What chain is Coti on?

Excuse me, could you please elaborate on the blockchain technology that Coti utilizes? As a cryptocurrency enthusiast, I'm curious to understand the underlying infrastructure that powers this platform. I've heard about various blockchains, each with its unique features and advantages. So, I'm particularly interested in knowing if Coti is built on a popular, well-established chain like Ethereum, or if it's leveraging a newer, more innovative solution. Any information you could provide would be greatly appreciated.
