Cryptocurrencies have made their mark in the financial sector by providing distributed systems that ensure people and corporations once again regain control of themselves. However, there’s also a catch behind this technological shift; usual cryptocurrencies such as Bitcoin depend upon power-intensive transaction verification processes.
Yet, bitcoin mining alone is estimated to use as much electricity in a year as some small nations. Much of this enormous energy need typically comes from non-renewable energy sources, resulting in greater carbon emissions and fueling the already burning climate emergency.
That’s where green cryptocurrencies seek to reduce energy usage, utilize eco-friendly technology, and even offset their impact with carbon-neutral endeavors.
