ISiseko seTekhnoloji yeSignali, ephuhlisa inkqubo yonxibelelwano olukhuselekileyo lweSignali, iphinde yaqala ukupapasha ikhowudi yeengxenye zeseva yomthunywa. Ikhowudi yeprojekthi ekuqaleni yayivuleleke phantsi kwelayisenisi ye-AGPLv3, kodwa ukupapashwa kweenguqu kwindawo yokugcina uluntu kwamiswa ngaphandle kwengcaciso ngo-Epreli wama-22 kulo nyaka uphelileyo. Uhlaziyo lwendawo yokugcina luyekile emva kokubhengezwa kwenjongo yokudibanisa inkqubo yentlawulo kwiSiginali.
Kutshanje, siqale ukuvavanya inkqubo yokuhlawula eyakhelwe kwiSiginali, esekelwe kwi-cryptocurrency yethu ye-MobileCoin (MOB), ephuhliswe nguMoxie Marlinspike, umbhali weSiginali yeSiginali. Ngexesha elifanayo, utshintsho kumacandelo e-server aqokelelwe ngaphezu konyaka apapashwa kwindawo yokugcina, kubandakanywa nezo zibandakanya ukuphunyezwa kwenkqubo yokuhlawula.
MobileCoin cryptocurrency yenzelwe ukwakha inethiwekhi yentlawulo yeselula eqinisekisa ubumfihlo bomsebenzisi. Idatha yomsebenzisi ihlala ezandleni zabo kuphela kwaye abaphuhlisi beSignali okanye abalawuli beziseko zeziseko abanalo ithuba lokufikelela kwimali, idatha yebhalansi yomsebenzisi kunye nembali yokuthengiselana. Inethiwekhi yentlawulo ayinayo indawo enye yokulawula kwaye isekelwe kwingcamango yobunini ekwabelwana ngayo, ingundoqo yokuba zonke iimali zenethiwekhi zenziwe njengengqokelela yezabelo zomntu ngamnye ezinokutshintshwa. Isixa-mali esipheleleyo semali kwi-network silungisiwe kwi-250 yezigidi ze-MOB.
I-MobileCoin isekelwe kwi-blockchain egcina imbali yazo zonke iintlawulo eziyimpumelelo. Ukuqinisekisa ubunini beemali, kufuneka ube nezitshixo ezimbini - isitshixo sokudlulisa imali kunye nesitshixo sokujonga imeko. Kubasebenzisi abaninzi, ezi zitshixo zinokuthathwa kwisitshixo esisisiseko esiqhelekileyo. Ukufumana intlawulo, umsebenzisi kufuneka anike umthumeli izitshixo ezimbini zoluntu ezihambelana nezitshixo zabucala ezikhoyo ezisetyenziselwa ukuthumela kunye nokuqinisekisa ubunini beemali. Iintengiselwano ziveliswa kwikhompyuter yomsebenzisi okanye i-smartphone, emva koko zidluliselwe kwenye yeendawo ezinobume bokuqinisekisa ukusetyenzwa kwi-enclave esecaleni. Abaqinisekisi baqinisekisa ukuthengiselana kunye nokwabelana ngolwazi malunga nokuthengiselana kunye nezinye iindawo ezivela kwinethiwekhi ye-MobileCoin ngekhonkco (oontanga ukuya koontanga).
Idatha inokudluliselwa kuphela kwiindawo eziye zaqinisekisa ukusetyenziswa kwekhowudi ye-MobileCoin engaguqukiyo kwi-enclave. Nganye enclave ekwanti replicates umatshini karhulumente wongeza iintengiselwano esebenzayo blockchain usebenzisa MobileCoin Consensus Protocol ukuqinisekisa iintlawulo. Ii-Nodes nazo zinokuthatha indima yokuqinisekisa ngokupheleleyo, eyongeza ifom kwaye ibambe ikopi kawonkewonke ye-blockchain edibeneyo kwiinethiwekhi zokuhanjiswa komxholo. I-blockchain enesiphumo ayinalo ulwazi oluvumela ukuchonga umsebenzisi ngaphandle kokwazi izitshixo zakhe. I-blockchain iqulethe kuphela izichazi ezibalwe ngokusekelwe kwizitshixo zomsebenzisi, idatha efihliweyo malunga neemali kunye nemethadatha yokulawula ingqibelelo.
