What is Mev Jito?

Could you please explain to me what Mev Jito actually is? I've heard the term mentioned in the cryptocurrency community but I'm not quite sure what it entails. Is it a specific type of transaction, a protocol, or perhaps a service? How does it work, and why is it considered significant in the finance world? Could you also elaborate on any potential risks or benefits associated with Mev Jito? Thank you for your assistance in clarifying this matter.
