Iyo Signal Technology Foundation, iyo inogadzira iyo Signal yakachengeteka yekutaurirana system, yatangazve kuburitsa kodhi yezvikamu zveseva zvemutumwa. Kodhi yepurojekiti iyi yakatanga kuvhurwa pasi perezinesi reAGPLv3, asi kuburitswa kweshanduko kunzvimbo yeruzhinji kwakamiswa pasina tsananguro muna Kubvumbi 22 gore rapfuura. Iyo repository update yakamira mushure mekuziviswa kwechinangwa chekubatanidza chirongwa chekubhadhara muSignal.
Munguva pfupi yapfuura, takatanga kuedza nzira yekubhadhara yakavakirwa mukati Chiratidzo, zvichibva pachedu MobileCoin (MOB) cryptocurrency, yakagadzirwa naMoxie Marlinspike, munyori weSignal protocol. Panenge panguva imwecheteyo, shanduko kuzvikamu zveseva zvakaunganidzwa pamusoro pegore zvakadhindwa mune repository, kusanganisira izvo zvaisanganisira kuisirwa nzira yekubhadhara.
MobileCoin cryptocurrency yakagadzirirwa kuvaka nharembozha yekubhadhara iyo inovimbisa kuvanzika kwevashandisi. Data yemushandisi inoramba iri mumaoko avo chete uye vanogadzira Signal kana vatariri vezvivakwa zvezvivakwa havana mukana wekuwana mari, mushandisi chiyero data uye nhoroondo yekutengeserana. Iyo network yekubhadhara haina kana imwe poindi yekutonga uye yakavakirwa papfungwa yekugovaniswa varidzi, musimboti wekuti mari yese yetiweki inoumbwa semuunganidzwa wemigove yega inogona kuchinjana. Mari yese pane network inotarwa pa250 miriyoni MOB.
MobileCoin yakavakirwa pa blockchain inochengeta nhoroondo yezvose zvakabudirira kubhadhara. Kuti usimbise muridzi wemari, unofanirwa kunge uine makiyi maviri - kiyi yekufambisa mari uye kiyi yekuona chimiro. Kune vazhinji vashandisi, makiyi aya anogona kutorwa kubva kune yakajairwa base kiyi. Kuti ugamuchire muripo, mushandisi anofanirwa kupa mutumiri makiyi maviri eruzhinji anoenderana nemakiyi epachivande aripo anoshandiswa kutumira uye kuona muridzi wemari. Kutengeserana kunogadzirwa pakombuta yemushandisi kana smartphone, mushure mezvo zvinoendeswa kune imwe yemanodhi ine chimiro chevagadziriso chekugadzirisa mune yakasarudzika enclave. Validators simbisa kutengeserana uye kugovana ruzivo nezve kutengeserana nedzimwe node kubva MobileCoin network kuburikidza neketani (vezera kune vezera).
Data inogona chete kutamisirwa nodes kuti cryptographically akasimbisa kushandiswa unmodified MobileCoin bumbiro iri enclave. Imwe neimwe yakasarudzika enclave inodzokorora muchina wehurumende unowedzera kutengeserana kunoshanda kune blockchain uchishandisa MobileCoin Consensus Protocol kusimbisa kubhadhara. Node dzinogona zvakare kutora chinzvimbo cheakazara mavhaidhi, ayo anowedzera kuumba uye kugamuchira yeruzhinji kopi yekombuta blockchain pane zvemukati zvekutumira network. Iyo blockchain inokonzeresa haina ruzivo runobvumira kuziva mushandisi usingazive makiyi ake. Iyo blockchain ine chete zviziviso zvakaverengerwa zvichienderana nemakiyi emushandisi, yakavharidzirwa data nezve mari uye metadata yekutonga kwekuvimbika.
Kuve nechokwadi chekutendeseka uye kudzivirira kubva kuhuori hwe data mushure mechokwadi, chimiro cheMerkle Tree muti chinoshandiswa, umo bazi rega rega rinosimbisa matavi ese ari pasi nemanodhi kuburikidza nekubatana (muti) hashing. Kuve nehashi yekupedzisira, mushandisi anogona kuona kurongeka kwenhoroondo yese yekushanda, pamwe nekurongeka kwenzvimbo dzakapfuura dzedhatabase (iyo midzi yekuongorora hashi yemamiriro matsva edhatabhesi inoverengerwa uchifunga nezve mamiriro apfuura. )
Pamusoro pezvigadziriso, network inewo maWatcher node, ayo anosimbisa masiginecha edhijitari anosungirirwa kune imwe neimwe block mu blockchain. Vacherechedzi node dzinogara dzichitarisisa kutendeseka kweiyo decentralized network, chengetedza yavo yega makopi enzvimbo ye blockchain, uye inopa APIs echikwama application uye kuchinjanisa vatengi. Chero ani zvake anogona kumhanyisa iyo inosimbisa uye yekucherechedza node; nechikonzero ichi, masevhisi anoenderana, enclave mifananidzo yeIntel SGX uye mobilecoind daemon inogoverwa.
Mugadziri weSignal akatsanangura iyo pfungwa yekubatanidza cryptocurrency mutumwa nechishuwo chekupa vashandisi nzira yekubhadhara iri nyore inochengetedza kuvanzika, yakafanana nemabatiro anoita Signal messenger kuchengetedzeka kwekutaurirana. Bruce Schneier, nyanzvi inozivikanwa mumunda wecryptography uye kuchengetedzwa kwekombuta, yakatsoropodza zviito zvevagadziri veSignal. Schneier anotenda kuti kuisa mazai ako ose mubhasiki imwe haisi iyo yakanakisisa yekugadzirisa, uye pfungwa yacho haisi iyo inotungamirira kukuputika uye kuoma kwepurogiramu, uye kwete kunyange kuti kushandiswa kwe blockchain kune mubvunzo, uye kwete kuti kuedza. kusungira Signal kune imwe cryptocurrency.
Dambudziko rakakosha, maererano naSchneier, nderekuti kuwedzera hurongwa hwekubhadhara kune yekupedzisira-kumagumo encrypted application kunogadzira kumwe kutyisidzira kwakabatana nekuwedzera kufarira kubva kune akasiyana masangano ehungwaru nevatongi vehurumende. Kukurukurirana kwakachengeteka uye kutengeserana kwakachengeteka kunogona kuitwa nyore nyore semashandisirwo akasiyana. Zvishandiso zvinoshandisa kusimba kwekupedzisira-kusvika-kumagumo kwave kutorwiswa, uye zvine njodzi kuenderera mberi nekuwedzera dhigirii rekupikisa - kana mashandiro acho asanganiswa, kukanganiswa kwehurongwa hwekubhadhara kunosanganisira kushanda kwekupedzisira-kusvika-kumagumo encryption. . Kana chikamu chimwe chete chikafa, hurongwa hwose hunofa.
