Taw qhia
Mining yog cov txheej txheem ntawm kev ntxiv cov ntaub ntawv sib pauv rau Bitcoin cov ntaub ntawv pej xeem ntawm kev ua lag luam yav dhau los. Daim ntawv teev npe ntawm kev ua lag luam yav dhau los yog hu uablockchainraws li nws yog ib tug saw ntawmthaiv. Covblockchainua hauj lwm raupaub meejpauv mus rau lwm lub network raws li tau tshwm sim. Bitcoin nodes siv cov saw hlau thaiv kom paub qhov txawv ntawm Bitcoin kev lag luam raug cai los ntawm kev sim rov siv nyiaj npib uas twb tau siv rau lwm qhov.
Mining yog txhob txwm tsim kom muaj peev xwm siv tau thiab nyuaj kom muaj pes tsawg lub blocks pom txhua hnub los ntawm cov miners tseem nyob ruaj khov. Cov blocks tus kheej yuav tsum muaj cov ntaub ntawv pov thawj ntawm kev ua haujlwm kom pom tau tias siv tau. Cov ntaub ntawv pov thawj ntawm kev ua haujlwm no raug txheeb xyuas los ntawm lwm tus Bitcoin nodes txhua zaus lawv tau txais ib qho thaiv. Bitcoin siv covhashcashpov thawj-ntawm-kev ua haujlwm.
Lub hom phiaj tseem ceeb ntawm kev tsuas yog tso cai rau Bitcoin nodes mus txog qhov kev pom zoo ruaj ntseg, tamper-resistant. Mining kuj yog lub tshuab siv los qhia Bitcoins rau hauv cov kab ke: Miners tau them cov nqi sib pauv nrog rau "kev pab" ntawm cov nyiaj npib tshiab. Qhov no ob qho tib si ua haujlwm rau lub hom phiaj ntawm kev tshaj tawm cov nyiaj npib tshiab nyob rau hauv ib qho kev faib tawm nrog rau kev txhawb nqa tib neeg los muab kev ruaj ntseg rau lub kaw lus.
Bitcoin mining yog li hu ua vim nws zoo li cov mining ntawm lwm cov khoom lag luam: nws yuav tsum tau siv zog thiab nws maj mam ua rau cov chav tshiab muaj rau txhua tus neeg uas xav koom nrog. Ib qho tseem ceeb sib txawv yog tias cov khoom siv tsis yog nyob ntawm tus nqi ntawm cov mining. Feem ntau hloov tag nrho miner hashpower tsis hloov pes tsawg bitcoins raug tsim nyob rau lub sij hawm ntev.

Qhov Teebmeem-Kev Nyuaj Siab
Kev khawb ib lub thaiv yog qhov nyuaj vim tias SHA-256 hash ntawm lub block lub taub hau yuav tsum qis dua lossis sib npaug rau lub hom phiaj txhawm rau kom lub thaiv tau txais los ntawm lub network. Qhov teeb meem no tuaj yeem yooj yim rau kev piav qhia: Lub hash ntawm ib qho thaiv yuav tsum pib nrog qee tus lej ntawm xoom. Qhov tshwm sim ntawm kev suav tus hash uas pib nrog ntau xoom yog tsawg heev, yog li yuav tsum tau ua ntau yam kev sim. Txhawm rau tsim kom muaj tus hash tshiab txhua lub voj voog, ancoyog incremented. SaibPov thawj ntawm kev ua haujlwmyog xav paub ntxiv.
Kev ntsuas qhov nyuaj
Covnyuajyog qhov kev ntsuas ntawm qhov nyuaj npaum li cas los nrhiav qhov thaiv tshiab piv rau qhov yooj yim tshaj plaws uas nws tuaj yeem ua tau. Nws raug suav rov qab txhua xyoo 2016 blocks rau tus nqi xws li yav dhau los 2016 blocks yuav tau tsim nyob rau hauv raws nraim ob lub lis piam tau txhua leej txhua tus tau mining ntawm qhov nyuaj no. Qhov no yuav tawm los, qhov nruab nrab, ib qho thaiv txhua kaum feeb. Raws li ntau miners koom, tus nqi ntawm block creation nce. Raws li tus nqi ntawm block tiam nce, qhov nyuaj nce mus rau kev them nyiaj, uas muaj qhov sib npaug ntawm cov txiaj ntsig vim txo tus nqi ntawm block-creation. Txhua qhov blocks tso tawm los ntawm cov miners siab phem uas tsis ua raws li qhov xav taunyuaj phiajyuav tsuas yog tsis lees paub los ntawm lwm tus neeg koom hauv lub network.
Khoom plig
Thaum ib qho thaiv tau pom, tus neeg nrhiav pom tuaj yeem muab lawv tus kheej qee tus lej ntawm bitcoins, uas tau pom zoo los ntawm txhua tus neeg hauv lub network. Tam sim no qhov txiaj ntsig no yog 6.25 bitcoins; tus nqi no yuav ib nrab txhua txhua 210,000 blocks. SaibTswj Nyiaj Txiag.
Tsis tas li ntawd, tus miner tau txais cov nqi them los ntawm cov neeg siv xa cov kev hloov pauv. Tus nqi yog ib qho kev txhawb siab rau cov miner kom suav nrog kev sib pauv hauv lawv qhov thaiv. Nyob rau hauv lub neej yav tom ntej, raws li tus naj npawb ntawm cov tshiab bitcoins miners raug tso cai los tsim nyob rau hauv txhua lub block dwindles, cov nqi yuav ua rau ib tug ntau npaum li cas tseem ceeb feem pua ntawm cov nyiaj tau los tsuas.
