Proof of Entropy Minima (PoEM) is a consensus algorithm that is used by the Gridcoin cryptocurrency. PoEM is a unique consensus algorithm that aims to incentivize scientific research and distributed computing. In PoEM, nodes in the Gridcoin network compete to solve scientific problems and generate useful results, which are then used as a measure of computational power. The more scientific problems a node solves, the more computational power it has, and the more likely it is to be chosen as th...
