I-Blockchain ityhilwe: inguqu yezobuchwepheshe ekufikeleleni
I-Blockchain isemilebeni yomntu wonke. Kodwa yintoni kanye kanye? Kutheni kukho umdla ongaka kuyo? I-Institut Mines-Télécom, evunyiweyo ngobuchule bayo, isinika uqeqesho kwi-Coursera ukuze singabinantsingiselo obu buchwephesha benguqu.
Sikhokelwa nguRomaric Ludinard, uHélène Le Bouder kunye noGaël Thomas, iingcali ezintathu ezibalaseleyo kulo msebenzi, singena kwihlabathi elintsonkothileyo le-blockchain. Basinika ukuqonda okucacileyo kweentlobo ezahlukeneyo ze-blockchain: uluntu, lwabucala kunye ne-consortium. Nganye ineengenelo zayo, imida kunye neenkcukacha zayo.
Kodwa uqeqesho alupheli apho. Ihamba ngaphaya kwethiyori elula. Usingenisa kwihlabathi lokwenyani le-blockchain, egubungela izihloko ezifana ne-Bitcoin protocol. Ingaba isebenza kanjani ? Iqinisekisa njani ukhuseleko lweentengiselwano? Yiyiphi indima edlalwa iisignitsha zedijithali kunye nemithi ye-Merkle kule nkqubo? Mininzi ke imibuzo ebalulekileyo apho uqeqesho lunika iimpendulo ezinolwazi.
Ukongezelela, uqeqesho lugxininisa imiba yentlalo kunye nezoqoqosho edibene ne-blockchain. Le teknoloji iwaguqula njani amashishini? Ngawaphi amathuba enika amashishini nakubantu ngabanye?
Olu qeqesho luhambo lokwenyani lwengqondo. Ijolise kuwo wonke umntu: abantu abanomdla, iingcali, abafundi. Inika ithuba elikhethekileyo lokuqonda ngokunzulu itekhnoloji ebumba ikamva lethu. Ukuba ukhe wafuna ukuqonda i-blockchain, ngoku lixesha. Qalisa kolu hambo lunomdla kwaye ufumane iimfihlo ze-blockchain.
Iindlela ze-cryptographic ze-blockchain: ukhuseleko oluphuculweyo
I-Blockchain ihlala idibaniswa nombono wokhuseleko. Kodwa le teknoloji ikwazi njani ukuqinisekisa ukuthembeka okunjalo? Impendulo ixhomekeke ubukhulu becala kwiindlela ezifihlakeleyo ezisebenzisayo. Uqeqesho olubonelelwa yi-Institute Mines-Télécom kwi-Coursera lusithatha luse entliziyweni yezi ndlela.
Ukususela kwiiseshoni zokuqala, sifumanisa ukubaluleka kwe-cryptographic hashes. Le misebenzi yemathematika iguqula idatha ibe luluhlu lwabalinganiswa abakhethekileyo. Zibalulekile ekuqinisekiseni ukuthembeka kolwazi kwi-blockchain. Kodwa zisebenza njani? Yaye kutheni zibaluleke kangaka nje kunqabiseko?
Uqeqesho alupheli apho. Ikwaphonononga indima yoBungqina boMsebenzi kwinkqubo yokuqinisekiswa kwentengiselwano. Obu bungqina buqinisekisa ukuba ulwazi olongeziweyo kwi-blockchain lusemthethweni. Ngaloo ndlela banqanda naliphi na ilinge lobuqhetseba okanye ukukhohlisa.
Kodwa akuphelelanga apho. Iingcali zisikhokela kwingcamango yokusasazwa kwemvumelwano. Indlela evumela bonke abathathi-nxaxheba bothungelwano ukuba bavumelane ngokunyaniseka kwentengiselwano. Yiyo le mvumelwano eyenza i-blockchain ibe yitekhnoloji ebekwe elubala kunye ne-decentralized.
Ekugqibeleni, uqeqesho lujongene nemingeni ye-blockchain yangoku. Singakuqinisekisa njani ukuba yimfihlo kwedatha ngelixa siqinisekisa ukungafihli? Ukusuka kwimbono yokuziphatha, yeyiphi imiba enxulumene nokusetyenziswa kobu buchwepheshe?
Ngamafutshane, olu qeqesho lusinika ukujonga okunomdla emva kwe-blockchain. Ivumela ukuba siqonde indlela eqinisekisa ngayo ukhuseleko kunye nokuthembeka kolwazi oluquletheyo. Uphononongo olunomdla kuye nabani na ofuna ukwenza nzulu ulwazi lwabo lobu buchwepheshe.
I-Blockchain: kakhulu ngakumbi kunemali yedijithali
I-Blockchain. Igama elikhupha i-Bitcoin ngokukhawuleza kwabaninzi. Kodwa ngaba kuphelele apho ukwaziyo? Kude nalapho. Uqeqesho lwe "Blockchain: imiba kunye neendlela ezifihlakeleyo zeBitcoin" kwiCoursera kusintywilisela kwindalo enkulu kakhulu.
Bitcoin? Le yincam ye-iceberg. Ukusetyenziswa kwekhonkrithi yokuqala ye-blockchain, ngokuqinisekileyo, kodwa kungekhona yodwa. Yiba nomfanekiso wehlabathi apho yonke intengiselwano, sonke isivumelwano, yonke into eyenziwayo irekhodwa ngokuphandle. Ngaphandle komlamli. Ngqo. Esi sisithembiso se-blockchain.
Thatha izivumelwano ezihlakaniphile. Iikhontrakthi ezisebenza ngokwazo. Ngaphandle kokungenelela komntu. Banokutshintsha indlela esenza ngayo ishishini. Yenza lula. Ukukhusela. Revolutionize.
Kodwa konke akulunganga. Uqeqesho aluncomi nje ukulunga kwe-blockchain. Uyayilungisa imingeni yakhe. Ukubaleka. Ukusebenza ngamandla. Ummiselo. Imiceli mngeni emikhulu ekufuneka yoyiswe kukusasazwa kwamanani amakhulu.
Kwaye iiapps? Azinakubalwa. Ukusuka kwimali ukuya kwimpilo. Ukusuka kwi-real estate ukuya kwi-logistics. I-Blockchain inokuguqula yonke into. Yenze icace ngakumbi. Ukusebenza ngakumbi.
Olu qeqesho ngumnyango ovulekileyo wekamva. Ikamva apho i-blockchain iya kudlala indima ephambili. Apho inokuthi ichaze kakuhle indlela yethu yokuphila, ukusebenza, nokunxibelelana. Inye into eqinisekileyo: i-blockchain ayiphelelanga kwi-Bitcoin. Ulikamva. Kwaye elikamva linika umdla.
