Meni Rosenfeld is Founder of Bitcoil and Chairman of the Israeli Bitcoin Association. Having organized several meetups and conferences in Israel, he is a very active member of the Israeli Bitcoin community. Meni has been studying mining pool reward methods for several years and in 2011, wrote a paper titled “Analysis of Bitcoin Pooled Mining Reward Systems”. This research gave him a broad understanding the reward system landscape and the issues with many of the methods used by pools. He later wrote proposals for alternative non pay-per-share methods and which would render pool hopping impossible: the geometric method and double geometric method.
