Ingabe i-blockchain iyi-inthanethi entsha?
Imidondoshiya kudala inentshisekelo kulobu buchwepheshe. I-Toyota, isibonelo, ihlose ukusebenzisa i-blockchain kuzixazululo ezihlobene nenethiwekhi yezimoto ezizimele. Ngisho ne-National Securities Depository yethu ifuna ukwethula isevisi ye-prototype ku-blockchain ekupheleni konyaka. Emhlabeni we-IT, konke sekuvele kwaziwa kahle. Sekuyisikhathi sokumethula kwabanye.
Igama lesiNgisi lisho "blockchain". Leli bekuyigama lencwadi ye-cryptocurrency transaction. Lokhu akuyona into engaphezu kwerejista yokuthengiselana kwezezimali. Ngakho-ke yini ekhangayo ngakho, izinkampani ezinkulu kanye nomhlaba wezezimali zicabangani ngakho? Impendulo: ukuphepha.
Igcina yonke imisebenzi eyenziwe kusukela ekuqaleni kohlelo. Ngakho, amabhulokhi kulolu chungechunge aqukethe ukuthengiselana okwenziwa abasebenzisi kunethiwekhi ye-cryptocurrency. Isihluthulelo sokuphepha kanye nokumelana okuphawulekayo nokugebenga silele eqinisweni lokuthi ibhulokhi ngayinye iqukethe ngaphakathi kwayo. i-checksum yebhulokhi yangaphambilini. Okufakiwe kulokhu kubhaliswa akukwazi ukushintshwa. Uma kuphela ngoba okuqukethwe kugcinwa kumakhophi yibo bonke abasebenzisi be-cryptocurrency abanesofthiwe yeklayenti efakwe kumakhompyutha abo.
ivulelwa kuphela ukuthengiselana okusha, ngakho-ke ukusebenza uma sekwenziwe kugcinwa kuyo unomphela, kuncane kakhulu noma akukho okwenzekayo kokwenza izinguquko kamuva. Umzamo wokushintsha ibhulokhi eyodwa uzoshintsha lonke iketango elilandelayo. Uma othile ezama ukukopela, ukulungisa okuthile, noma ukufaka ukuthengiselana okungagunyaziwe, ama-node, ngesikhathi senqubo yokuqinisekisa nokubuyisana, azothola ukuthi kukhona ukuthengiselana kwelinye lamakhophi ebhukwana elingahambisani nenethiwekhi futhi bayala ukubhala ngeketanga. Ubuchwepheshe busekelwe kunethiwekhi, ngaphandle kwamakhompyutha amaphakathi, amasistimu okulawula nokuqinisekisa. Noma iyiphi ikhompuyutha kunethiwekhi ingabamba iqhaza ekudlulisweni nasekuqinisekiseni ukuthengiselana.
Ingagcinwa kumabhulokhi edatha kunethiwekhi izinhlobo ezahlukene zokuthengiselanafuthi hhayi nje labo ababanjiwe. Uhlelo lungasetshenziswa, isibonelo, lwe imisebenzi yezentengiselwano, ukwaziswa, ukuhweba ngamasheya, ukuvikelwa kwemvelo ukukhiqiza amandla noma ku ukuthenga noma ukuthengisa imali yendabuko. Umsebenzi uyaqhubeka ukusebenzisa i-blockchain njenge-ledger in ebhange, Ukuqinisekisa Idokhumenti kanye Nohlelo Lwesiginesha Yedijithali ye-Electronic ekuphathweni komphakathi. Konke lokhu kuthengiselana kungenziwa ngaphandle kwezinhlelo ezaziwa iminyaka - ngaphandle kokubamba iqhaza kwezikhungo ze-state trust (isibonelo, ama-notaries), ngqo phakathi kwezinhlangothi zokuthengiselana.
Kulinganiselwa ukuthi ukwephula ama-cipher enethiwekhi ngokusekelwe ezindleleni zezibalo ezithuthukisiwe kanye nokuvikelwa kwe-cryptographic kuzodinga amandla ekhompyutha alingana nengxenye yazo zonke izinsiza ze-inthanethi. Kodwa-ke, abanye bakholelwa ukuthi ukwethulwa kwesikhathi esizayo kwamakhompiyutha e-quantum kuzodinga ukwethulwa kokuvikela okusha kwe-cryptographic.
Uchungechunge lwemisebenzi evikelekile
Ukugeleza kwezinkampani nemibono
Cishe iminyaka emithathu, izwe le-IT libone ukukhula kwangempela ezinkampanini ze-IT ezithuthukisa ukuphepha okusekelwe ekuvikelekeni kwe-crypto-currency technologies. Ngesikhathi esifanayo, sibona ukuzalwa kwemboni entsha, ebizwa ngokuthi (kusukela ekuhlanganiseni kwezezimali nobuchwepheshe), nasembonini yomshuwalense - (). Ngo-2015, kwasungulwa i-consortium yamabhange nezinkampani ukuze kuthuthukiswe. Ubulungu bayo buhlanganisa amakhulu kunawo wonke, okuhlanganisa iCitibank, Bank of America, Morgan Stanley, Société Générale, Deutsche Bank, HSBC, Barclays, Credit Suisse, Goldman Sachs, JP Morgan kanye ne-ING. NgoJulayi odlule, i-Citibank yaze yamemezela ukuthi isungule i-cryptocurrency yayo ebizwa ngokuthi i-Citicoin.
