Who is the owner of DeFi chain?

Could you clarify who the owner of DeFi chain is? I understand that DeFi, or decentralized finance, refers to financial services that operate on blockchain technology without the need for intermediaries, but I'm unsure about the specific ownership structure of the DeFi chain itself. Is it a decentralized network without a single owner, or is there a specific entity or group that holds the ultimate authority over it? Your insight into this matter would be greatly appreciated.
