What is Holo network?

Can you please elaborate on what exactly the Holo network is? I've heard of it being referred to as a decentralized hosting platform, but I'm curious about its specific functions and how it differs from other blockchain-based projects. Is it focused on a particular use case or does it aim to provide a versatile solution for various applications? I'm also interested in learning about the technology behind it and how it aims to improve upon existing systems in the field of cryptocurrency and finance.
