EB49 – Meni Rosenfeld: Mining Pool Reward Systems, Bitcoin Economics, Bitcoin in Israel

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.
