I'm definitely not the best person to explain it to you. It's all very new to me and most of it I don't understand. If you click on the Defi tag on the top of the page and scroll back you should be able to find some articles people wrote when it first started.

Or if you go on the CubDefi platform there is a document that explains it. It was all a bit complex for me though to be honest. The posts were better.

Sorry I can't help more. 
