Tus khub thiab tus kws qhia ntawv ntawm Harvard Kennedy Tsev Kawm Ntawv, Bruce Schneier, tau tham txog decarbonizing cryptocurrencies los ntawm kev them se hauv blog ncej Lub Ib Hlis 4, qhia tias nws yog qhov tsim nyog los yuam cov neeg yuav khoom them nyiaj rau lawv qhov kev puas tsuaj ib puag ncig los ntawm crypto se.

Lub sijhawm zoo tshaj plaws rau decarbonize qhov chaw crypto
Raws li ntau cryptocurrencies poob qis thiab FTX Kev lag luam nyiaj txiag nkag mus rau theem kev sib hais plaub, Schneier ntseeg tias cov tub ceev xwm yuav tshawb xyuas lub lag luam cryptocurrency tam sim no ntau dua li qhov qub, yog li muab lub sijhawm zoo los tiv thaiv lawv cov kev puas tsuaj ib puag ncig.
Tus kws sau ntawv Amelikas sau tseg li cas Ethereum, hloov los ntawm Pov Thawj-of-Work (PoW) rau Ntawv pov thawj-of-Ceg Txheem Ntseeg (PoS) nyob rau hauv 2022, uas ua rau nws lub zog noj poob los ntawm ntau tshaj 99.9% 'dhau hmo,' Txawm li cas los, nws ntseeg hais tias Bitcoin thiab lwm yam cryptocurrencies tej zaum yuav tsis ua raws li txoj kev no "tshwj tsis yog yuam kom, vim hais tias pov thawj-of-Work muaj loj heev. profits rau miners - thiab lawv yog cov uas muaj hwj chim nyob rau hauv lub system. "
Schneier sau tseg tias kev ntiav cov se es tsis txhob txwv tsis pub tshaj tawm yuav ua rau cov teeb meem ntawm kev txwv tsis pub mining uas tau tsiv mus rau lwm lub tebchaws thaum Tuam Tshoj tau txwv txoj cai hauv xyoo 2018.
"Raws li cov se ntawm cov roj av, luam yeeb, plastics, thiab cawv, cov se cryptocurrency tuaj yeem txo qhov kev puas tsuaj hauv ntiaj teb los ntawm kev ua rau cov neeg siv khoom them rau nws. Feem ntau ntawm kev them se cryptocurrencies yuav tsis muaj txiaj ntsig, vim tias lawv yooj yim rau kev hla thiab nyuaj rau kev tswj hwm. Txhawm rau zam cov teeb meem no, cov se yuav tsum tau them se raws li qhov feem pua ntawm txhua qhov pov thawj-ntawm-ua haujlwm-cryptocurrency muas. "
Kev sib pauv Cryptocurrency, nws sau tseg, yuav tsum sau cov se ib yam li cov tub lag luam ua ntej xa nyiaj mus rau tsoomfwv uas nws hais tias yuav yog 'pob tshab thiab yooj yim rau kev tswj hwm.'
