Bitcoin’s huge energy waste

It’s thanks to “blockchains” that cryptocurrencies can be created without a central supervisory authority. The bitcoin is one of these currencies, but it works based on “miners” who compete in computations. The result is energy consumption that’s both huge and unnecessary, according to Jean-Paul Delahaye, professor emeritus at University de Lille and CRISTAL researcher at the French National Centre for Scientific Research (CNRS). It’s what he calls “Nakamoto’s blunder.”
