Is Trias on Ethereum?

Excuse me, I'm a bit confused about the relationship between Trias and Ethereum. Could you please clarify if Trias is built on the Ethereum blockchain or is it an independent blockchain project? I'm particularly interested in understanding the underlying technology and infrastructure that Trias utilizes. Also, if Trias is not on Ethereum, what are the key differences between the two platforms in terms of their functionality, scalability, and security? I'd appreciate any insights you can provide to help me better understand the landscape of blockchain projects.
