Bitcoin and other cryptocurrencies use blockchain technology, essentially a shared database of transactions, where entries must be confirmed and encrypted. The network is secured by “miners” who use powerful computers to compete in an enormous guessing game that ultimately verifies the transactions. If a computer “wins” the game, it’s rewarded with a newly created bitcoin, currently worth about $40,000. The process consumes a lot of electricity, and the computers generate a lot of heat, which means they require industrial cooling systems that need even more energy. | |||
