Tsoomfwv Meskas Lub Tsev Pawg Saib Xyuas Hluav Taws Xob thiab Kev Lag Luam muaj tshaj tawm ib lub rooj sib hais txog kev lag luam cryptocurrency lub zog noj. Lub rooj sib hais yuav muaj rau hnub Thursday, Lub Ib Hlis 20, 2022.
"Nyob rau hauv ob peb xyoos luv luv, cryptocurrency tau pom ib qho kev nce siab hauv qhov muaj koob meej. Nws yog lub sijhawm los nkag siab thiab hais txog lub zog thiab kev cuam tshuam ib puag ncig uas nws muaj rau peb cov zej zog thiab peb lub ntiaj teb, "said Committee Thawj Tswj Hwm Frank Pallone (D-NJ) thiab Tus Thawj Saib Xyuas thiab Kev Tshawb Fawb Tus Thawj Coj Diana DeGette (D-CO) hauv ib nqe lus sib koom.
Ob leeg tau hais ntxiv tias qhov tseem ceeb ntawm lub rooj sib hais no yuav yog ntawm cov pov thawj ntawm kev ua haujlwm (PoW) blockchains-zoo li cov uas siv los ntawm Bitcoin thiab Ethereum-thiab yuav ua li cas xws li cryptocurrencies tuaj yeem hloov mus rau lwm txoj kev huv.
"Peb tos ntsoov rau kev tshuaj xyuas crypto mining qhov kev loj hlob ntawm lub zog hneev taw thiab yuav ua li cas cov ntaub ntawv pov thawj ntawm kev ua haujlwm blockchains, tshwj xeeb, tuaj yeem hloov mus rau cov kev hloov huv huv thiab cov kev daws teeb meem txuas ntxiv dua tshiab."

Cryptocurrency thiab ib puag ncig
Kev cuam tshuam ib puag ncig ntawm PoW blockchains yog lawm sau tau zoo-ntawv.
Cov ntaub ntawv pov thawj-ntawm-ua haujlwm blockchains yuav tsum muaj cov khoos phis tawj muaj zog los ua cov lej lej nyuaj nyob ib ncig ntawm lub moos kom ruaj ntseg lub network. Qhov kev suav ua haujlwm no yuav tsum muaj zog ntau.
raws li Cambridge University, Bitcoin network siv kwv yees li 120 terawatt-teev (TWh) ntawm lub zog hauv ib xyoos - tus lej siab dua li ntau lub tebchaws hauv ntiaj teb.
Yog tias, raws li Cambridge University cov ntaub ntawv, tsuas yog 39% ntawm Bitcoin network yog siv los ntawm lub zog tauj dua tshiab, theem ntawm kev siv hluav taws xob dav dav txhais mus rau ntau lab phaus ntawm cov thee hlawv lossis ntau lab lub tsev 'kev siv hluav taws xob nruab nrab hauv ib xyoos.
Bitcoin tsis yog tsuas yog PoW-based cryptocurrency uas siv ntau lub zog. Raws li Digiconomist lub vev xaib, uas taug qab qhov tsis xav tau ntawm kev siv thev naus laus zis, Ethereum network siv txog 106 TWh ib xyoos.
Txawm li cas los xij, muaj lwm txoj hauv kev rau txoj hauv kev no, xws li proof-of-stake (PoS) kev pom zoo algorithms. Cryptocurrencies tsim los ntawm PoS-raws li blockchains tau ruaj ntseg los ntawm kev muaj cov neeg siv khoom kaw lawv tus kheej cryptocurrency es tsis muaj cov khoos phis tawj ua cov lej suav siv zog.
PoS blockchains tau hais dav dav kom tsis muaj kev puas tsuaj ib puag ncig. Alex de Vries, tus tsim ntawm Digiconomist, tsis ntev los no hais Decrypt hais tias "yog tias ntau lub tuam txhab saib xyuas, cov kev xaiv tau yooj yim tuaj yeem siv tau ntau dua."
