dMark | digital Mark | Efficient mass-market cryptocurrency | Practical cryptomoney - The digital Mark (dMark, dM, DIM) has the superordinate objective to establish a mass-market cryptocurrency. - To achieve this there are three major design objectives: usability for laymen, energy sustainability, removal of capacity limits. - A central register - digitalEnergyRegister / dEnReg - will be introduced which will tag users with energy classes. There may be the possibility to open this up for other applications in the long run. - Users will be rewarded if they utilize renewables. A "green cryptocurrency" will be created. - The dMark will reuse proven designs and implementations, where possible. And introduce improvements/modifications, where necessary.
