51% ntawm Ethereum Blocks Tam sim no tuaj yeem Censored. Nws yog lub sijhawm rau Flashbots kaw

Ntau thiab ntau Ethereum blocks tau tsim los ntawm censorious MEV-Boost relays, qhov tseem ceeb tshaj plaws yog Flashbots. Yog tias nws yeej muaj Ethereum qhov kev txaus siab zoo tshaj plaws ntawm lub siab, tej zaum lub koom haum MEV yuav tsum xav txog kev txo qis nws cov haujlwm kom txog thaum cov neeg tsim khoom tuaj yeem siv cov kev daws teeb meem mus sij hawm ntev.

51% ntawm Blocks Hauv Censorship hem

Ethereum's MEV censorship teeb meem yog zuj zus los ntawm hnub.

raws li MEV Watch, 51% ntawm Ethereum cov blocks uas tsim los nag hmo tau tsim los ntawm qhov hu ua "OFAC raws" MEV-Boost relays, lub ntsiab lus relays uas tau qhib siab hais tias lawv lub hom phiaj rau censor pauv cuam tshuam nrog Tornado Nyiaj ntsuab lossis lwm yam kev cai tswj hwm los ntawm US Treasury yav tom ntej.

MEV, los yog "Maximum Extractable Value," yog ib lo lus uas siv los piav txog cov hauv kev arbitrage pom los ntawm reordering muas nyob rau hauv ib qho thaiv thaum nws tab tom tsim. flashbots thiab lwm yam MEV-Boost relays qhov tseem ceeb yog muab kev lag luam tawm ntawm kev lag luam thaiv kev lag luam rau cov tub lag luam thiab cov neeg siv khoom siv. Raws li Flashbots cov ntaub ntawv, MEV tau rho tawm ntau dua $ 675 lab los ntawm cov neeg siv blockchain txij thaum Lub Ib Hlis 2020. 

Txij li thaum Ethereum hloov mus rau Kev Pom Zoo-ntawm-Stake-kev pom zoo mechanism, Flashbots thiab lwm yam MEV-Boost relays tau ua lub luag haujlwm rau kev tsim kom muaj ntau ntxiv ntawm Ethereum blocks. Raws li MEV saib cov ntaub ntawv, 90% ntawm cov blocks tau tsim rau lub Cuaj Hlis 15 yam tsis siv MEV-Boost relays; Tus lej ntawd tau nqis mus rau 43% txij li lub Kaum Hlis 14. Qhov no xav tau, vim tias cov neeg siv khoom siv tau tuaj yeem ua tiav cov txiaj ntsig siab dua los ntawm kev tawm tswv yim los ntawm lawv cov haujlwm thaiv kev tsim kho rau MEV-Boost relays.

Qhov teeb meem yog qhov loj tshaj plaws MEV-Boost relays, tshwj xeeb tshaj yog Flashbots, tau qhib siab hais tias lawv yuav tsis kam suav nrog kev lag luam ntsig txog Tornado Nyiaj hauv cov blocks lawv tsim. Yog vim li cas rau qhov ntawd yog Lub Chaw Haujlwm Saib Xyuas Kev Ruaj Ntseg Txawv Tebchaws (OFAC) ntxiv Txoj cai tswjfwm ntiag tug rau nws cov npe rau txim rau lub Yim Hli 8, sib cav tias nws tsuas yog siv los ntawm cov neeg launderers thiab North Kauslim cybercriminals. Tom qab qhov txwv tsis pub, cov kev pabcuam tseem ceeb hauv crypto txiaj xws li Circle thiab Infura tsiv rau blacklist Ethereum chaw nyob, thiab Flashbots yog ntawm cov koom haum tshaj tawm sai sai nws "OFAC ua raws." 

Pushback los ntawm Ethereum zej zog tau ua rau Flashbots rau tso tawm nws relay code raws li qhib qhov chaw; Txawm li cas los xij, Flashbots relay tseem yog lub luag haujlwm rau yuav luag 80% ntawm tag nrho MEV-Boost relay block ntau lawm. Hauv 24 teev ua ntej lub sijhawm sau ntawv, ntau dua 57% ntawm tag nrho Ethereum blocks tau tsim los ntawm MEV-Boost relays; Ntawm cov no, 88% tau tshaj tawm hais tias lawv yuav tsis kam suav nrog kev lag luam hauv txhua txoj kev cuam tshuam nrog Tornado Nyiaj. Raws li tau hais dhau los, qhov ua tau zoo txhais tau hais tias 51% ntawm tag nrho cov blocks tau tsim los ntawm relays nyiam nrog censoring Ethereum yog tias xav tau.

