I-Blockchain yembulwe: inguquko yezobuchwepheshe engafinyeleleka
I-Blockchain isezindebeni zawo wonke umuntu. Kodwa kuyini ngempela? Kungani kunesithakazelo esingaka kuwo? I-Institut Mines-Télécom, eqashelwa ubungcweti bayo, isinika ukuqeqeshwa ku-Coursera ukuze sinciphise lobu buchwepheshe obushintshayo.
Siqondiswa u-Romaric Ludinard, u-Hélène Le Bouder kanye no-Gaël Thomas, ochwepheshe abathathu abavelele kulo mkhakha, singena emhlabeni oyinkimbinkimbi we-blockchain. Basinikeza ukuqonda okucacile kwezinhlobo ezahlukene ze-blockchain: zomphakathi, ezizimele kanye ne-consortium. Ngayinye inezinzuzo zayo, imikhawulo kanye nezici zayo.
Kodwa ukuqeqeshwa akugcini lapho. Idlula ithiyori elula. Usiyisa emhlabeni wangempela we-blockchain, ehlanganisa izihloko ezifana ne-Bitcoin protocol. Isebenza kanjani ? Ikuqinisekisa kanjani ukuphepha kokwenziwe? Iyiphi indima edlalwa amasignesha edijithali nezihlahla ze-Merkle kule nqubo? Imibuzo eminingi ebalulekile lapho ukuqeqeshwa okuhlinzeka khona izimpendulo ezinolwazi.
Ngaphezu kwalokho, ukuqeqeshwa kugqamisa izindaba zomphakathi nezomnotho ezixhumene ne-blockchain. Ngabe lobu buchwepheshe buziguqula kanjani izimboni? Iwanikeza maphi amathuba amabhizinisi nakubantu ngabanye?
Lokhu kuqeqeshwa kuwuhambo lwengqondo lweqiniso. Ihloselwe wonke umuntu: abantu abanelukuluku lokwazi, ochwepheshe, abafundi. Inikeza ithuba eliyingqayizivele lokuqonda ngokujulile ubuchwepheshe obulolonga ikusasa lethu. Uma uke wafuna ukuqonda i-blockchain, manje yisikhathi. Qalisa le adventure ethokozisayo futhi uthole izimfihlo ze-blockchain.
Izindlela ze-cryptographic ze-blockchain: ukuphepha okuthuthukisiwe
I-Blockchain ivame ukuhlotshaniswa nombono wokuphepha. Kodwa lobu buchwepheshe bukwazi kanjani ukuqinisekisa ukwethembeka okunjalo? Impendulo ilele kakhulu ezindleleni ze-cryptographic ezisebenzisayo. Ukuqeqeshwa okunikezwa yi-Institut Mines-Télécom ku-Coursera kusiyisa enkabeni yalezi zindlela.
Kusukela kumaseshini okuqala, sithola ukubaluleka kwama-cryptographic hashes. Le misebenzi yezibalo iguqula idatha ibe uchungechunge lwezinhlamvu ezihlukile. Zibalulekile ekuqinisekiseni ubuqotho bolwazi ku-blockchain. Kodwa zisebenza kanjani? Futhi kungani zibaluleke kangaka ekulondekeni?
Ukuqeqeshwa akugcini lapho. Iphinde ihlole indima yobufakazi bomsebenzi enqubweni yokuqinisekisa okwenziwayo. Lobu bufakazi buqinisekisa ukuthi ulwazi olungezwe ku-blockchain lusemthethweni. Ngaleyo ndlela bavimbela noma yimiphi imizamo yokukhwabanisa noma yokukhohlisa.
Kodwa akugcini lapho. Ochwepheshe bayasiqondisa kumqondo wokuvumelana okusabalalisiwe. Indlela evumela bonke ababambiqhaza benethiwekhi ukuthi bavumelane ngobuqiniso bomsebenzi. Yilokhu kuvumelana okwenza i-blockchain ibe ubuchwepheshe obuhlukaniselwe futhi obusobala.
Ekugcineni, ukuqeqeshwa kubhekana nezinselelo zamanje ze-blockchain. Singakuqinisekisa kanjani ukugcinwa kuyimfihlo kwedatha kuyilapho siqinisekisa ukuba sobala kwayo? Ngokombono wokuziphatha, yiziphi izinkinga ezihlobene nokusetshenziswa kwalobu buchwepheshe?
Ngamafuphi, lokhu kuqeqeshwa kusinikeza ukubukeka okuthakazelisayo ngemuva kwezigcawu ze-blockchain. Kusivumela ukuthi siqonde ukuthi ikuqinisekisa kanjani ukuvikeleka nokuthembeka kolwazi oluqukethe. Ukuhlola okujabulisayo kwawo wonke umuntu ofuna ukujulisa ulwazi lwakhe ngalobu buchwepheshe.
I-Blockchain: okuningi kakhulu kunemali yedijithali
I-Blockchain. Igama elivusa ngokushesha i-Bitcoin kwabaningi. Kodwa ingabe yilokho kuphela okumele ukwazi? Kude lapho. Ukuqeqeshwa kwe-"Blockchain: izingqinamba nezindlela zokufihla i-Bitcoin" ku-Coursera kusigxilisa endaweni yonke enkulu kakhulu.
Bitcoin? Lesi yisihloko se-iceberg. Isicelo sokuqala sokukhonkolo se-blockchain, ngokuqinisekile, kodwa hhayi kuphela. Cabanga ngezwe lapho konke okwenziwayo, zonke izivumelwano, zonke izenzo zirekhodwa ngokusobala. Ngaphandle komlamuli. Ngokuqondile. Lesi isithembiso se-blockchain.
Thatha izinkontileka ezihlakaniphile. Izinkontileka ezisebenza ngokwazo. Ngaphandle kokungenelela komuntu. Bangayishintsha indlela esenza ngayo ibhizinisi. Yenza kube lula. Ukuze uvikeleke. Revolutionize.
Kodwa konke akulungile. Ukuqeqeshwa akugcini nje ngokuncoma ukufaneleka kwe-blockchain. Ubhekana nezinselelo zakhe. I-Scalability. Ukusebenza ngamandla. Umthethonqubo. Izinselelo ezinkulu okufanele zinqotshwe ukuthunyelwa kwenani elikhulu.
Nezinhlelo zokusebenza? Abanakubalwa. Ukusuka kwezezimali kuye kwezempilo. Kusukela ku-real estate kuya ku-logistics. I-Blockchain ingashintsha yonke into. Kwenze kucace kakhudlwana. Isebenza kahle kakhulu.
Lokhu kuqeqeshwa kuwumnyango ovulekile wekusasa. Ikusasa lapho i-blockchain izodlala indima emaphakathi. Lapho ingachaza kahle indlela yethu yokuphila, ukusebenza, ukuxhumana. Into eyodwa eqinisekile: i-blockchain ayinqunyelwe ku-Bitcoin. Uyikusasa. Futhi lelikusasa liyajabulisa.
