What network is Telos on?

Excuse me, could you elaborate on the network infrastructure that Telos is utilizing? I'm curious to understand the technological backbone that supports this cryptocurrency and its transactions. Is it built on a pre-existing blockchain, or is it a unique, proprietary system? Furthermore, how does its network architecture compare to other established cryptocurrency platforms, in terms of scalability, speed, and overall performance? Clarifying this aspect of Telos' operation would greatly assist in evaluating its potential and market position.