Ua Dab Tsi?

Cov tswv cuab ntawm Ethereum cov neeg zej zog tau taw qhia txog qhov teeb meem no txog ib hlis tam sim no, tab sis qee qhov kev daws teeb meem zoo li tau muab tso rau tom ntej: qhov phem dua, nws zoo li cov tswv cuab tseem ceeb hauv zej zog tau zam kev daws qhov teeb meem nrog kev ceev ceev. Thaum twg Crypto Briefing keeb xeeb them qhov kev tsis sib haum xeeb me ntsis ntau tshaj li ob lub lis piam dhau los, tag nrho ntawm 25% ntawm tag nrho Ethereum blocks tsim txij li lub Cuaj Hlis 15 tau tsim los ntawm censorious relays. Tus lej ntawd tam sim no sawv ntawm 34% thiab tau nce sai.

Bitcoin tus kws lij choj Eric Wall tau yog ib tus thawj coj hu tawm qhov kev censorship. Phab ntsa muab a kev nthuav qhia ntawm Devcon nag hmo uas nws tau sib cav tias muaj ntau txoj hauv kev los daws qhov teeb meem censorship, suav nrog los ntawm kev tsim cov Proposer Builder Separation (PBS) infrastructure, Inclusion Lists, lossis Partial Block Auctions. Hmoov tsis zoo, cov kev daws teeb meem no tseem xav tau kev tshawb fawb thiab tuaj yeem siv ntau lub hlis lossis xyoo los siv. Cov tswv yim tib yam no tau muaj sib tham nyob rau hauv lub rooj sab laj Flashbots; Qhov tseem ceeb heev, tus tsim Ethereum Vitalik Buterin Hais tias PBS yuav "qhov tseeb" yog ob mus rau yim xyoo hauv kab.

Tab sis thaum Ethereum cov neeg tsim khoom yuav tsum xav txog txoj hauv kev los hloov lub blockchain cov txheej txheem los kho qhov tsis zoo no, nws nyuaj tsis txhob thuam Flashbots thiab lwm yam MEV-Boost relays rau lawv tus cwj pwm thoob plaws qhov kev sib cav no. Raws li Gnosis co-founder Martin Köppelmann, ntau tus tswv cuab ntawm pab pawg Flashbots cog lus kom "ua yeeb yam yog tias censorship [ua] phem dua," tab sis me ntsis tau los ntawm lub koom haum txog tam sim no. Flashbots tseem tsis tau hais tawm rau pej xeem cov lus piav qhia yog vim li cas lawv ntseeg hais tias lawv yuav tsum censor Tornado Nyiaj ntsuab pauv txawm tias US Treasury tsis tau qhia meej txog US block producers ua li ntawd. Ua thawj crypto pauv pauv Coinbase thiab Kraken, ob ntawm Ethereum qhov kev lees paub loj tshaj plaws, tsis muaj teeb meem dab tsi nrog kev ua Tornado Nyiaj Txiag hauv lawv cov blocks. Vim li cas Flashbots xav txawv? Lub koom haum tsis tau txiav txim siab los ua qhov kev sib cav.

Flashbots co-founder Stephane Gosselin kuj tseem yuav tsis pom zoo nrog lub koom haum cov kev taw qhia. Gosselin tshaj tawm Lub lim tiam dhau los uas nws tau tawm ntawm Flashbots dhau ntawm "kev tsis pom zoo nrog pab pawg." Thaum nug kom nthuav dav ntawm qhov tsis pom zoo, Gosselin tau hais tias nws yuav, "cia siab tias yuav sai sai no." Tsim nyog bearing hauv siab yog tias Gosselin muaj yav tas los suab kev pom zoo rau qhov muaj peev xwm txhim kho lub slashing mechanism tiv thaiv relays lawv tus kheej.

