Ethereum is closer than it ’s ever been to chuck its highlyenergy intensiveproof - of - work model for a proof - of - stake ( POS ) choice .
This hebdomad , Ethereum course its net test of the new POS scheme before it ’s set toofficially transitionnext month . The move , once completed , could mark a seismal shift for the crypto industry which has continually had to brush off justified claims , include somemade on this web site , that cryptocurrencies are an inherent strain on the environment .
The test , first reportedon by CNBC , is one of the last checkmarks on the to - do list before the so - called “ Merge ” takes effect .

As a quick refresher , POS advocates , climate research worker and others have push Ethereum to transition away from prisoner of war due to its heavy trust on Energy Department for minelaying . Though there was a fourth dimension when Bitcoin and Ethereum drug user could simply mine the currencies using the computers in their bedroom , that clip has long pass . Now , Bitcoinreportedlyrequires over 200 terawatts of power per year to solve the complex math problems necessary to mine currency and verify transactions . That’sequivalentto the energy consumption of many modest nation .
POS , on the other hand , should theoretically dramatically reduce energy wasting disease by using other Ethereum user ’s machines to verify block on the blockchain . As Investopediaputs it , Ethereum owners “ offer their coins as collateral ” to validate pulley-block . These so - call “ validators ” are then randomly take to reassert that each dealing made on the blockchain is true . The result here , according tosupporters of the Merge , is that trial impression - of - stake excavation will use 99 % less Energy Department consumption than proof - of - body of work modeling .
During this week ’s tests , CNBC note , Ethereum ’s Goerli test meshwork conducted a pretense mimicking what will pass off when the merge occurs next calendar month . Though the test was n’t without some singultus , multiplecryptocurrencyresearchers , including Ansgar Dietrichs of The Ethereum Foundation described the event a “ successful test . ” Ether , the coin attached to Ethereum , break up its economic value by 11 % on Thursday follow the testsaccording toMarkets Insider .

The POS switch has been in the works for several years ( Ethereum co - founder Vitalik Buterinwroteabout the mind as too soon as 2013 ) , but only recently receive a hard dateearlier this twelvemonth . That escort , though still somewhat tentative , is Sept. 19 .

If all buy the farm according to architectural plan and Ethereum ’s succeeder switches to POS on that date , the environmental issues surrounding cryptocurrency wo n’t suddenly unthaw away . Bitcoin , the leading cryptocurrency , still relies on POW , something that ’s not likely to change , and countless other smaller proof - of - work coins also exist . That say , Ethereum ’s the secondly largest blockchain so an energy economic consumption step-down that comes even close to what POS advocates would mark an important , consequential shift .
