What is the old name of OKX?

Could you possibly clarify for me something? I've been hearing a lot about OKX in the cryptocurrency circles, but I'm a bit out of the loop on its history. Could you tell me what the old name of OKX was? I'm really curious to learn more about its origins and how it has evolved over time. It seems to be quite a popular platform nowadays, so I'm eager to understand its journey from its inception to its current status. Any insights you could provide would be greatly appreciated!
