Kuxelwe ukuba iprotocol ye-Umbra yaphuhliswa nguMat Solomon kunye noBen DiFrancesco kwi-HackMoney 2020 i-hackathon ebonakalayo, kwaye okwangoku ifumaneka kwi-Ethereum Ropsten testnet.
Isetyenziselwa ntoni?yithi nje:

"Ngedilesi engabonakaliyo, umhlawuli unokuthumela iithokheni ze-ETH okanye ze-ERC20 kwidilesi elawulwa ngumamkeli, kwaye ngaphandle kwamaqela omabini, akukho mntu wesithathu unokwazi ukuba ngubani umamkeli."

Kwikhonkco, ukuthengiselana kubonakala ngathi kudluliselwa kwidilesi engasetyenziswanga kwinethiwekhi ye-Ethereum.

Umzobo: Jonga ukuthengiselana kwe-ETH usebenzisa i-Umbra protocol kwi-Etherscan.Kwikhonkco, idilesi engabonakaliyo ibonakala njengedilesi ye-EOA eqhelekileyo.

Ngaphandle kwekhonkco, umthumeli usebenzise i-ENS ukuvelisa idilesi entsha ngeqhosha likawonke-wonke elikhutshwe ngumamkeli.Ngokubethela idatha esetyenziselwa ukuvelisa idilesi, kwaye ngokusebenzisa isivumelwano se-Umbra smart, umthumeli unokwazisa umamkeli ukuba uthumele intlawulo kwidilesi entsha engabonakaliyo.Ngumamkeli kuphela onokwenza isitshixo sabucala esifunekayo ukutsala imali.

Ngokusebenzisa inethiwekhi yesiKhululo seGesi kunye ne-Uniswap, i-Uniswap yenza ukuba ukurhoxiswa kusetyenziswe amathokheni abawafumanayo ukuhlawula igesi.Oku kuthintela isidingo sokusebenzisa i-ETH ukuxhasa ngemali iidilesi ezingabonakaliyo ngaphambi kokuhoxiswa kwemali.
Umahluko phakathi kwe-Umbra kunye neTornado Cash

Nguwuphi umahluko phakathi kwe-Umbra kunye neTornado Cash ehlala ichazwa nguVitalik?

Ngamafutshane, iTornado Cash ngumxube wengqekembe ekwi-chain esebenzisa ubungqina obungenalwazi.Xa ufaka iingqekembe kuyo kwaye ulindele abanye ukuba benze okufanayo, ungasebenzisa ubungqina bakho ukurhoxisa impahla.Igxininiswe kumxube, ngoko ikhonkco phakathi kwedilesi yomthombo kunye nedilesi yokuhoxiswa iphukile.

Iprotocol ye-Umbra isetyenziselwa intlawulo phakathi kwamaziko amabini, kwaye iza neseti eyahlukileyo yorhwebo lwabucala (oko kukuthi, iindlela ezahlukeneyo ziyaqwalaselwa).I-Umbra ayiphuli ikhonkco phakathi komthumeli kunye needilesi zomamkeli, kodwa yenza ukuba iiLinki zingabi nantsingiselo.Wonke umntu unokwazi idilesi apho imali ithunyelwa khona, kodwa abanakukwazi ukuba ngubani olawula loo dilesi.

Ukongeza kwezi, iprotocol ye-Umbra nayo ineempawu ezinomdla kakhulu.Umzekelo, isebenzisa irhasi encinci kakhulu kuba ayifuni nabuphi na ubuchwephesha obukwizinga eliphezulu lokuguqulela kwikhonkco lokuqinisekisa.Zonke iintengiselwano ludluliselo olulula.Ukongeza, ivumela i-ETH kunye naziphi na iimpawu ze-ERC20 ukuba zidluliselwe ngasese, awudingi ukuthembela kwisethi enkulu engaziwa.

Inkcazo yomgaqo wokusebenza we-Umbra protocol

Okokugqibela, thetha ngokufutshane malunga nendlela iprotocol ye-Umbra ephunyezwa ngayo:

Umsebenzisi uthumela umyalezo osayiniweyo kwirekhodi yombhalo we-ENS ukubonisa isitshixo sikawonke-wonke se-Umbra.Eli qhosha likawonke-wonke lithatyathwe kwiqhosha labucala elingenamkhethe elenzelwe ngokukodwa i-Umbra.
Umhlawuli usebenzisa eli qhosha likawonke-wonke, kunye nedatha eveliswe ngokungacwangciswanga, kwaye emva koko udala idilesi entsha "engabonakaliyo".
Umhlawuli usebenzisa isitshixo sikawonke-wonke somamkeli ukufihla idatha engacwangciswanga.
Umhlawuli uthumela imali kwidilesi ekhuselweyo kwaye athumele umyalezo ofihliweyo kwinkontileka ye-umbra ehlakaniphile.Ikhontrakthi isasaza umyalezo ofihliweyo njengomcimbi.
Umamkeli uhlola umyalezo ofihliweyo osasazwa yi-Umbra protocol de ifumane umyalezo onokuthi ucatshulwe ngeqhosha labucala.
Umamkeli usebenzisa umxholo womyalezo ofihliweyo kunye nesitshixo sabo sabucala ukuvelisa isitshixo sabucala sedilesi engabonakaliyo.
Ummkeli usebenzisa isitshixo sangasese sedilesi engabonakaliyo ukuba asayine ukuhoxiswa kwentengiselwano kwaye athumele i-ETH okanye ithokheni kwidilesi abayithandayo.
Enye enye indlela kukuba ukuhoxiswa kwentengiselwano isasazwa nge-Gas Station network transaction relayer, ukuphepha isidingo sokubonelela ngemali ye-ETH yokufikelela kwidilesi engabonakaliyo yethokheni.Ikhontrakthi ye-Umbra itshintshisa amathokheni athile nge-Uniswap ukuhlawula igesi kwi-GSN relayers.
Ukuza kuthi ga ngoku, iprotocol ye-Umbra isekwinqanaba lovavanyo kwi-Ropsten testnet.Ngokutsho kukaBen DiFrancesco, baceba ukuphucula i-protocol ye-Umbra kwaye kungekudala baya kuqaliswa kwi-mainnet ye-Ethereum.Umsebenzi wabo ophambili kukuqinisekisa ukhuseleko lwekhontrakthi.Ibandakanya ukhuseleko lweemali zabasebenzisi.
