What is the difference between conflux core and conflux eSpace?

Could you elaborate on the key differences between Conflux Core and Conflux eSpace? As I understand, both platforms are part of the Conflux ecosystem, but I'm not quite clear on their distinct functionalities and roles. Is Conflux Core the underlying infrastructure that powers the network, while Conflux eSpace is a decentralized application platform or some kind of user-friendly interface? Additionally, what advantages do each platform offer for developers and users within the Conflux network? Thank you for clarifying these distinctions.
