Matthew Green, purofesa paJohns Hopkins University, nerutsigiro rwesangano rinorwira kodzero dzevanhu reElectronic Frontier Foundation (EFF), vakatora danho rekudzosera veruzhinji kuwana kodhi yeprojekti yeTornado Cash, matura ayo akabviswa mukutanga Nyamavhuvhu. neGitHub mushure mekunge sevhisi yaiswa muzvirango rondedzero yeUS Office yeKune dzimwe nyika Asset Control (OFAC).
Iyo Tornado Cash purojekiti yakagadzira tekinoroji yekugadzira masevhisi akasarudzika ekusazivikanwa cryptocurrency transaction, iyo inonyanya kuomesera yekutevera ekufambisa cheni uye kukanganisa kuona hukama pakati peanotumira uye anogamuchira kuchinjirwa mumatiweki ane veruzhinji kuwanikwa. Iyo tekinoroji yakavakirwa pakupwanya kuchinjirwa muzvikamu zvidiki zvakawanda, kusanganisa-matanho akawanda ezvikamu izvi nezvikamu zvekutamiswa kwevamwe vatori vechikamu uye kuendesa mari inodiwa kune anogamuchira nenzira yekutevedzana kwediki kuchinjirwa kubva kwakasiyana maadhiresi kubva general dziva rebasa.
Iyo yakakura anonymizer yakavakirwa paTornado Cash yakaiswa paEthereum network uye, isati yavharwa, yakagadziridzwa kupfuura 151 zviuru zvekuchinja kubva ku12 zviuru zvevashandisi zvinosvika 7.6 bhiriyoni. Sevhisi iyi yakaonekwa sekutyisidzira kuchengetedzeka kwenyika yeUS uye yakaverengerwa murondedzero yezvirango inorambidza kutengeserana kwemari kuvagari vemuUS nemakambani. Chikonzero chikuru chakaita kuti varambidzwe kushandiswa kweTornado Cash yekubira mari yakawanikwa nenzira dzehutsotsi, kusanganisira kubiwa kwemamiriyoni mazana mana nemakumi mashanu nemashanu emadhora yakabiwa neboka raRazaro kuburikidza nebasa iri.
Mushure mekuwedzera Tornado Cash uye yakabatana cryptocurrency wallet kune zvirango zvinyorwa, GitHub yakavharira maakaundi ese evagadziri veprojekiti uye yakadzima magwaro ayo. Yekuyedza masisitimu yakavakirwa paTornado Cash, iyo isina kushandiswa mukugadzirwa kwekugadzira, zvakare yakarwiswa. Izvo hazvisati zvanyatsojeka kana kurambidza kupinda kwekodhi kwaive pakati pezvinangwa zvechirango kana kuti kubviswa kwakaitwa pasina kumanikidzwa kwakananga padanho reGitHub kudzikisa njodzi.
Chimiro cheEFF ndechekuti kurambidzwa kunoshanda pakushandiswa kwesevhisi yekushambadzira mari, asi iyo transaction anonymization tekinoroji ingori nzira yekuona zvakavanzika zvinogona kushandiswa kwete nekuda kwemhosva chete. Mhosva dzedare dzakapfuura dzakawana kuti bumbiro remitemo rinofukidzwa neFirst Amendment kuBumbiro reMitemo reUnited States, iro rinovimbisa rusununguko rwokutaura. Iyo kodhi pachayo, iyo inoshandisa tekinoroji, uye kwete chigadzirwa chakapedzwa chakakodzera kuendeswa kune chinangwa chemhosva, haigone kutariswa pasi pekurambidzwa, saka EFF inotenda kuti kutumirazve kodhi yakabviswa kare zviri pamutemo uye hazvifanirwe kuvharwa neGitHub.
Purofesa Matthew Green anozivikanwa nekutsvagisa kwake mukunyorera uye zvakavanzika, kusanganisira kugadzira iyo isingazivikanwe cryptocurrency Zerocoin uye kuve chikamu chechikwata chakafukunura backdoor muUS National Security Agency's Dual EC DRBG yemanyepo-random nhamba jenareta. Mabasa makuru aMateu anosanganisira kudzidza nekuvandudza matekinoroji ekuvanzika, pamwe nekudzidzisa vadzidzi nezvehunyanzvi hwakadaro (Mateo anodzidzisa makosi esainzi yekombuta, application cryptography, uye asingazivikanwe cryptocurrencies paJohns Hopkins University).
Anonymizers seTornado Cash mienzaniso yekubudirira kwekuita tekinoroji yekuvanzika, uye Matthew anotenda kuti kodhi yavo inofanirwa kuramba iripo pakudzidza nekumwe kusimudzira tekinoroji. Pamusoro pezvo, kunyangarika kwereferensi repository kunotungamira mukuvhiringidzika uye kusava nechokwadi kuti ndeapi maforogo anogona kuvimbwa nawo (vapambi vanogona kutanga kugovera maforogo nekuchinja kwakashata). Iwo akadzimwa marepositori akagadzirwazve naMateo pasi pesangano idzva remupupuri-repositories paGitHub kusimbisa kuti kodhi iri mubvunzo yakakosha kuvatsvagiri vezvidzidzo nevadzidzi, uye kuyedza fungidziro yekuti GitHub yakabvisa marepositori ichiteedzera zvirango, uye zvirango zvakashandiswa kurambidza kodhi yekudhinda.
