Is Arweave on the Ethereum network?

I'm quite curious about the relationship between Arweave and Ethereum. Could you clarify for me if Arweave operates on the Ethereum network? I've heard some rumors that it might, but I'd like to have a definitive answer from a professional like you. Given that Ethereum is such a popular and established blockchain platform, it would make sense if Arweave was built on it. However, I also understand that each project has its unique technology and infrastructure. So, is Arweave indeed a part of the Ethereum ecosystem, or does it operate independently? I'd appreciate your insights on this matter.
