Kubikwa ukuthi iphrothokholi ye-Umbra yathuthukiswa nguMatt Solomon noBen DiFrancesco we-HackMoney 2020 virtual hackathon, futhi okwamanje iyatholakala ku-Ethereum Ropsten testnet.
Isetshenziselwa ini?vele uthi:

“Ngekheli elingabonakali, okhokhayo angathumela amathokheni e-ETH noma e-ERC20 ekhelini elilawulwa umamukeli, futhi ngaphandle kwazo zombili izinhlangothi, akekho umuntu wesithathu ongakwazi ukwazi ukuthi ubani owamukelayo.”

Ku-chain, ukuthengiselana kubukeka sengathi kumane kudluliselwe ekhelini elingasetshenzisiwe kunethiwekhi ye-Ethereum.

Umfanekiso: Buka ukuthengiselana kwe-ETH usebenzisa iphrothokholi ye-Umbra ku-Etherscan.Ochungechungeni, ikheli elingabonakali libukeka njengekheli elivamile le-EOA.

Ngaphandle kochungechunge, umthumeli usebenzise i-ENS ukuze akhiqize ikheli elisha ngokhiye womphakathi okhishwe umamukeli.Ngokubhala ngekhodi idatha esetshenziswe ukukhiqiza ikheli, futhi ngenkontileka ehlakaniphile ye-Umbra, umthumeli angazisa umamukeli ukuthi uthumele inkokhelo ekhelini elisha elingabonakali.Umamukeli kuphela ongakwazi ukukhiqiza ukhiye oyimfihlo odingekayo ukuze kukhishwe imali.

Ngokusebenzisa inethiwekhi yeGas Station kanye ne-Uniswap, i-Uniswap inika amandla ukuhoxa ukuze kusetshenziswe amathokheni abawatholayo ukuze bakhokhele igesi.Lokhu kugwema isidingo sokusebenzisa i-ETH ukuxhasa amakheli angabonakali ngaphambi kokukhipha imali.
Umehluko phakathi kwe-Umbra neTornado Cash

Uyini umehluko phakathi kwe-Umbra neTornado Cash uVitalik avame ukuyikhuluma?

Kalula nje, i-Tornado Cash iyinhlanganisela yezinhlamvu zemali eku-on-chain esebenzisa ubufakazi obungenalo ulwazi.Uma ufaka izinhlamvu zemali kuwo bese ulinda abanye ukuba benze okufanayo, ungasebenzisa owakho ubufakazi ukuze ukhiphe izimpahla.Kugxilwe kusihlanganisi, ngakho isixhumanisi phakathi kwekheli lomthombo nekheli lokuhoxiswa siphukile.

Iphrothokholi ye-Umbra isetshenziselwa ukukhokha phakathi kwezinhlangano ezimbili, futhi iza nesethi ehlukile yokuhwebelana kwangasese (okungukuthi, kucatshangelwa izikhombisi-ndlela ezihlukene).I-Umbra ayiphuli isixhumanisi phakathi kwamakheli omthumeli nomamukeli, kodwa yenza izixhumanisi zingabi nanjongo.Wonke umuntu angazi ikheli okuthunyelwa kulo izimali, kodwa ngeke azi ukuthi ubani olawula lelo kheli.

Ngaphezu kwalokhu, iphrothokholi ye-Umbra nayo inezici ezithakazelisa kakhulu.Isibonelo, isebenzisa igesi encane kakhulu ngoba ayidingi ubuchwepheshe bokubethela obuthuthukisiwe ochungechungeni lokuqinisekisa.Konke ukuthengiselana kungukudlulisa okulula.Ngaphezu kwalokho, ivumela i-ETH nanoma imaphi amathokheni e-ERC20 ukuthi adluliselwe ngokuyimfihlo, awudingi ukuncika kusethi enkulu engaziwa.

Incazelo yesimiso sokusebenza se-Umbra protocol

Okokugcina, khuluma kafushane ngokuthi iphrothokholi ye-Umbra isetshenziswa kanjani:

Umsebenzisi uthumela umlayezo osayiniwe kwirekhodi lombhalo le-ENS ukuze abonise ukhiye wabo osesidlangalaleni we-Umbra.Lo khiye osesidlangalaleni uthathwe kukhiye oyimfihlo ongahleliwe owakhelwe ngokuqondile i-Umbra.
Umkhokhi usebenzisa lo khiye osesidlangalaleni, kanye nedatha ethile ekhiqizwa ngokunganaki, bese edala ikheli elisha “elingabonakali”.
Umkhokhi usebenzisa ukhiye osesidlangalaleni womamukeli ukuze abethele idatha engahleliwe.
Umkhokhi uthumela imali ekhelini elivikelwe futhi athumele umlayezo ofihliwe kunkontileka ehlakaniphile ye-Umbra.Inkontileka isakaza umlayezo obethelwe njengomcimbi.
Umamukeli uskena umlayezo obethelwe osakazwa yiphrothokholi ye-Umbra aze athole umlayezo ongasuswa ukubethela ngokhiye oyimfihlo.
Umamukeli usebenzisa okuqukethwe komlayezo obethelwe kanye nokhiye wabo oyimfihlo ukuze akhiqize ukhiye oyimfihlo wekheli elingabonakali.
Umamukeli usebenzisa ukhiye oyimfihlo wekheli elingabonakali ukuze asayine umsebenzi wokuhoxiswa futhi athumele i-ETH noma ithokheni ekhelini alithandayo.
Enye enye indlela ukuthi ukuhoxiswa kokuhoxiswa kusakazwa nge-Relayer transaction network ye-Gas Station, ukugwema isidingo sokuhlinzeka ngezimali ze-ETH zokufinyelela ekhelini elingabonakali lethokheni.Inkontileka ye-Umbra ishintsha amathokheni athile nge-Uniswap ukuze ikhokhele igesi kuzilayidi ze-GSN.
Njengamanje, umthetho olandelwayo we-Umbra usesesigabeni sokuhlolwa ku-Ropsten testnet.Ngokusho kukaBen DiFrancesco, bahlela ukuthuthukisa i-protocol ye-Umbra futhi maduzane bazokwethulwa ku-mainnet ye-Ethereum.Umsebenzi wabo oyinhloko uwukuqinisekisa ukuphepha kwenkontileka.Kubandakanya ukuphepha kwezimali zabasebenzisi.
