What network is Velodrome on?

Excuse me, I've been hearing a lot about this new cryptocurrency project called Velodrome lately, but I'm not entirely sure about its technical details. Could you please enlighten me on what network Velodrome is actually built on? I'm curious to know if it's a fork of an existing blockchain, or if it's a completely new and innovative platform. Understanding the underlying network is crucial for me to assess its potential and viability in the long run. Thank you for your time and assistance in clarifying this matter.
