Is Terra based on Cosmos?

Terra, is it indeed founded upon the Cosmos blockchain technology? I've heard rumors that it utilizes some of the fundamental principles and functionalities inherent in Cosmos's ecosystem. Could you clarify this for me? It seems like an intricate yet fascinating connection, if indeed true. I'm particularly interested in understanding how Terra might leverage Cosmos's interoperability features, if any, to enhance its own functionality and ecosystem. Would you be able to elaborate on this point, and perhaps provide some insights into the technical aspects of this supposed relationship?
