What network is Jito on?

Could you please clarify for me which network Jito operates on? I'm quite curious to understand the technological backbone that supports this platform. Is it built on a well-known blockchain, or perhaps a newer, more innovative network? I'm interested in its scalability, security features, and transaction speeds. Could you provide some insight into the network infrastructure that Jito leverages? Thank you in advance for shedding light on this matter.
