I-Byzantine Fault Tolerance (BFT): I-Decentralized Trust

I-Cryptography nokuphepha ezinhlelweni ezihlukaniselwe amazwe sekuphenduke izihloko ezibalulekile enkathini yobuchwepheshe bolwazi. Kulo mongo, ukubekezelelana kwamaphutha e-Byzantine (BFT) kuye kwavela njengomqondo obalulekile wokuqinisekisa ubuqotho nokwethenjwa kumanethiwekhi ahlukaniswe, njengama-blockchains. Kulesi sihloko, sizohlola ukuthi kuyini ukubekezelelana kwamaphutha e-Byzantine, inkinga yojenene baseByzantine, ubudlelwano phakathi kwe-BFT ne-blockchain, izinhlobo zamaphutha aseByzantine, kanye nezinzuzo nokulinganiselwa kwalobu buchwepheshe.

Iyini i-Byzantine Fault Tolerance (BFT)?

I-Byzantine Fault Tolerance, noma i-BFT, iwumqondo wekhompuyutha osho ikhono lesistimu ehlukaniselwe ukumelana nokwehluleka nokuziphatha okunonya, okuqinisekisa ukuthi uhlelo lusebenza ngendlela ehambisanayo nethembekile ngisho nalapho kukhona ama-node noma abadlali abenza ngokungahambisani noma ngonya. Ngamanye amazwi, i-BFT igxile ekumelaneni nokwehluleka okungenasizathu noma ukuhlaselwa kwezitha ezinhlelweni ezisabalalisiwe.

Iyini Inkinga Yezikhulu ZaseByzantine?

Inkinga yojenene baseByzantium iyisimo esiyinkolelo-mbono esibonisa isidingo sokubekezelela amaphutha eByzantine. Ake sithi iqembu lojenene baseByzantium lizungeze idolobha lesitha futhi kufanele lixhumanise ukuhlasela kwalo noma ukuhlehla. Abanye ojenene bangase babe amambuka futhi bathumele imilayezo engamanga kwabanye ojenene. Inselele iwukuqinisekisa ukuthi ojenene abathembekile benza isinqumo ngazwi linye, ngisho noma abanye babo bengathembekile noma uma imiyalezo phakathi kwabo ilahleka noma iqondiswa. Ukubekezelelana kwamaphutha eByzantine kubhekana nale nkinga, okuvumela ojenene ukuba bafinyelele ukuvumelana okuthembekile endaweni engathembekile.

Ubudlelwano phakathi kweBFT neBlockchain

Ubuchwepheshe beBlockchain, obusetshenziswa kuma-cryptocurrencies njenge-Bitcoin ne-Ethereum, buyindlela evelele yokusebenzisa ukubekezelela amaphutha eByzantine. Kunethiwekhi ye-blockchain, ama-node abamba iqhaza kufanele avumelane ngesimo se-blockchain kanye nokuthengiselana okuvumelekile. Ukubekezelelana kwamaphutha e-Byzantine kuqinisekisa ukuthi noma ngabe amanye ama-node anonya noma anephutha, inethiwekhi isengafinyelela ukuvumelana futhi igcine ubuqotho bedatha egcinwe ku-blockchain.

Izinhlobo zamaphutha aseByzantine

Kunezinhlobo ezimbalwa zamaphutha aseByzantine okufanele i-BFT ibhekane nazo:

  1. Ukwehluleka kokweqiwa: Amanye ama-node angase angaphenduli noma afeze izibopho zawo.
  2. Ukwehluleka kwekhomishini:Ama-Node angathumela ulwazi olungalungile noma olunonya.
  3. Amaphutha okulibazisa:Ama-Node angase abambezele ukulethwa komlayezo ngenhloso noma ngokungenhloso.
  4. Ukuhluleka kokuhlukanisa:Inethiwekhi ingahlukaniswa ibe izingxenye ezinqanyuliwe, okwenza ukuxhumana kube nzima.

Izinzuzo kanye nemikhawulo ye-BFT

Ventajas: Ukulinganiselwa:
Ukwethenjwa Nokuphepha: I-BFT iqinisekisa izinga eliphezulu lokwethembana nokuphepha ezinhlelweni ezisabalalisiwe ngokumelana nokwehluleka nokuhlasela okunonya. Ubunkimbinkimbi: Ukuqaliswa kwe-BFT kungaba yinkimbinkimbi futhi kudinga izindleko eziphezulu zokubala.
Ukungaguquguquki: Izinhlelo ze-BFT zigcina ukuhambisana kwedatha, okubalulekile ezinhlelweni zezimali nezokuvota. Inombolo yabahlanganyeli: Ukubekezelela amaphutha kweByzantine kungaba inselele kakhulu njengoba inani lamanodi abamba iqhaza kunethiwekhi likhula.
Ukwehluka: I-BFT ingakaleka futhi isebenze kahle, iyenze ifanelekele izinhlelo ezikhulayo. Ukubambezeleka: I-BFT ingakhuphula ukubambezeleka kokwenza izinqumo ngenxa yesidingo sokusebenzisana phakathi kwamanodi.
