Is Terra Luna built on Cosmos?

I'm curious, is Terra Luna indeed constructed upon the Cosmos ecosystem? I've heard rumors about this, but I'd like to have a clearer understanding. Could you elaborate on the technological foundation of Terra Luna and its relationship with Cosmos? Does it leverage any specific features or functionalities of Cosmos? Also, what are the potential advantages or limitations of building on Cosmos, in comparison to other blockchain platforms? Your insights would be greatly appreciated.
