TECHEthereum’s massive software upgrade just went live — here’s what it does

$Ethereum(ETH.CC)$ ’s biggest-ever upgrade just took effect, in what industry experts are calling a game changer for the entire crypto sector.
Thus far, all signs suggest the so-called merge — which is designed to cut the cryptocurrency’s energy consumption by more than 99% — was a success.
Ether surged more than fivefold in 2021, outperforming $Bitcoin(BTC.CC)$ by a wide margin, in part on optimism over the Merge. Both tokens have struggled since hitting record highs in November, with Ether down more than 50% this year.
