Muaj ob hom blockchain diav rawg: tawv diav rawg thiab mos diav rawg.Txawm hais tias cov npe zoo sib xws thiab kev siv tib yam nkaus, cov diav rawg tawv thiab rab diav rawg sib txawv heev.Ua ntej piav qhia cov ntsiab lus ntawm "hloov diav rawg" thiab "muab diav rawg", piav qhia cov ntsiab lus ntawm "kev sib raug zoo rau pem hauv ntej" thiab "rov qab sib raug zoo"
tshiab node thiab qub node
Thaum lub sij hawm lub blockchain upgrade txheej txheem, ib co tshiab nodes yuav upgrade lub blockchain code.Txawm li cas los xij, qee cov nodes tsis kam hloov kho lub blockchain code thiab txuas ntxiv mus khiav cov qub qub version ntawm blockchain code, uas yog hu ua lub qub node.
Hard forks thiab soft forks
Khob diav rawg: Cov node qub tsis tuaj yeem paub txog cov blocks uas tsim los ntawm cov tshiab node (cov qub node tsis tuaj yeem sib haum nrog cov blocks tsim los ntawm cov node tshiab), uas ua rau cov saw txuas ncaj qha rau hauv ob txoj hlua sib txawv, ib qho yog cov saw qub ( khiav thawj Muaj ib qho qub version ntawm blockchain code, khiav los ntawm lub qub node), thiab ib tug yog ib tug tshiab saw (khiav lub upgraded version ntawm lub blockchain code, khiav los ntawm lub tshiab node).
Mos diav rawg: Cov nodes tshiab thiab qub coexist, tab sis yuav tsis cuam tshuam rau kev ruaj ntseg thiab kev ua tau zoo ntawm tag nrho cov kab ke.Cov node qub yuav sib haum nrog cov tshiab node (cov qub node yog pem hauv ntej sib haum nrog cov blocks generated los ntawm cov tshiab node), tab sis cov tshiab node tsis sib xws nrog lub qub node (uas yog, lub tshiab node tsis rov qab tau tshaj. cov blocks tsim los ntawm cov qub node), ob leeg tseem tuaj yeem sib koom muaj nyob rau ntawm cov saw hlau.
Txhawm rau muab nws yooj yim, qhov nyuaj nkhaus ntawm digital cryptocurrency txhais tau hais tias cov qub thiab tshiab versions tsis sib xws thiab yuav tsum tau muab faib ua ob qhov sib txawv blockchains.Rau cov diav rawg mos, cov qub version yog sib xws nrog cov tshiab version, tab sis cov tshiab version tsis sib xws nrog cov qub version, yog li ntawd yuav muaj ib tug me ntsis diav rawg, tab sis nws tseem yuav nyob rau hauv tib lub blockchain.
Piv txwv ntawm hard forks:
Ethereum diav rawg: Txoj haujlwm DAO yog ib txoj haujlwm pabcuam pejxeem pib los ntawm blockchain IoT tuam txhab Slock.it.Nws tau raug tso tawm thaum lub Tsib Hlis 2016. Raws li lub Rau Hli ntawm lub xyoo ntawd, DAO qhov project tau nce ntau dua 160 lab US dollars.Nws tsis siv sijhawm ntev rau DAO qhov project yuav raug tsom los ntawm hackers.Vim tias muaj qhov tsis txaus ntseeg loj hauv daim ntawv cog lus ntse, DAO qhov project tau pauv nrog tus nqi lag luam ntawm $ 50 lab hauv ether.
Txhawm rau kho cov cuab yeej cuab tam ntawm ntau tus tub ua lag luam thiab nres qhov kev ceeb toom, Vitalik Buterin, tus tsim ntawm Ethereum, thaum kawg tau npaj lub tswv yim ntawm kev sib tw nyuaj, thiab thaum kawg ua tiav qhov nyuaj ntawm qhov thaiv 1920000 ntawm Ethereum los ntawm kev pov npav feem ntau ntawm cov zej zog.Rolled rov qab tag nrho cov ether nrog rau cov neeg nyiag nkas muaj.Txawm hais tias Ethereum nyuaj forked rau hauv ob lub saw, tseem muaj qee cov neeg uas ntseeg hais tias nyob rau hauv qhov hloov tsis tau ntawm blockchain thiab nyob rau hauv thawj cov saw ntawm Ethereum Classic.
Hard Fork Vs Soft Fork - Qhov twg zoo dua?
Hauv paus, ob hom diav rawg tau hais los saum toj no ua haujlwm sib txawv.Kev sib cav sib ceg tawv tawv sib faib cov zej zog, tab sis cov phiaj xwm tawv tawv tau tso cai rau software hloov kho dawb nrog txhua tus neeg pom zoo.
Soft forks yog qhov kev xaiv softer.Feem ntau, qhov koj tuaj yeem ua tau ntau dua vim tias koj qhov kev hloov pauv tshiab tsis tuaj yeem cuam tshuam nrog cov cai qub.Qhov ntawd tau hais tias, yog tias koj qhov kev hloov tshiab tuaj yeem ua rau hauv txoj hauv kev uas tseem sib xws, koj tsis tas yuav txhawj xeeb txog kev sib cais ntawm lub network.
