In the beginning of Crypto mining, it was well distributed among a couple of thousand private miners, governed by transparent rules and not harmful to the climate because its energy requirements were microscopic. All that has changed: the exponential growth of cryptocurrencies has led to a dramatic increase in the sector’s energy consumption and a concentration of mining activities in countries with low social and environmental standards - where electricity is produced using predominantly fossil fuels. Even worse, the concentration of mining power in the hands of a couple of large corporations is distorting the formerly democratic decision-making process in these networks: changes in protocols and hard forks are in danger of being influenced by the economic interests of a few. Nativecoin has developed a system of Mobile Mining Units (MMU’s) that can be powered directly using: Solar, Hydro, Wind and fossil power plants in every part of the World. Nativecoin MMU’s are based on standard intermodal (sea) containers, equipped with mining hardware, communication and industry 4.0 automation features, remote control capabilities and a break-through cooling system that only makes up ~1% of the system‘s total energy consumption.
