A kev tshawb fawb ntawv luam tawm los ntawm Lub Tsev Kawm Qib Siab Hebrew hauv Ixayees cov ntaub ntawv tau tshawb pom "thawj pov thawj ntawm kev pom zoo-qib kev tawm tsam ntawm qhov loj cryptocurrency." Cov ntawv tam sim no tab tom tos cov neeg txheeb xyuas tab sis siv cov ntaub ntawv muaj nyob rau ntawm cov saw hlau thiab Ethereum qhib qhov codebase los lees paub nws cov lus xaus.
Ntawm nws qhov tseem ceeb, daim ntawv qhia txog qhov teeb meem uas cov miners tuaj yeem hloov lub sijhawm muaj feem cuam tshuam nrog cov mined block kom tsis txhob muaj teeb meem ntau ntxiv hauv lub network. On-chain cov ntaub ntawv tshwm sim los txhawb qhov kev thov raws li Aviv Yaish, ib tus ntawm cov ntawv sau ntawv, tau hais txog F2Pool cov ntawv teev sijhawm thaiv tau raug hloov pauv los txhim kho cov khoom plig.

Txiv ntxawm Tsim
Ethereum tau tswj hwm los ntawm kev ua pov thawj ntawm kev pom zoo ua haujlwm, uas yuav raug hloov mus rau cov pov thawj ntawm cov ceg txheem ntseeg lub Cuaj Hli no. Txawm li cas los xij, txog rau lub sijhawm no, lub network zoo li muaj kev cuam tshuam rau qhov kev tawm tsam uas tau txheeb xyuas los ntawm Hebrew University.
Qhov kev pom zoo-theem kev tawm tsam yog hu ua Tus Txiv Plig Tsim Kev Tawm Tsam hauv daim ntawv hauv kev siv rau "txiv ntxawm" blocks siv hauv kev siv. Blocks hauv Ethereum blockchain ua raws li cov ntaub ntawv teev tseg uas tau kuaj xyuas, faib, thiab txheeb xyuas thoob plaws hauv lub network. Txiv ntxawm blocks yog cov blocks siv tau uas tau raug tshem tawm ntawm cov saw tseem ceeb tab sis tseem tau txais khoom plig.
"Qhov kev tawm tsam tso cai rau tus neeg tawm tsam los hloov cov neeg sib tw lub ntsiab-chain blocks tom qab qhov tseeb nrog lub block ntawm nws tus kheej, yog li ua rau cov block hloov miner poob tag nrho cov nqi pauv rau cov kev lag luam uas muaj nyob rau hauv lub block, uas yuav raug txo los ntawm lub ntsiab. - chains."
Cov miners tuaj yeem teeb tsa lub sijhawm thaiv lub sijhawm nyob rau hauv "ib qho kev khi tsim nyog," feem ntau hauv ob peb feeb. Ib lub pas dej mining uas tau sau tseg hauv kev tshawb fawb yog F2Pool, uas "hauv ob xyoos dhau los, F2Pool tsis muaj ib qho thaiv ib zaug nrog lub sij hawm" uas phim qhov kev xav tau. F2Pool yog ib lub pas dej loj tshaj Ethereum ua haujlwm nrog tus hashrate ntawm 129 TH / s thiab tsim kwv yees li 1.5K ETH hauv cov khoom plig txhua hnub.
Daim ntawv tseem hais ntxiv tias F2Pool's "tus tsim tau tshaj tawm zoo heev Kev raug txim ntawm kev sib tw mining pas dej ua ke, liam lawv rau kev tawm tsam nws tus kheej lub pas dej mining" thaum, qhov tseeb, "F2Pool tab tom tawm tsam lwm lub pas dej mining."
Qhov cuam tshuam nyiaj txiag ntawm qhov kev tawm tsam tseem tsis tau raug txheeb xyuas, tab sis CryptoSlate tau hu Yaish uas tau hais rau peb,
"Rau txhua qhov ua tau zoo ntawm kev tawm tsam, F2Pool tau txais 14% ntau ntxiv los ntawm cov khoom plig thaiv, thiab ntxiv rau tau txais tag nrho cov nqi sib pauv uas muaj nyob hauv.
Tam sim no peb tab tom sim muab kev kwv yees rau ob qho ntawm koj cov lus nug uas siv cov ntaub ntawv tiag tiag, uas yuav tshaj tawm tam sim ntawd thaum peb muaj lawv! "
Lub Tsev Kawm Ntawv Hebrew muaj "kev kho pob zeb rau Ethereum raws tu qauv" thiab tsim ib thaj rau kev txiav txim siab. Yaish hais hauv a blog ncej tias cov ntaub ntawv tau "tau tshaj tawm lub luag haujlwm rau Ethereum Foundation" ua ntej tshaj tawm.
