How does mask network work?

Could you please elaborate on the workings of Mask Network in a concise manner? I'm curious to understand how it functions and its key components. Specifically, how does Mask Network enable privacy-preserving interactions on blockchain-based applications? What are the core technologies or mechanisms it employs to achieve this? And how does it integrate with existing blockchains and decentralized applications? Any insights into its architecture or user experience would be greatly appreciated.
