Ethereum tus tsim tawm Evan Van Ness tau hais txog kev txhawj xeeb txog bitcoin's (BTC) mining centralization, taw qhia tias sab saum toj ob lub pas dej mining tswj ntau tshaj li ib nrab ntawm tag nrho cov hashrate.
Hauv lub Kaum Ob Hlis 27 Twitter xov, Van Ness hais tias tawm ntawm 1,000 kawg bitcoin blocks, 501 tau mined los ntawm Antpool thiab Foundry USA mining pas dej - qhia txog kev tswj feem ntau ntawm hashrate. Daim ntawv qhia ntawm bitcoin hashrate faib los ntawm BTC.com raws li peb hnub ntawm cov ntaub ntawv qhia uas Foundry USA tam sim no tswj 31.1% ntawm cov hashrate, thaum Antpool 21.1%, rau tag nrho ntawm 52.2%.
Van Ness tau hais txog "qhov tsis txaus ntseeg" los ntawm crypto-focused xov xwm tshaj tawm Coindesk. Zaj lus thuam ethereum hais txog lub network lub hauv paus hauv qab no The Merge thiab hloov mus rau pov thawj-ntawm-stake (PoS). Thaum lub Cuaj Hlis tsab xov xwm, Coindesk hais txog tus co-founder ntawm lub tuam txhab cryptocurrency tsa qhov teeb meem uas "tawm ntawm 1,000 blocks kawg, 420 tau tsim los ntawm Lido thiab Coinbase xwb." Van Ness commented:
Van Ness kuj tau sau tseg tias thaum lub sijhawm ntawm tsab xov xwm tshaj tawm, bitcoin's block ntau lawm yog qhov tseem ceeb tshaj li Ethereum's. Piv txwv li, ob lub pas dej sib cais mined mined 430 ntawm qhov tseeb 1,000 blocks. Nws tau piav qhia tias nws tau yws txog "ob tus qauv" thiab tau thov tias "Ethereum thiab Bitcoin yog nyob deb ntawm cov chains feem ntau decentralized." Nws xaus lus:
"Kuv xav sib cav tias Ethereum yog qhov muaj feem cuam tshuam ntau dua, tab sis nws tsawg kawg yog kev sib cav."
Cov pas dej mining yog dab tsi thiab yog vim li cas thiaj muaj teeb meem?
Lub pas dej bitcoin mining yog ib pab pawg miners uas sib txuas lawv cov kev siv nyiaj txiag los txhawb lawv txoj hauv kev los nrhiav qhov thaiv thiab tau txais txiaj ntsig. Thaum pom ib qho thaiv, cov khoom plig tau muab faib rau ntawm cov tswv cuab hauv pas dej ua ke raws li lawv txoj kev koom tes rau kev suav lub zog.
Cov pas dej tsuas yog tsim nyog vim tias qhov tshwm sim ntawm kev nrhiav ib qho thaiv hauv bitcoin network ib leeg yog tsawg heev. Los ntawm kev koom nrog lub pas dej mining, miners tuaj yeem ua rau lawv txoj hauv kev los nrhiav qhov thaiv thiab tau txais txiaj ntsig. Tsis tas li ntawd, cov pas dej mining tso cai rau cov neeg tuaj koom tau txais cov nyiaj tau los tsis tu ncua es tsis tos qhov kev tshawb pom tsis tshua muaj.
Nyob rau tib lub sijhawm, Bitcoin mining pas dej ua ke tau dhau los ua qhov mob tseem ceeb rau lub network decentralization txij li cov chaw no xaiv cov kev lag luam thiab cov ntsiab lus ntawm cov blocks mined los ntawm ntau cov miners. Mining pas dej GHash.io yog ib qho piv txwv tsis zoo txij li thaum nws mus txog kev tswj hwm ntau dua 51% ntawm lub network hashrate hauv 2014. Lub pas dej tom qab cog lus kom tsis txhob tswj ntau tshaj 40% ntawm hashrate yav tom ntej.
Mining pas dej ua ke yuav tsum tswj tsuas yog ib feem me me ntawm tag nrho cov hashrate ntawm ib tug cryptocurrency network. Nws pab kom muaj kev ywj pheej thiab kev ruaj ntseg. Thaum ib lub pas dej mining muaj ib feem tseem ceeb ntawm lub network hashrate, nws ua rau muaj kev cuam tshuam ntau dua rau 51% kev tawm tsam, uas ib lub koom haum tuaj yeem cuam tshuam rau lub network los ntawm kev tswj hwm feem ntau ntawm nws lub zog suav.
Hauv 51% kev tawm tsam, ib lub koom haum uas tswj hwm feem ntau ntawm cov hashrate tuaj yeem cuam tshuam kev ncaj ncees ntawm lub network thiab koom nrog kev ua phem, xws li thim rov qab kev lag luam lossis kev siv nyiaj ob npaug. Nws yeej tsis tau tshwm sim rau bitcoin, tab sis nws tau tshwm sim ntawm blockchains qhov twg qis dua hashrate ua rau cov kev tawm tsam zoo li no.
Hauv 2019, ethereum classic (ETC) raug mob 51% nres, nrog crypto pauv Gate.io txheeb xyuas tsawg kawg yog xya ob zaug siv nyiaj. Nyob rau hauv 2018 vertcoin raug kev txom nyem plaub cais tawm tsam uas ua rau lub tub sab txog $100,000. Kev siv nyiaj ob npaug ua ntawm bitcoin kub (BTG) network hauv tib lub xyoo ua rau ntau dua $ 18 lab raug nyiag. Thaum kawg, hauv 2013, litecoin diav rawg, feathercoin (FTC), kuj raug kev puas tsuaj 51%.