Lwm cov tswv cuab ntawm Flashbots siab heev tau ua ntsiag to. Flashbots lub tswv yim ua rau Hasu nyuam qhuav retweeted xov piav qhia tias, txij li Lub Kaum Hli 12, tsuas yog 0.617% ntawm Ethereum blocks tau koom nrog Tornado Cash kev lag luam txhua, thiab Tornado Cash kev lag luam muaj 99% txoj hauv kev tau txais los ntawm cov neeg tsim khoom lag luam hauv tsib blocks. Tab sis txoj kab ntawm kev xav no zoo li tus tub ceev xwm tawm: tsuas yog vim Tornado Nyiaj ntsuab pauv (tam sim no) tseem tuaj yeem tau txais los ntawm lwm tus neeg tsim khoom thaiv tsis tau txhais hais tias Flashbots tsis hem qhov nruab nrab ntawm Ethereum network.

Flashbots co-founder Phil Daian kuj tau txo qis kev thuam. Thaum Köppelmann tau txiav txim siab txog tus naj npawb ntawm cov blocks ua tiav los ntawm censorious MEV-Boost relays, Daian yooj yim retweeted ib tsab ntawv hais tias "Gnosis yuav tsum khiav ib qho kev sib txuas," hais tias yog Köppelmann tsis txaus siab rau txoj kev Flashbots tau tuav nws txoj haujlwm, nws yuav tsum teeb tsa kev lag luam sib tw. Zoo kawg, Daian kuj Hais tag kis no hais tias "kev ncaj ncees ntawm peb lub lag luam yog ib qho tseem ceeb heev rau [Flashbots]" thaum ib tug neeg liam tias Flashbots khiav nws tus kheej searcher - txhais tau hais tias nws yuav nrhiav MEV lub sij hawm nyob rau tib lub sij hawm raws li nws tau muab kev pab cuam MEV-Boost. Nws yog qhov nyuaj heev los coj Daian thiab pab pawg Flashbots lub siab ncaj ncees hauv av tiag tiag thaum lawv tau pom tias lawv txaus siab rau censor Ethereum nws tus kheej.

Flashbots feem ntau pom tias yog lub zog zoo thaum nws los txog rau MEV. Lub koom haum tau pab loj "txo qhov tsis zoo sab nraud" ntawm MEV rau cov neeg siv Ethereum txog tam sim no, raws li nws hais hauv nws lub vev xaib. Tab sis qhov kev hem thawj Flashbots ua rau Ethereum qhov nruab nrab yog qhov sib cav tseem ceeb dua li cov kev pabcuam nws tam sim no muab. Flashbots tsis yog qhov tseem ceeb rau Ethereum txoj kev ciaj sia - raws li tau lees paub los ntawm qhov tseeb tias 43% ntawm cov neeg siv khoom siv tsis xav tias yuav tsum siv MEV-Boost relays txhua. Yooj yim yooj yim, yog tias Flashbots tsis tuaj yeem coj nws tus kheej kom siv tau Tornado Nyiaj ntsuab kev lag luam tawm ntawm kev ntshai ntawm qhov ua tau OFAC qhov tshwm sim, nws yuav tsum ua kom nws cov haujlwm ua haujlwm kom txog thaum Ethereum core developers pom ib txoj hauv kev los hloov blockchain cov txheej txheem los ua kom censorship ua tsis tau. Flashbots tsis yog tib lub npe hu ua "OFAC raws" MEV-Boost relay, tab sis nws yog qhov loj tshaj plaws, thiab nws tseem muaj kev saib xyuas zoo hauv zej zog crypto.

Nws yuav yog nyob rau hauv Ethereum ecosystem qhov kev txaus siab zoo tshaj plaws rau Flashbots los pib qhov no thiab ua qhov nyuaj. Nws kuj tseem yuav ua rau Flashbots pib tshiab xws li SUAVE, "tus tsim kev lag luam tag nrho" uas yog tshaj tawm hnub no ntawm Devcon, yooj yim dua kom tau zoo siab rau, txij li ua kom meej meej ua Flashbots MEV-Boost relay code qhib qhov chaw tsis tau txaus los daws cov teeb meem censorship txog tam sim no.