Ubuchwepheshe buheha hhayi umkhakha wezezimali kuphela. Isixazululo silungele ukuxazulula ukuthengiselana kokuthengwa kwamandla nokudayiswa phakathi kwabakhiqizi abancane kumodeli yokuhlanganisa encane, isibonelo, phakathi kwemizi ekhiqiza ugesi kanye nabathengi bawo, nayo ehlakaziwe, njengezimoto zikagesi.
Izicelo ezingaba khona zezixazululo ze-blockchain zihlanganisa ukukhokha Oraz imali mboleko phakathi kwabantu kumasayithi akhethekile, ngaphandle kwabalamuli, isibonelo, ku-Abra, BTC Jam. Enye indawo I-inthanethi yezinto - isibonelo, ukulandelela isimo, umlando, noma ukwabelana komcimbi. Isixazululo singabuye sibe usizo ezenzweni izinhlelo zokuvota, mhlawumbe ngisho nasokhethweni nasezinhlolovo esikhathini esizayo - inikeza isibalo samavoti esizenzakalelayo esabalalisiwe esinomlando ophelele.
W ezokuthutha ingasiza ekuthuthukiseni izinhlelo zesimanje zokuqasha, ukwabelana ngohambo kanye nokuthutha abantu nempahla. Bangaphinde bahlakazwe futhi baphephe ngokuphelele ngenxa yalokho. izinhlelo zokuhlonza abantu, amasignesha edijithali nokugunyazwa. Okunye okungenzeka isitolo sedatha ezinhlelweni ezithenjwayo, ezisatshalaliswayo, ezimelana nokwehluleka kanye nemizamo yokuba nomthelela ekuthembekeni kwedatha.
Ilogo yohlelo lweNhlangano Yezizwe kanye nenethiwekhi ye-blockchain
Ukuhlaziywa kwe-Australia kanye nosizo lwe-UN
Kunamazwe nezinhlangano ezikhombisa intshisekelo enkulu kwezobuchwepheshe. inkundla yenethiwekhi yesikhathi esizayo. Isikhungo sikahulumeni wase-Australia i-Commonwealth Scientific and Industrial Research Organisation ishicilele imibiko emibili ngalesi sihloko ngoJuni 2017. Ababhali babo bahlaziya ubungozi namathuba okusetshenziswa e-Australia.
Ucwaningo lokuqala luveza izimo ezine ezingaba khona zokuthuthukiswa kobuchwepheshe beleja yedijithali esabalaliswe e-Australia kuze kube ngu-2030. Lezi zinketho zombili nethemba - kucatshangelwa izinguquko ohlelweni lwezezimali nezomnotho, kanye ongenathemba - isibikezelo sokuwa kwephrojekthi. Umbiko wesibili, i-Risks and Benefits for Custom Systems and Contracts, uhlola izimo ezintathu zokusebenzisa ubuchwepheshe: njengochungechunge lokuhlinzekwa kwezolimo, ukubika kukahulumeni, kanye nokudluliswa kwemali kanye nezimali ezithunyelwa nge-elekthronikhi.
Emasontweni ambalwa ngaphambili, kwavela izindaba kwabezindaba ukuthi i-Australia izoqaphela imali egcwele kusukela ngoJulayi 1, njengoba iJapane yayenze kusukela ekuqaleni kuka-April.
Inhlanganiso ye United Nations, ngohlelo lwe World Food Programme (WFP), ikhangela indlela ezintsha zokulwisana lendlala lobubha ikakhulu emazweni asathuthukayo. Omunye wabo kufanele abe. NgoMashi, i-UN yakhipha umbiko othi lolu hlelo beluhlolwa ePakistan kusukela ngoJanuwari. Baphela ngempumelelo, ngakho ngo-May i-UN yaqala ukusabalalisa usizo lobuntu eJordani eMpumalanga Ephakathi. Ilinganiselwa ku-10 abantu abangase bathole usizo esigabeni sokuqala. abaswele, futhi ngokuzayo kuhlelwe ukuthi kwandiswe ukufakwa kwalolu hlelo kubantu abayizinkulungwane eziyi-100.
Ukusetshenziswa kuzokwenza kube ngcono ukuphatha ukudla i izinsiza zezimalikanye nokuwahlukanisa ngaphandle kokungahambi kahle. Ngaphezu kwalokho, abahlomuli ngeke badinge i-smartphone noma izikhwama zephepha, okungenzeka bangabi nazo ngenxa yobumpofu. Abantu bazokhonjwa kusetshenziswa imishini yokuskena ye-retinal enikezwe i-IrisGuard eseLondon.
I-WFP ifuna ukusebenzisa lobu buchwepheshe kuzo zonke izifunda. Ekugcineni, le ndlela yokukhokha izonwetshwa emazweni angaphezu kwamashumi ayisishiyagalombili ezinhlelo ze-WFP. iba yindlela yokuhlinzeka izindawo ezimpofu kakhulu ngokuziphilisa njengemali noma ukudla. Kuphinde kube yindlela yokusheshisa usizo ezindaweni okunzima ukufinyelela kuzo.
Kubukeka sengathi ingaguqula cishe yonke indawo yempilo nobuchwepheshe. Kukhona nemibono yokuthi lena inkundla ezosivumela ukuthi sakhe i-inthanethi entsha ngokuphelele, ephephile, eyimfihlo futhi egxile kuzintshisakalo zabasebenzisi. Kunalokho, ngokwezinye izilinganiso, ubuchwepheshe bungase bube uhlobo lwe-Linux entsha - enye indlela, kodwa hhayi inkundla yokuxhumana "ejwayelekile".
Isithombe:
- Toyota kunethiwekhi evikelekile
- Uchungechunge lwemisebenzi evikelekile
- Uhlelo lwe-UN kanye nelogo yenethiwekhi
