Ethereum prepares its great "green" transformation

This is one of the major projects to come in the world of cryptocurrencies. This summer, the Ethereum blockchain, which is the 2nd largest in terms of capitalisation ($238 billion), will migrate to a system that is supposed to be much more energy-efficient, as its founder, Vitálik Buterin, announced a few days ago. It's a move that comes just at the right time, as criticism of the environmental impact of cryptocurrencies continues to mount.
