I-Signal Technology Foundation, ethuthukisa isistimu yokuxhumana evikelekile Yesiginali, iqale kabusha ukushicilela ikhodi yezingxenye zeseva yesithunywa. Ikhodi yephrojekthi ekuqaleni yayivuliwe ngaphansi kwelayisensi ye-AGPLv3, kodwa ukushicilelwa kwezinguquko endaweni yokugcina umphakathi kwamiswa ngaphandle kwencazelo ngo-April 22 ngonyaka odlule. Isibuyekezo sekhosombe simile ngemva kokumenyezelwa kwenhloso yokuhlanganisa isistimu yokukhokha kusiginali.
Muva nje, siqale ukuhlola uhlelo lokukhokha olwakhelwe ku-Signal, ngokusekelwe ku-cryptocurrency yethu ye-MobileCoin (MOB), eyakhiwe ngu-Moxie Marlinspike, umbhali we-Signal protocol. Cishe ngaso leso sikhathi, izinguquko ezingxenyeni zeseva eziqoqwe phakathi nonyaka zanyatheliswa endaweni yokugcina, kuhlanganise nalezo ezihlanganisa ukuqaliswa kwesistimu yokukhokha.
I-MobileCoin cryptocurrency yakhelwe ukwakha inethiwekhi yokukhokha yeselula eqinisekisa ubumfihlo bomsebenzisi. Idatha yomsebenzisi isala ezandleni zabo kuphela futhi Onjiniyela Besiginali noma abalawuli bezinto zengqalasizinda abanalo ithuba lokufinyelela imali, idatha yebhalansi yomsebenzisi nomlando wokwenziwe. Inethiwekhi yokukhokha ayinalo iphuzu elilodwa lokulawula futhi isekelwe embonweni wobunikazi obabiwe, ingqikithi yawo ukuthi zonke izimali zenethiwekhi zakhiwe njengeqoqo lamasheya angawodwana angashintshwa. Isamba semali esiphelele kunethiwekhi simi ku-250 million MOB.
I-MobileCoin isekelwe ku-blockchain egcina umlando wazo zonke izinkokhelo eziphumelelayo. Ukuze uqinisekise ubunikazi bezimali, kufanele ube nokhiye ababili - ukhiye wokudlulisa izimali kanye nokhiye wokubuka isimo. Kubasebenzisi abaningi, lezi zikhiye zingathathwa kukhiye wesisekelo ojwayelekile. Ukuze uthole inkokhelo, umsebenzisi kufanele anikeze umthumeli okhiye ababili basesidlangalaleni abahambisana nokhiye abakhona abayimfihlo abasetshenziselwa ukuthumela nokuqinisekisa ubunikazi bezimali. Ukuthengiselana kukhiqizwa kukhompuyutha yomsebenzisi noma i-smartphone, ngemva kwalokho kudluliselwa kwenye yamanodi anesimo sokuqinisekisa ukuze kucutshungulwe endaweni engayodwa. Abaqinisekisi baqinisekisa ukuthengiselana futhi babelane ngolwazi mayelana nokuthengiselana namanye ama-node avela kunethiwekhi ye-MobileCoin ngokusebenzisa iketanga (ntanga kuya kontanga).
Idatha ingadluliselwa kuphela kuma-node aqinisekise ngokuyimfihlo ukusetshenziswa kwekhodi ye-MobileCoin engaguquki ku-enclave. I-enclave ngayinye engayodwa iphindaphinda umshini wombuso owengeza ukuthengiselana okuvumelekile ku-blockchain usebenzisa i-MobileCoin Consensus Protocol ukuze uqinisekise izinkokhelo. Ama-Node angakwazi futhi ukuthatha indima yokuba ngabaqinisekisi abagcwele, abakha futhi babambe ikhophi yomphakathi ye-blockchain ehlanganisiwe kumanethiwekhi okulethwa kokuqukethwe. I-blockchain ewumphumela ayinalo ulwazi oluvumela ukuhlonza umsebenzisi ngaphandle kokwazi okhiye bakhe. I-blockchain iqukethe kuphela izihlonzi ezibalwe ngokusekelwe kokhiye bomsebenzisi, idatha ebethelwe mayelana nezimali kanye nemethadatha yokulawula ubuqotho.
