Bitcoin developers yog tham txog Cov kab laum Lightning Network tshiab uas tuaj yeem ua rau tsis muaj kev them nyiaj routing tsis ua haujlwm. Cov kab no tuaj yeem ua rau xob laim Network them nyiaj poob haujlwm yam tsis muaj ob tog koom nrog paub vim li cas.
Raws li kev tawm tsam rau txheej txheej Bitcoin qhov twg ntau txhiab tus neeg ua haujlwm ntawm cov neeg siv khoom siv tau siv tau, Kev them nyiaj xob laim tuaj yeem koom nrog tsawg li ob tus neeg. Cov neeg siv lub hom phiaj txi qhov kev ruaj ntseg ntawm Bitcoin's blockchain hauv kev pauv rau kev nrawm dua thiab cov nqi pheej yig dua.
Nyob rau hauv lub Lightning Network, kev them nyiaj tuaj yeem ua tsis tiav yog tias muaj dab tsi mus tsis ncaj ncees lawm nrog ib kauj ruam hauv ntau yam txheej txheem kos npe. Piv txwv li, qhov kawg receiver yuav tsis kam tso ib tug preimage lees paub tias lawv tau txais cov nyiaj them, los yog ib tug xob laim Network node tej zaum yuav offline.
Ib qho kev them nyiaj tsis raug them nqi tsis ua haujlwm txhais tau hais tias qhov cov neeg siv nyiaj yuav tsis paub tias qhov twg mus tsis ncaj ncees lawm. Txawm hais tias cov lus yuam kev tau ua txhaum ntawm txoj kev rov qab mus rau tus neeg xa khoom, lossis lawv tsis tau txais cov lus. Tej zaum lawv yuav sim siv lub faulty node yam tsis tau paub tias muaj teeb meem.
Yog tias cov neeg siv nyiaj tau txais kev ceeb toom txog qhov tsis raug, lawv tuaj yeem sim dua tom qab ua qee qhov kev hloov kho, xws li hloov mus rau qhov sib txawv Lightning Network node.
Muaj peev xwm daws teeb meem rau qhov kev them nyiaj tsis raug cai tsis ua haujlwm
Tus tsim tawm Joost Jager cia siab tias qhov teeb meem no thiab npaj siab ib qho kev daws teeb meem hauv 2019. Nws pom tias kev them nyiaj channel tuaj yeem siv sijhawm ntev kom paub meej tias qhov kev hloov pauv mus dhau. Nws pom zoo kom ntxiv ob lub sijhawm rau cov lus uas cov nodes xa rov qab mus rau tus neeg xa khoom xa tuaj. Ib daim ntawv teev sijhawm yuav sawv cev rau lub sijhawm uas cov node tau txais qhov kev sib pauv thiab lwm lub sijhawm thaum lub sijhawm sib pauv hloov pauv mus rau nws qhov chaw nres tsheb tom ntej. Ob daim ntawv teev sijhawm yuav muab cov neeg xa khoom ib lub tswv yim ntawm cov channel twg qeeb rau kev hloov pauv hloov pauv thiab zam cov channel yav tom ntej.
Lub Kaum Hli 19, 2022, Jager tso tawm ib qho tshiab version ntawm nws unattributed them routing kho uas yuav txhim kho cov lus tsis ua hauj lwm kom lawv yuav tsis zoo li gibberish rau ib tug sender. Cov lus txhim kho yuav tso cai rau cov neeg xa khoom tuaj yeem txheeb xyuas qhov tseeb ntawm qhov ua rau lawv cov kev lag luam ua tsis tiav kom lawv tuaj yeem tshem tawm ntawm kev lag luam yav tom ntej.
Xeb russell pom tias Lwm txoj hauv kev: Txhua qhov routing node yuav raug them ib zaum txawm tias qhov kev hloov pauv tsis ua haujlwm. Cov neeg xa xov tuaj yeem qhia tau qhov twg routing node ua tsis tiav los ntawm Muab piv cov naj npawb ntawm satoshis xa nrog tus naj npawb ntawm satoshis lawv tau txais rov qab. Qhov kev suav satoshi no yuav ua haujlwm txawm tias cov lus yuam kev tau ua tsis raug. (Faj seeb: Ib satoshi sib npaug ib puas lab ntawm bitcoin.)
LND kev siv ntawm Lightning Network plagued nrog yuam kev
Lub Kaum Ib Hlis 1, 2022, Lightning Labs tso tawm kev hloov kho xwm txheej kub ntxhov los kho cov kab laum uas ua rau LND nodes ua tsis tiav los txheeb xyuas cov kev lag luam uas xav tau ntau cov lus pov thawj. Cov nodes uas tsis hloov tshiab yuav ua tsis tau tejyam los tiv thaiv kev phem channel kaw thaum lub sij hawm kaw lawm.
Tus tsim tawm hu ua "Burak" triggered tus kab mob nrog kev sib pauv uas muaj cov lus, "koj yuav khiav CLN [Core Lightning] thiab koj yuav zoo siab."
Burak ua rau muaj kab laum zoo sib xws thaum Lub Kaum Hli 9, 2022, thaum tus tsim tawm tsis qhia npe tau xa 998-ntawm-999 tapscript multisig pauv. Hom kev lag luam no yuav xav tau 998 tus lej tseem ceeb kos npe rau kev lees paub, ua rau nws nyuaj rau thawb nws kom tiav. Nws khav theeb hais txog ua nws rau tus nqi $4.90.
Nyeem ntxiv: Kab laum freezes bitcoin hauv Lightning Network rau teev
Tus neeg siv Twitter Stadicus hu ua kev tawm tsam ib tug "savage takedown" thiab tau hais kom pib qhov kev pab cuam bug bounty.
Ib tug hacker hu ua Anthony Towns thov nws tau sim ceeb toom rau Lightning Network cov neeg tsim tawm txog cov kab laum, tab sis hais tias btcd repo zoo li tsis muaj ib txoj hauv kev rau kev ceeb toom cov kab mob.
Ob tus tsim tawm Lightning Network tau npaj cov kev daws teeb meem rau qhov teeb meem kev them nyiaj tsis ua haujlwm. Los ntawm kev txhim kho cov lus, Joost Jager lub tswv yim yuav ua rau nws yooj yim dua los txheeb xyuas qhov teeb meem tshwm sim. Russell lub tswv yim yuav tus nqi xa ob peb satoshis ntxiv, tseem ua rau nws muaj peev xwm taug qab qhov teeb meem txawm tias cov lus tsis rov qab mus rau tus neeg xa khoom. Lub caij no, cov neeg tsim khoom tab tom kho cov kab uas yuav ua rau LND nodes ua tsis tiav thawj zaug.
