How to Do DeFi in 20 Years The fairest airdrop I have ever seen is a Taiwanese project called Hakka. Ten extremely difficult partial differential equation problems have been solved because the mathematical principles behind this project are based on this. The first one to solve and submit the correct answer will receive an airdrop Old fans know that I have a friend who went crazy later Li Xiaohu, a popular mathematics PhD from the Chinese Academy of Sciences I solved half of the final question with him alone. He didn't have any knowledge of blockchain and didn't understand the question, so I solved it first But this set doesn't work anymore. There's no doctor left AI solves problems quickly. Compared to that era. The blockchain of this era is purely a play of grass and grass.
