Kukho iintlobo ezimbini zeefolokhwe ze-blockchain: iifolokhwe ezinzima kunye neefolokhwe ezithambileyo.Nangona amagama afanayo kunye nokusetyenziswa kokuphela okufanayo, iifolokhwe ezinzima kunye neefoloko ezithambileyo zihluke kakhulu.Phambi kokuba uchaze amagama athi "ifolokhwe enzima" kunye "nefolokhwe ethambileyo", chaza amagama athi "ukuhambelana phambili" kunye "nokuhambelana ngasemva"
indawo entsha kunye node endala
Ngexesha lenkqubo yokuphucula i-blockchain, ezinye iindawo ezintsha ziya kuphucula ikhowudi ye-blockchain.Nangona kunjalo, ezinye ii-node azifuni ukuphucula ikhowudi ye-blockchain kwaye ziqhubeke ziqhuba inguqulo yakudala yekhowudi ye-blockchain, ebizwa ngokuba yi-node endala.
Iifolokhwe ezinzima kunye neefolokhwe ezithambileyo
Ifolokhwe enzima: I-node endala ayikwazi ukuqaphela iibhloko eziveliswa yi-node entsha (i-node endala ayihambelani phambili kunye neebhloko eziveliswa yi-node entsha), okubangela ukuba ikhonkco lihlulwe ngokuthe ngqo libe ngamatyathanga amabini ahluke ngokupheleleyo, enye ikhonkco endala ( eqhuba imvelaphi Kukho inguqu endala yekhowudi ye-blockchain, eqhutywa yi-node endala), kwaye enye ikhonkco entsha (eqhuba inguqu entsha ephuculweyo yekhowudi yebhlokhi, eqhutywa yi-node entsha).
Ifolokhwe ethambileyo: Ii-nodes ezintsha kunye nezidala zihlala kunye, kodwa aziyi kuchaphazela uzinzo kunye nokusebenza kwenkqubo yonke.I-node endala iya kuhambelana ne-node entsha (i-node endala iya phambili iyahambelana neebhloko ezenziwe yi-node entsha), kodwa i-node entsha ayihambelani ne-node endala (oko kukuthi, i-node entsha ayibuyelanga ngasemva. iibhloko ezenziwe yi-node endala), ezi zimbini zisenokwabelana zikhona kwikhonkco.
Ukuyibeka ngokulula, ifolokhwe enzima ye-cryptocurrency yedijithali ithetha ukuba iinguqulelo ezindala kunye nezintsha azihambelani kunye kwaye kufuneka zihlulwe zibe ziibhloko ezimbini ezahlukeneyo.Kwiifolokhwe ezithambileyo, inguqu endala iyahambelana nenguqu entsha, kodwa inguqu entsha ayihambelani nenguqulo endala, ngoko kuya kuba nefoloko encinci, kodwa isenokuthi ibe phantsi kwe-blockchain efanayo.
Imizekelo yeefolokhwe ezinzima:
Ifolokhwe ye-Ethereum: Iprojekthi ye-DAO yiprojekthi yokuxhasa abantu abaninzi eqalwe yi-blockchain IoT inkampani i-Slock.it.Ikhutshwe ngokusesikweni ngoMeyi 2016. Ukususela ngoJuni waloo nyaka, iprojekthi ye-DAO inyuse ngaphezu kwe-160 yezigidi zeedola zaseMelika.Akuzange kuthathe ixesha elide ukuba iprojekthi ye-DAO ijoliswe ngabahlaseli.Ngenxa ye-lophole enkulu kwikhontrakthi ehlakaniphile, Iprojekthi ye-DAO idluliselwe ngexabiso lemarike ye-50 yezigidi ze-ether.
Ukuze ukubuyisela asethi abatyali-mali abaninzi kwaye bayeke ukuphakuzela, Vitalik Buterin, umseki Ethereum, ekugqibeleni ecetywayo ingcamango ifolokhwe nzima, yaye ekugqibeleni wagqiba ifolokhwe nzima block 1920000 of Ethereum ngokusebenzisa uninzi lwevoti yoluntu.Uqengqele umva yonke i-ether kuquka nempahla yehacker.Nokuba i-Ethereum ilukhuni ifolokhwe kumatyathanga amabini, kusekho abanye abantu abakholelwa kubume obungenakuguquguquka be-blockchain kwaye bahlale kwikhonkco lokuqala le-Ethereum Classic.
Ifolokhwe eHard Vs Soft Fork-Yeyiphi eNgcono?
Ngokusisiseko, ezi ntlobo zimbini zeefolokhwe ezikhankanywe ngasentla zisebenza ngeenjongo ezahlukeneyo.Iifolokhwe ezinzima eziphikisanayo zahlula uluntu, kodwa iifolokhwe ezinzima ezicwangcisiweyo zivumela isoftware ukuba iguqulwe ngokukhululekileyo ngemvume yomntu wonke.
Iifolokhwe ezithambileyo lolona khetho luthambileyo.Ngokubanzi, into onokuyenza ilinganiselwe ngakumbi kuba utshintsho lwakho olutsha alukwazi ukungqubana nemithetho emidala.Oko kuthethiweyo, ukuba uhlaziyo lwakho lunokwenziwa ngendlela ehlala ihambelana, awudingi kuba nexhala malunga nokuqhekeka kwenethiwekhi.
