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.

Coinapult’s CEO Ira Miller and marketing specialist Freya Stevens join us for a discussion about their company and plans for the future. We particularly dove into their new Locks feature, which allows people to ‘lock’ the value of their bitcoins to other assets such as US Dollar, Euro or gold from directly within the Coinapult wallet. The goal is to remove one often-named barrier to mainstream adoption: volatility. We also talked about the amazing ‘Let the Bit Drop’ project, which involves sending bitcoin per SMS to every resident of a small Carribean island. A party in Q4 will launch the project and educational materials will be given to residents via government channels.
