Another term for PoW is “mining”, as it is essential for the generation and in turn circulation of new coins. Bitcoin mining is done with Proof-of-Work. How can Crypto Reduce its Carbon Footprint? Fueling crypto mining with renewable energy resources instead of fossil fuels can be one step towards decarbonization. Another method that is being considered by various blockchains such as Ethereum, is shifting their mining process from Proof-...
