Tsis ntev los no cov ntaub ntawv tshawb fawb tau luam tawm uas tuaj yeem ua rau Ethereum miners muaj teeb meem. Israel-based Hebrew University tau luam tawm cov ntaub ntawv tshawb fawb uas suav nrog kev tshawb pom ntawm cov pov thawj thawj zaug txog kev pom zoo-qib tawm tsam ntawm Ethereum. Txawm li cas los xij, daim ntawv tshawb fawb tseem tsis tau txais kev tshuaj xyuas. Nws tau hais kom siv cov ntaub ntawv muaj nyob rau ntawm cov saw hlau thiab qhib qhov chaw codebase ntawm Ethereum network kom ncav cuag cov lus xaus.
Kev tshawb fawb muaj cov teeb meem ntawm nws lub hauv paus ib puag ncig Ethereum cov miners. Nws hais tias cov miners tuaj yeem coj cov kev hloov pauv hauv mined blocks timestamp thiab txoj kev no lawv tuaj yeem zam lub network nyuaj ntxiv. On-chain muaj cov ntaub ntawv tseem zoo li txhawb nqa cov lus thov hauv daim ntawv.
Ib tug ntawm cov tsim ntawm cov ntawv tshawb fawb - Aviv Yaish - sau tseg lub sij hawm ntawm F2Pool tau manually thiab hloov kho nrog lub hom phiaj ntawm kev txhim kho khoom plig rau lawv tus kheej. Nws yog tsim nyog sau cia tias lub Ethereum network siv cov ntaub ntawv pov thawj-ntawm-kev pom zoo ua haujlwm uas yuav sai sai no los hloov cov pov thawj-ntawm- ceg txheem ntseeg nyob rau lub Cuaj Hli xyoo no.
Qhov kev pom zoo-theem kev tawm tsam uas tau teev tseg hauv cov lus ceeb toom tau hais txog kev tawm tsam Tus Txiv Plig Tsim. Qhov no tau muab siv rau kev siv 'txiv ntxawm' blocks uas tau siv los ntawm miners rau kev siv lub network. Ethereum blockchain cov blocks yog cov ntaub ntawv khaws cia cov ntaub ntawv uas tau kuaj xyuas, txheeb xyuas, thiab faib thoob plaws hauv lub network.
Txiv ntxawm blocks hais hauv cov lus ceeb toom yog cov blocks uas tau hais kom tshem tawm ntawm lub mainnet, txawm li cas los xij, nws tseem tuaj yeem tau txais khoom plig. Daim ntawv tshaj tawm tau tshaj tawm tias qhov kev tawm tsam yog txhais tau tias tso cai rau tus neeg tawm tsam los hloov cov saw tseem ceeb ntawm nws cov neeg sib tw. Qhov no ua rau hloov cov miner ntawm cov blocks no poob tag nrho cov nqi sib pauv tau txais tom qab kev lees paub kev lag luam khaws cia hauv qhov thaiv.
Cov miners thoob plaws hauv lub network tuaj yeem teeb tsa lub sijhawm ntawm qhov thaiv tsis pub dhau ib qho kev txwv, uas poob nrog qhov sib txawv ntawm ob peb feeb. Ib qho ntawm cov pas dej no yog F2Pool uas tau pom hauv kev tshawb fawb. F2Pool tsis muaj txawm tias ib qho thaiv ib zaug uas tuaj yeem ua tau raws li qhov xav tau.
