Qhov xwm txheej ntawm 51% ntawm OFAC-raws li blocks ntawm Ethereum ua rau lub neej yav tom ntej ntawm lub network, nthuav tawm nws kom muaj kev pheej hmoo siab ntawm kev ua txhaum cai ntawm nws qhov kev tawm tsam, lossis tseem phem dua, ua txhaum ntawm decentralization ntawm qhov thib ob tseem ceeb tshaj plaws blockchain.
MEV-boost Relays
Tom qab Ethereum hloov mus rau Pov Thawj-of-Stake, kev txhawj xeeb txog kev tswj hwm censorship, uas tau ceeb toom yav dhau los, loj hlob dua tom qab blockchain thiab web 4 txoj kev loj hlob tuam txhab Labrys tau tshaj tawm ntau ntxiv ntawm MEV-boost relays ua raws li Lub Chaw Haujlwm Saib Xyuas Kev Ruaj Ntseg Txawv Tebchaws ( OFAC).
Cov lus tseem ceeb tau nthuav dav thoob plaws hauv zej zog Twitter. Cov neeg lag luam tuaj txog qhov xaus tias Ethereum tam sim no yog qhov cuab yeej zoo tshaj plaws rau tsoomfwv censorship vim feem ntau ntawm Ethereum blocks post Merge tam sim no tau tsim siv OFAC-raws li MEV-boost relays.
Martin Köppelmann, tus kws ua lag luam blockchain thiab tus thawj coj tau hais hauv Tweet:
"Peb tau mus txog qhov tseem ceeb tshaj plaws hauv kev censorship: 51% ... Qhov no txhais tau tias yog tam sim no censoring validators yuav tsum tsis lees paub rau qhov tsis-censoring blocks lawv yuav kawg tsim cov canonical, 100% censoring saw."
MEV (Qhov Tshaj Tawm Tshaj Tshaj Tshaj Tshaj Tshaj Tshaj) tsis yog lub sijhawm coj txawv txawv yog tias koj paub txog Ethereum network. MEV, luv luv, sawv cev rau tus nqi uas PoW miners tuaj yeem ua kom zoo dua los ntawm kev xaj kev lag luam.
Cov txheej txheem MEV, ntawm qhov tod tes, tau hloov kho raws li qhov tshwm sim ntawm kev hloov kho loj Merge.
Tus thawj MEV tau "hloov kho" nrog kev tso tawm ntawm MEV-Boost, thawj qhov kev rov ua dua tshiab ntawm Tus Tswv Tsim-Kev Sib Cais. Siv cov tswv yim no, validator nodes nyob rau hauv lub network muaj peev xwm nce lawv cov txiaj ntsig rau lawv lub peev xwm tag nrho.
Separating validator nodes, uas muaj cov blocks, los ntawm cov neeg tsim cov nodes, uas ua blocks, tsim ib lub lag luam uas ua rau qhov zoo tshaj plaws kev siv ntawm staking khoom plig. Yog li, cov neeg siv khoom siv hluav taws xob uas siv MEV-Boost tuaj yeem muag cov neeg tsim khoom ntawm qhov chaw teem tseg rau cov blocks.
Cov txheej txheem ua kom paub tseeb tias MEV-Boost qhov tseem ceeb tau muab faib ua qhov ncaj ncees kom cov pas dej loj tshaj plaws uas muaj cov blocks tsis txhob sim ua kom lawv cov nyiaj tau los ntau tshaj plaws ntawm cov nqi ntawm lwm tus.
Lub hauv paus code rau MEV-Boost yog qhib qhov chaw, thiab Flashbots ua nws. Tom qab ntawd, validators uas siv nws tuaj yeem txhawb nqa lawv cov txiaj ntsig koom nrog kwv yees li 60%.
Txoj kev, txawm li cas los xij, tuaj yeem raug nqi Ethereum censorship resistance. MEV-boost relays tuaj yeem xaiv cov kev lag luam uas lawv suav nrog hauv lawv cov blocks.
Raws li cov neeg tswj hwm tau ua qhov nyuaj ntxiv rau kev lag luam crypto, muaj qhov tshwm sim siab uas lawv mus tom qab qee qhov chaw nyob thiab xav kom censor pauv nrog cov chaw nyob.
Qhov Kawg Ntawm Censorship Resistance?
Martin cov lus hais saum toj no ua rau lub ntsiab lus zoo uas cov neeg saib xyuas kev lees paub tuaj yeem txiav txim siab lub xeev feem ntau ntawm cov neeg lees paub pom zoo nrog 51% feem, uas yuav txhais tau tias 100% ntawm cov blocks raug censored.
Txawm li cas los xij, nws yog ib qho tseem ceeb kom nco ntsoov tias feem ntau ntawm cov blocks tsis vam khom rau MEV-boost, raws li Blockwork Research. Ntawm qhov tod tes, lub tuam txhab Flashbots, tus tsim ntawm MEVBoost tau cog lus tias yuav qhib qhov chaw ntau dua ntawm lawv tus IP kom txo tau Ethereum qhov kev cia siab ntawm lawv cov relay.
OFAC (Office of Foreign Assets Control) yog US Treasury Department lub koom haum saib xyuas kev tswj hwm thiab kev siv lub teb chaws kev nplua nyiaj txiag thiab kev lag luam. Nws tau pom zoo txuas nrog qhov xwm txheej Tornado Cash.
Ethereum cryptocurrency mixer raug liam tias raug siv los ntawm cov neeg ua txhaum cai rau kev ua haujlwm nyiaj txiag, suav nrog cov neeg tsis muaj npe North Kauslim hacking pab pawg. Raws li tau tshaj tawm, ntau tshaj li ib nrab ntawm MEV-Boost relay blocks tau ua raws li OFAC-tswj cov txheej txheem txij thaum Lub Kaum Hli 14.
Nws yog ib lub hlis txij li Ethereum network tau tshaj tawm Lub Merge, yog ib qho kev txhim kho tseem ceeb tshaj plaws hauv keeb kwm cryptocurrency. Qhov hloov tshiab loj tau xav tias thaum kawg yuav ua rau lub network muaj zog-sustainable thiab ua haujlwm tau zoo.
Contrary to common assumpions, lub lag luam cryptocurrency tseem gloomy. Qhov no yog qhov teeb meem uas cuam tshuam rau txhua qhov kev siv cryptocurrency. Coinbase tsis ntev los no tau kaw qhov teeb meem ETH deflationary thawj zaug.
Ua ntej qhov teeb meem ntawm censorship, Ethereum cov tub ua lag luam tau cuam tshuam nrog cov nqi siab heev. Thaum cov tub ua lag luam tuaj yeem muaj sia nyob nrog tus nqi siab, lawv yuav xav txog yav tom ntej ntawm Ethereum raws li kev ua tiav censorship tsis kam muaj kev pheej hmoo.
