What is Coreum used for?

So, I'm curious to know, can you elaborate on what exactly Coreum is used for? I've heard it mentioned in the context of blockchain and digital currencies, but I'm not entirely clear on its specific functions and applications. Is it a utility token? A governance token? Or is it used for something entirely different within the crypto ecosystem? I'm looking for a concise yet comprehensive explanation to help me better understand the role of Coreum in the world of cryptocurrency and finance.
