Hnov lo lus 'Blockchain' ib tug uas tsis paub txog cryptocurrencies yuav zoo li nws mus rau lub cev blocks lossis chains thaum qee cov neeg tsis paub txog cryptos yuav xav tias nws zoo ib yam li Bitcoin.
Raws li cov Blockchain tshawb fawb lub koom haum, blockchain yog qhov thib ob hauv internet. Nws tau hais tias thawj internet, uas yog qhov peb muaj tam sim no, yog 'internet ntawm cov ntaub ntawv' thaum blockchain, thib ob internet, yog 'internet ntawm tus nqi.'
Interestingly, tsis muaj leej twg paub tus neeg lossis cov neeg uas tsim lub blockchain. Thaum credit ntawm ob qho tib si Bitcoin thiab Blockchain tau muab rau Satoshi Nakamoto, lub npe tsuas yog lub npe pseudonym.
Dab tsi yog blockchain technology?
Lub blockchain yog cov ntaub ntawv digital ntawm cov ntaub ntawv uas tau teem rau hauv cov ntaub ntawv hu ua Blocks, uas tuaj yeem sawv cev rau hauv daim ntawv ntawm cov cuab tam digital.
Hauv cov ntsiab lus yooj yim, nws yog lub network ntawm cov khoos phis tawj uas qhia tib yam keeb kwm ntawm kev lag luam, xws li cov npe ntawm cov kev sib pauv tau tuav ntawm txhua lub khoos phis tawj, thiab txhua qhov kev sib pauv tau tso cai los ntawm txhua lub khoos phis tawj kom nws hloov kho nws tus kheej tas li.
Lub blockchain yog thev naus laus zis uas muaj zog cryptocurrencies zoo li Bitcoin, Ethereum, thiab lwm yam.
Ib lub network ntawm 'nodes' ua rau blockchain. Lub Node yog lub khoos phis tawj txuas nrog lub blockchain network siv tus neeg siv khoom ua haujlwm ntawm kev lees paub kev lag luam.
Keeb kwm ntawm blockchain thiab bitcoin
Blockchain yog thawj lub tswv yim los ntawm Satoshi Nakamoto hauv xyoo 2008 (Wikipedia). Xyoo tom ntej, nws raug tua raws li ib tug qhov tseem ceeb ntawm bitcoin, qhov twg nws tau siv los ua cov ntaub ntawv pej xeem rau txhua qhov kev lag luam hauv lub network. Cov lus thaiv thiab cov saw hlau tau siv sib cais hauv Satoshi Nakamoto thawj txoj haujlwm tab sis, los ntawm 2016, lawv thiaj li siv ib lo lus, blockchain.
Los ntawm daim ntawv thov ntawm blockchain technology rau bitcoin, nws tau los ua tus thawj cryptocurrency los daws qhov teeb meem ntawm kev siv nyiaj ob npaug yam tsis tas yuav tsum muaj kev ntseeg siab zoo li tus neeg thib peb hauv kev lag luam.
Thaum lub Yim Hli 2014, cov ntaub ntawv bitcoin blockchain uas muaj tag nrho cov kev lag luam uas tau tshwm sim hauv lub network yog 20GB (gigabyte), thiab thaum Lub Ib Hlis 2017, nws tau loj hlob mus rau 100GB loj.
Blockchain ua haujlwm li cas?
Lub blockchain zoo li daim ntawv nthuav qhia uas tau muab luam tawm ntau txhiab zaus hla lub network ntawm cov khoos phis tawj, thiab nws tau hloov kho tsis tu ncua.
Nws ua rau kev nkag siab tias tib txoj hauv kev los tiv thaiv cov ntaub ntawv tseem ceeb ntawm ob tog yog kev ntseeg siab rau lub hauv paus tswj hwm zoo li lub txhab nyiaj lossis tuam txhab credit card. Txawm li cas los xij, blockchain muaj cov thev naus laus zis uas ruaj ntseg khaws cov ntaub ntawv zoo li no tshem tawm lub hauv paus tswj hwm los ntawm lub kaw lus uas hais kom 'cov miners' ua qhov yog.
Cov miners khaws tag nrho cov ntaub ntawv ntawm kev sib pauv uas tau tshwm sim hauv lub network cryptocurrency hauv lub sijhawm teev tseg. Cov miners ces mus rau hauv qee yam kev sib tw uas tus yeej tau txiav txim siab los ntawm ob qhov xwm txheej.
i. Cov miner uas muaj qhov feem ntau version ntawm blockchain.
ii. Tus thawj miner uas ua tiav ib qho kev ua lej nyuaj.
