Could you elaborate on the Cetus protocol? I've heard it mentioned in the context of
cryptocurrency and finance, but I'm not entirely clear on its functionality and significance. Specifically, I'm interested in understanding how it works, what problems it aims to solve, and how it differs from other protocols in the same field. Additionally, I'd appreciate any insights you have on its potential impact on the cryptocurrency ecosystem and the broader financial landscape. Could you provide a concise yet comprehensive description of the Cetus protocol?
