What is Polymesh used for?

Could you elaborate on the purpose and functionality of Polymesh? As a cryptocurrency enthusiast, I'm particularly interested in understanding how it differs from other blockchain platforms. Specifically, what kind of transactions or use cases does Polymesh cater to? I've heard it's tailored for regulated assets, but how does that translate into practical applications? Could you provide some examples of how Polymesh might be used in the financial industry, or any other sectors? Furthermore, how does its governance model contribute to its unique purpose? I'm eager to gain a deeper understanding of this promising blockchain technology.
