What is Sui doing?

I'm curious to know, could you elaborate on what Sui is currently working on? Are they developing a new blockchain protocol or focusing on a specific application for their technology? What are their key objectives and milestones for the NEAR future? Additionally, are there any partnerships or collaborations that Sui has recently announced or is in the process of forging? I'm particularly interested in understanding the direction Sui is heading in and how they plan to differentiate themselves in the crowded cryptocurrency and blockchain space.
