How does SSV work?

Could you elaborate on the workings of SSV, please? I'm particularly interested in understanding how it functions within the cryptocurrency and finance landscape. I'd like to know if it's a decentralized protocol, how it secures its network, and how investors or users can interact with it. Additionally, I'm curious about its underlying technology, potential use cases, and any unique features that set it apart from other similar projects. Your insights would be greatly appreciated.
