What is the DeFi halal protocol?

Could you please explain what the DeFi halal protocol actually is? I'm interested in understanding its core principles and functionalities. Could you also elaborate on how it differs from traditional financial systems? Additionally, I'd like to know about its potential benefits and any challenges it might face in the current crypto landscape. Is it suitable for retail investors, and how does it ensure compliance with halal finance regulations? I'm keen to learn more about this emerging trend in the cryptocurrency and finance industry.
