate the network? Are there multiple independent validators or miners participating in the consensus process? Additionally, I'd like to know if Aptos has any built-in mechanisms to prevent centralization over time. For instance, are there measures to encourage participation from a diverse set of stakeholders and prevent the accumulation of too much power in the hands of a few? I believe that a thorough understanding of these aspects will help me evaluate the overall decentralization level of Aptos and its potential as a secure and robust blockchain platform. Thank you for your clarification.
