Is Nexo centralized or decentralized?

Could you please elaborate on whether Nexo operates as a centralized or decentralized platform? I'm interested in understanding the structure and organization of its operations. Could you provide insights into its architecture, governance, and decision-making processes? Additionally, I'm curious about the security measures it employs to protect user funds and transactions. How does Nexo ensure transparency and trustworthiness in its operations? Is there a way to verify the authenticity and integrity of its services? Lastly, how does Nexo compare to other similar platforms in terms of centralization or decentralization?
