Very greedy in electricity, is cryptocurrency mining, which consists of verifying the validity of transactions, a hyperpolluting activity and ultimately an ecological disaster?

While slayers and promoters of these decentralized technologies are tormented over this politically sensitive issue, the University of Cambridge is trying to bring factual and independent elements to the debate.
