What is a BigONE?

Could you please explain to me what exactly a BigONE is in the world of cryptocurrency and finance? I've heard it mentioned in various forums and discussions, but I'm still unclear on its specific function and purpose. Is it a cryptocurrency exchange? A blockchain-based platform? Or something else entirely? I'm eager to learn more about this seemingly influential entity and how it fits into the broader landscape of digital assets and decentralized finance.
