Electroneum’s ETN has once again gone to where no other cryptocurrency in the industry has gone to become the eco-friendliest in the crypto space. The company has launched a software update with game-changing features leading to the transformation of the cryptocurrency industry by reducing its carbon footprint drastically. Proof of Responsibility drastically reduces the electricity required to mine ETN from the equivalent of lighting approximately 2.4 million light bulbs to about on light bulb a day. Bitcoin, for example, has a carbon footprint equal to that of Las Vegas, according to scientists.
