What is Cosmos doing?

I'm curious to know, what is Cosmos actually doing? It seems to be making waves in the cryptosphere, but I'm not quite sure what its core purpose and functionality are. Could you please explain in simple terms what Cosmos aims to achieve and how it's trying to revolutionize the world of finance and blockchain technology? Is it just another platform for trading cryptocurrencies, or does it offer something unique and innovative that could potentially change the game?
