What is cortex CTXC?

Could you please explain to me in simple terms what Cortex (CTXC) is? I've heard it mentioned in the context of blockchain and cryptocurrency, but I'm not entirely sure what its purpose or functionality is. Is it a coin or a token? What kind of problems does it aim to solve? And how does it differ from other cryptocurrencies in the market? I'm really interested in learning more about it.
