What is the difference between Ethereum and mantle?

Could you kindly explain the fundamental differences between Ethereum and Mantle to me? I've been hearing a lot about these two platforms in the cryptocurrency and finance world, but I'm still a bit hazy on their distinct features. Ethereum, I understand, is a blockchain-based platform that enables the development and deployment of smart contracts and decentralized applications. But what exactly is Mantle, and how does it differ from Ethereum? I'm particularly interested in their use cases, scalability, and potential impact on the future of finance. Your insights would be greatly appreciated.