Ukuqinisekisa ubuqotho nokuvikela ekukhohlakaleni kwedatha ngemva kweqiniso, kusetshenziswa isakhiwo sesihlahla se-Merkle Tree, lapho igatsha ngalinye liqinisekisa wonke amagatsha namanodi angaphansi ngokusebenzisa i-hashing ehlangene (yesihlahla). Ukuba ne-hashi yokugcina, umsebenzisi angaqinisekisa ukunemba kwawo wonke umlando wokusebenza, kanye nokunemba kwezimo ezidlule ze-database (i-hashi yokuqinisekisa impande yesimo esisha se-database ibalwa ngokucabangela isimo esidlule. ).
Ngokungeziwe kuma-validators, inethiwekhi inamanodi e-Watcher, aqinisekisa amasignesha edijithali abaqinisekisi abanamathisela kubhulokhi ngayinye ku-blockchain. Ama-observer node ahlala eqapha ubuqotho benethiwekhi ehlukanisiwe, agcina awawo amakhophi endawo e-blockchain, futhi ahlinzeke ngama-API wezinhlelo zokusebenza ze-wallet kanye namakhasimende okushintshanisa. Noma ubani angakwazi ukusebenzisa i-validator kanye ne-node yokubuka; ngale njongo, izinsizakalo ezihambisanayo, izithombe ezihlanganisiwe ze-Intel SGX kanye ne-mobilecoind daemon ziyasatshalaliswa.
Umdali weSignal uchaze umqondo wokuhlanganisa imali ye-cryptocurrency esigijimini ngesifiso sokuhlinzeka abasebenzisi ngohlelo lokukhokha olusebenziseka kalula oluvikela ubumfihlo, olufana nendlela Isigijimi Esiyisignali esiqinisekisa ngayo ukuphepha kokuxhumana. UBruce Schneier, uchwepheshe owaziwayo emkhakheni we-cryptography nokuphepha kwekhompyutha, ugxeke izenzo zabathuthukisi beSiginali. U-Schneier ukholelwa ukuthi ukubeka wonke amaqanda akho kubhasikidi owodwa akusona isisombululo esingcono kakhulu, futhi iphuzu akukhona ukuthi kuholela ekuqhumeni nasekuxakekeni kohlelo, futhi ngisho nokuthi ukusetshenziswa kwe-blockchain kuyangabaza, hhayi ukuthi kuwumzamo. ukuhlanganisa Isignali ku-cryptocurrency eyodwa.
Inkinga eyinhloko, ngokusho kuka-Schneier, ukuthi ukwengeza uhlelo lokukhokha kuhlelo lokusebenza olubethelwe ekupheleni kuya ekupheleni kudala izinsongo ezengeziwe ezihambisana nenzalo eyengeziwe evela ezinhlanganweni ezihlukahlukene zezobunhloli kanye nabalawuli bakahulumeni. Ukuxhumana okuvikelekile kanye nokuthengiselana okuvikelekile kungenziwa kalula njengezinhlelo zokusebenza ezihlukene. Izinhlelo zokusebenza ezisebenzisa ukubethela okuqinile kokuphela ukuya ekupheleni sezivele ziyahlaselwa, futhi kuyingozi ukuqhubeka nokwandisa izinga lokuphikiswa - uma ukusebenza kuhlanganisiwe, umthelela ohlelweni lokukhokha uzohlanganisa ukusebenza kokubethela ngasemaphethelweni . Uma kufa ingxenye eyodwa, uhlelo lonke luyafa.
