Is Gala based on Ethereum?

Could you please elaborate on the relationship between Gala and Ethereum? I'm curious to know if Gala is indeed based on the Ethereum blockchain. If so, how does this foundation impact the functionality and operation of Gala? Also, what are the potential advantages or disadvantages of being built on Ethereum? Could you provide some insights into the technical aspects of this relationship, and perhaps explain how it differs from other cryptocurrencies that might not be based on Ethereum? Thank you for your time and assistance in clarifying this matter.
