Lub blockchain yuav tsum muaj kev ruaj ntseg los xyuas kom meej tias cov neeg nyiag nkas lossis cov neeg siv tsis tau tso cai tsis nkag mus rau cov ntaub ntawv tseem ceeb lossis nyiag nyiaj hauv lub network.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias Blockchain thev naus laus zis muaj qee qhov tsis zoo, uas cov neeg siv siab phem rau kev ua txhaum cai siv.

Lub blockchain yog tsim los ntawm ntau lub blocks. Cov blocks no muaj cov ntaub ntawv hais txog kev hloov pauv hauv lub network. Txhua lub block muaj qhov chaw nyob tshwj xeeb rau kev txheeb xyuas qhov thaiv. Blockchain kev ruaj ntseg tseem tuaj yeem raug hu ua cov txheej txheem tswj kev pheej hmoo, uas yog lub hom phiaj kom ruaj ntseg kev lag luam thiab tag nrho lub network. Blockchain kev ruaj ntseg tau dhau los ua qhov kev txhawj xeeb tseem ceeb vim tias muaj kev vam khom ntawm blockchain networks.

Blockchain Security yog dab tsi?

Blockchain Security hais txog kev ntsuas los tiv thaiv kev ncaj ncees, tsis pub leej twg paub, thiab cov ntaub ntawv muaj nyob rau ntawm blockchain. Blockchain thev naus laus zis tuaj yeem ruaj ntseg thiab pob tshab sau cov kev lag luam hauv ib qho kev faib khoom lag luam. Qhov kev ruaj ntseg tiv thaiv lub network blockchain los ntawm kev nkag mus tsis raug cai, ua kom cov ntaub ntawv raug thiab hloov tsis tau thiab tiv thaiv kev tawm tsam xws li kev siv nyiaj ob npaug, Sybil tawm tsam, thiab 51% tawm tsam.

Ib qho ntawm cov yam ntxwv tseem ceeb ntawm kev ruaj ntseg blockchain yog siv cov txheej txheem cryptographic los xyuas kom meej cov ntaub ntawv. Qhov no suav nrog kev siv tus yuam sij rau pej xeem los txheeb xyuas tus kheej ntawm cov neeg siv thiab ua kom muaj txiaj ntsig ntawm kev hloov pauv. Tsis tas li ntawd, kev pom zoo cov txheej txheem xws li Pov Thawj Kev Ua Haujlwm (PoW) thiab Cov Ntawv Pov Thawj ntawm Stake (PoS) siv tau cov kev hloov pauv los ntawm kev faib tawm ntawm cov nodes es tsis yog tso siab rau lub hauv paus hauv paus.

Dab tsi yog qee qhov kev pheej hmoo ntawm kev nyab xeeb ntsib los ntawm Blockchain thev naus laus zis?

Txawm hais tias muaj kev tiv thaiv kev ruaj ntseg zoo tsim rau hauv blockchain thev naus laus zis, ntau qhov kev pheej hmoo yuav tsum tau hais los xyuas kom muaj kev nyab xeeb ntawm cov ntawv faib tawm no. Yog li kev ruaj ntseg yog qhov kev txhawj xeeb tseem ceeb hauv blockchain thev naus laus zis vim ntau lab ntawm kev hloov pauv yuav tsum tau lees paub los ntawm cov nodes hauv lub network. Cov kev pheej hmoo kev nyab xeeb tau hais hauv qab no:

Kev siv nyiaj ob npaug - Qhov no tshwm sim thaum tus neeg siv sim siv tib lub cuab tam digital ob zaug, ua rau muaj kev tsis sib haum xeeb hauv daim ntawv teev npe. Blockchain thev naus laus zis siv cov txheej txheem kev pom zoo los tiv thaiv hom kev tawm tsam no.

Sybil Attacks- Qhov no suav nrog cov neeg siv siab phem tsim ntau yam cuav lossis cov nodes kom tswj tau lub network. Tus neeg tawm tsam dej nyab lub network nrog kev khiav tsheb los ntawm kev tsim cov nodes cuav. Kev pom zoo mechanisms pab txo cov hom kev tawm tsam no.

51% Kev Tawm Tsam- Qhov no tshwm sim thaum ib lub koom haum tswj hwm ntau dua 50% ntawm lub network kev suav lub zog, tso cai rau lawv los tswj hwm lub blockchain.

Smart Contract Vulnerabilities- Cov ntawv cog lus ntse yog cov ntawv cog lus rau tus kheej uas khiav ntawm blockchain. Txawm li cas los xij, cov ntawv cog lus no tuaj yeem ua rau muaj kev tawm tsam yog tias tsis tsim thiab tshuaj xyuas zoo.

Malware Attacks- Malware tuaj yeem kis tus neeg siv lub khoos phis tawj lossis khoom siv thiab nkag mus rau lawv cov yuam sij ntiag tug, tso cai rau hackers nyiag lawv cov cuab tam digital.

Blockchain ua kom muaj kev ruaj ntseg hauv lub network li cas?

Txhawm rau kom muaj kev ruaj ntseg ntawm Blockchain, ntau qhov kev ntsuas tuaj yeem raug coj los tiv thaiv kev pheej hmoo tau teev tseg saum toj no. Qee txoj hauv kev zoo tshaj plaws los tiv thaiv blockchain kev ruaj ntseg suav nrog:

Ua raws li kev ruaj ntseg coding- Txhawm rau tiv thaiv qhov tsis zoo ntawm daim ntawv cog lus ntse, ua raws li kev tiv thaiv kev tiv thaiv kev nyab xeeb thiab kev soj ntsuam cov ntawv cog lus ntse yog qhov tseem ceeb.
Siv multi-factor authentication- Qhov kev lees paub no ua haujlwm raws li txheej txheej ntxiv ntawm kev ruaj ntseg thiab pab tiv thaiv kev tawm tsam uas sim nkag mus rau tus neeg siv tus yuam sij ntiag tug.
Cov txheej txheem Cryptographic- Public key encryption thiab hash functions yog siv los tiv thaiv blockchain. Tus yuam sij rau pej xeem yog siv los txheeb xyuas cov neeg siv khoom thiab xyuas kom muaj txiaj ntsig ntawm kev hloov pauv.
Kev Pom Zoo Cov Txheej Txheem- PoS thiab PoW yog siv los xyuas kom meej tias lub network ntawm nodes validates muas. PoW xav kom cov nodes los daws cov teeb meem kev ua lej nyuaj ntxiv rau qhov thaiv tshiab rau cov saw hlau. PoS xav kom cov nodes los koom nrog cryptocurrency kom siv tau cov kev hloov pauv.
Distributed Networking- Lub blockchain yog tsim los ua ib qho kev faib tawm ntawm cov nodes, txhais tau tias tsis muaj lub hauv paus tswj hwm. Qhov no txo qhov kev pheej hmoo ntawm ib qho kev ua tsis tiav thiab ua rau nws nyuaj rau cov neeg tawm tsam kom cuam tshuam lub network.
Siv cov firewalls thiab antivirus- Firewalls thiab antivirus software tuaj yeem pab tiv thaiv malware tawm tsam ntawm lub network.
Immutable ledger- Lub blockchain yog qhov hloov tsis tau, txhais tau hais tias ib zaug kev sib pauv tau sau tseg, nws tsis tuaj yeem hloov lossis tshem tawm. Qhov no ua kom paub tseeb tias daim ntawv teev npe yog tamper-proof.
Encrypting Cov ntaub ntawv- Cov ntaub ntawv khaws cia rau ntawm blockchain yuav tsum tau encrypted los tiv thaiv kev nkag mus tsis tau tso cai.