Ukuqinisekisa imfezeko kunye nokukhusela kurhwaphilizo lwedatha emva kwenyani, kusetyenziswe isakhiwo somthi we-Merkle Tree, apho isebe ngalinye liqinisekisa onke amasebe angaphantsi kunye namaqhuqhuva ngokusebenzisa i-joint (tree) hashing. Ukuba ne-hash yokugqibela, umsebenzisi unokuqinisekisa ukuchaneka kwayo yonke imbali yokusebenza, kunye nokuchaneka kweemeko ezidlulileyo zesiseko sedatha (i-hash yokuqinisekisa ingcambu yesimo esitsha sesiseko sedatha ibalwa kuthathelwa ingqalelo imeko yangaphambili. ).
Ukongeza kwi-validators, inethwekhi nayo inama-nodes oMboni, aqinisekisa iisignesha zedijithali ukuba i-validators inamathele kwibhloko nganye kwi-blockchain. Iinodi zomkhangeli zihlala zibeke esweni ingqibelelo yothungelwano olunikezelweyo, zigcina ezazo iikopi zendawo zebhloko, kwaye zibonelele ngee-APIs zezicelo ze-wallet kunye nabathengi bokutshintshana. Nabani na unokuqhuba isingqinisiso kunye nokujonga indawo; ngenxa yale njongo, iinkonzo ezihambelanayo, imifanekiso enclave ye-Intel SGX kunye ne-mobilecoind daemon zisasazwa.
Umyili weSiginali uchaze umbono wokudibanisa i-cryptocurrency kwisithunywa kunye nomnqweno wokubonelela abasebenzisi ngenkqubo yokuhlawula ekulula ukuyisebenzisa ekhusela ubumfihlo, efana nendlela uMthunywa weSiginali aqinisekisa ngayo ukhuseleko lonxibelelwano. UBruce Schneier, ingcali eyaziwayo kwinkalo ye-cryptography kunye nokhuseleko lwekhompyutheni, ugxeke izenzo zabaphuhlisi beSignali. U-Schneier ukholelwa ukuba ukubeka onke amaqanda akho kwibhaskithi enye akusona sisombululo silungileyo, kwaye ingongoma ayikho into yokuba kukhokelela ekuqhumeni kunye nobunzima beprogram, kwaye kungekhona nokuba ukusetyenziswa kwe-blockchain kuyathandabuzeka, kwaye kungekhona ukuba ngumzamo. ukubopha Umqondiso kwi cryptocurrency enye.
Ingxaki ephambili, ngokutsho kukaSchneier, kukuba ukongeza inkqubo yentlawulo kwisicelo esifihliweyo sokugqibela kudala izoyikiso ezongezelelweyo ezinxulumene nenzala eyongeziweyo evela kwiiarhente ezahlukeneyo zobuntlola kunye nabalawuli bakarhulumente. Unxibelelwano olukhuselekileyo kunye neentengiselwano ezikhuselekileyo zinokuphunyezwa ngokulula njengezicelo ezahlukeneyo. Izicelo eziphumeza uguqulelo oluluqilima ekupheleni ukuya ekupheleni sele bephantsi kohlaselo, kwaye kuyingozi ukunyusa ngakumbi iqondo lokuchaswa - xa umsebenzi udityanisiwe, impembelelo kwinkqubo yentlawulo iya kubandakanya ukusebenza kwe-encryption ekupheleni ukuya ekupheleni. . Ukuba ilungu elinye liyafa, yonke inkqubo iyafa.
