That is no mean feat, given that the Ethereum blockchain was burning through about as much electricity as New Zealand.
Sceptics had expected glitches with the upgrade, known as "the merge", but it ended up being a "rather boring event", according to Alex de Vries of the Free University in Amsterdam.
De Vries, whose Digiconomist website models the energy use of Bitcoin and Ethereum, said consumption had indeed plummeted by more than 99 percent on Ethereum.
Moritz Platt, a researcher specialising in crypto at King's College London, said the 99 percent estimates were realistic and heralded a positive step towards "cryptocurrency sustainability".
