After introducing Bybit's halal version of the exchange last time, Binance has just launched its halal version of wealth management, Sharia Earn. It seems that the global 2 billion Muslim users will become an important source of new customers for the exchange in the future. Previously, it was mentioned that the most unique aspect of Muslim doctrine is the absence of interest, as they consider it a form of capital exploitation, which means they cannot participate in the most extensive staking activities in the cryptocurrency community. This time, Binance's Sharia Earn allows Muslim users to participate in the staking of BNB, ETH, and SOL, and has been certified by Amanie Advisors, an Islamic law consulting company, to ensure that the entire process is halal and in compliance with the doctrine. However, there is currently no detailed explanation of how the staking rules can avoid the concept of "interest" while still earning profits. The key difference lies in the compliance model and underlying reward structure. In fact, Islamic finance has many clever ways to indirectly replace interest, such as changing to profit sharing, rent collection, and other models, which is a bit like a word game. I boldly speculate that the underlying logic implemented by Sharia Earn may be that users rent out their BNB, SOL, and ETH Give to Binance, then Binance will help with staking, and finally the user will receive "rent", which comes from the proceeds of Binance staking.