Cov miner uas tshwm sim yeej tsim ib qho thaiv tshiab nrog txhua qhov kev hloov pauv tshiab. Lwm cov miners, nyob rau hauv lem, hloov kho lawv cov ntaub ntawv blockchain mus rau qhov tseeb version tsim los ntawm tus yeej thiab tus yeej ces tau txais nqi zog.
Qhov zoo ntawm blockchain technology
Cov ntawv cog lus ntse.
Cov no yog cov ntawv cog lus automated thiab ua tus kheej. Nws tsis xav tau tus neeg thib peb zoo li cov tsev txhab nyiaj ua haujlwm. Cov ntawv cog lus ua lawv tus kheej tom qab tag nrho cov lus pom zoo tau ua tiav.
Kev Ruaj Ntseg.
Blockchain siv cryptography thiab encodes qhov kev sib pauv hauv txoj hauv kev uas ib tus tsis tuaj yeem pom raws nraim li cas qhov kev sib pauv tau ua tiav tab sis tsuas yog paub tias kev sib pauv tiav.
Nce efficiency thiab ceev.
Los ntawm automation ntawm cov txheej txheem koom nrog hauv blockchain as opposed to the traditional way of storing ledgers of transactions, muas tau sai thiab ntau npaum.
Txo nqi.
Rau txhua qhov kev lag luam, kev txo nqi yog qhov tseem ceeb heev. Nrog blockchain, koj tsis tas yuav muaj ntau tus neeg thib peb los ua kev lees paub vim nws tsis muaj teeb meem yog tias koj tuaj yeem ntseeg koj tus khub lag luam, hloov pauv, koj tsuas yog yuav tsum ntseeg cov ntaub ntawv ntawm blockchain.
Disadvantages ntawm blockchain technology
khib nyiab.
Txhua lub node khiav lub blockchain thiaj li tswj kev pom zoo thoob plaws blockchain. Qhov no ua rau muaj kev zam txim siab, xoom downtime thiab tseem ua rau tag nrho cov ntaub ntawv khaws cia ntawm blockchain mus ib txhis tsis hloov pauv. Thaum txhua tus ntawm rov ua haujlwm, nws hlawv ntau lub sijhawm thiab hluav taws xob.
Network / ceev nqi.
Blockchain thev naus laus zis xav tau cov nodes los khiav, tab sis raws li ntau lub network tshiab, lawv tsis muaj tus naj npawb ntawm cov nodes uas yuav pab tau kom siv dav.
Qhov loj ntawm Block.
Txhua qhov kev hloov pauv ntxiv rau cov saw yuav nce qhov loj ntawm cov ntaub ntawv, raws li txhua qhov ntawm yuav tsum muaj cov saw hlau txhawm rau khiav.
Hard thiab mos Forks.
Thaum cov nodes hloov lawv cov software, muaj ib qho kev nyiam rau "khob" hauv cov saw hlau. Nodes ua haujlwm cov software tshiab yuav tsis lees txais tib yam kev hloov pauv raws li cov nodes ua haujlwm qub.
xaus
Lub blockchain yog cov ntaub ntawv faib tawm uas khaws cov ntaub ntawv nthuav dav thiab cov ntaub ntawv. Daim ntawv teev npe yog encoded thiab ruaj ntseg tiv thaiv nws tiv thaiv txhua yam kev cuam tshuam, kho dua, thiab tshem tawm.
Qhov tseem ceeb ntawm blockchain thev naus laus zis los ua lub zog ntawm cryptocurrencies tsis tuaj yeem cuam tshuam vim nws muaj ntau qhov zoo thiab nws tsuas yog yuav tau zoo dua yav tom ntej.
Kev sib xyaw ntawm kev lag luam, kev faib tawm ntawm cov ntaub ntawv hauv daim ntawv teev npe thiab cov blocks muab lub sijhawm zoo rau cryptocurrencies! Tab sis twv dab tsi? Blockchain kuj tseem tuaj yeem siv rau hauv txhua qhov kev lag luam ib sab cryptocurrencies, los ntawm lub khw muag khoom noj mus rau cov txheej txheem kev xaiv tsa mus rau kas fes ntau lawm thiab xa tawm. Tsuav yog muaj cov ntaub ntawv khaws cia, blockchain tseem muaj txiaj ntsig.
