Qhov thib ob loj tshaj plaws blockchain Ethereum yog tam sim no lub lis piam deb ntawm kev sib koom ua ke ntev tos. Qhov kev hloov tshiab yuav los tom ntej no qhia txog kev hloov pauv tag nrho ntawm blockchain los ntawm kev ua pov thawj-ntawm-ua haujlwm (PoW) mus rau pov thawj-ntawm- ceg txheem ntseeg (PoS).

Nyob nruab nrab ntawm qhov kev zoo siab, tau muaj kev sib cav thiab kev xav ntawm qhov ua tau zoo thiab kev cuam tshuam txog kev sib koom ua ke yav tom ntej mus rau lub beacon saw.
Ib qho kev sib tham tshaj plaws ntawm qhov kev tshwm sim yog Replay nres. Hauv tsab xov xwm no, peb piav qhia qhov kev tawm tsam Replay txhais li cas thiab koj tuaj yeem ruaj ntseg koj NFTs li cas.
Replay nres yog dab tsi?
Ib qho kev tawm tsam Replay feem ntau hu ua txiv neej-hauv-tus-nruab nrab nres. Nws tshwm sim thaum tus neeg nyiag nkag lossis tus neeg ua phem ua phem zais cia sib txuas, cuam tshuam, thiab tweaks cov ntaub ntawv ntawm lub network ruaj ntseg kom cov ntaub ntawv / kev lag luam raug ncua lossis rov qab mus rau qhov cuam tshuam ntawm tus neeg pib.

Tom qab kev sib koom ua ke, yuav muaj ob txoj haujlwm ua haujlwm / cov ntawv theej ntawm Ethereum blockchain - thiab Ethereum PoS (cov saw tshiab) thiab Ethereum PoW (cov saw qub). Vim tias cov saw hlau sib cais, cov khoom muaj nqis ntawm Ethereum network tam sim no, suav nrog cov tokens uas tsis yog-fungible, yuav muab duplicated rau PoS saw. Qhov no txhais tau hais tias NFTs koj tam sim no tuav yuav raug muab luam tawm, uas yog li qhib txoj hauv kev ntawm Replay nres.
Yuav ua li cas?
Yog tias xav tias yuav yog tus qub Ethereum PoW vam meej nrog cov miners 'kev txhawb nqa thiab ChainID tshiab, kev hloov pauv los ntawm PoW saw tuaj yeem rov ua dua lossis rov ua dua tshiab ntawm Ethereum PoS blockchain tshiab, uas muaj kev pheej hmoo thiab tuaj yeem ua rau poob ntawm cov khoom muaj nqis.
"Yog tias koj xa 100 ETHPoW ntawm POW saw ntawm koj lub hnab nyiaj mus rau ib tus phooj ywg, ces koj tus phooj ywg tuaj yeem tshaj tawm tib yam kev lag luam hauv POS saw thiab xa nws tus kheej 100 thawj ETH rau nws tib lub hnab nyiaj," Defi kws txawj piav.
NFTs kuj tseem muaj kev cuam tshuam rau qhov kev tawm tsam no. Qhov kev hloov pauv ntawm qhov duplicated Nft ntawm Ethereum PoW tuaj yeem rov ua dua ntawm PoS saw, ua rau tus neeg ua phem phem tuaj yeem thov cov cuab tam tseem ceeb ntawm Ethereum PoS network. Replay tawm tsam ntawm Ethereum cov cuab tam tuaj yeem ua rau muaj kev puas tsuaj hauv kev lag luam crypto, txawm hais tias ntau tus kws tshaj lij xav tias qhov yuav muaj feem me me raws li kev kwv yees tias EthPoW yuav tsis muaj sia nyob ntev.
Qhov zoo tshaj plaws thawj koom ruam yuav txo koj qhov raug rau qhov kev tawm tsam yog tias koj tam sim no tuav Ethereum cuab tam.

- Tom qab kev sib koom ua ke, koj tuaj yeem hloov tag nrho cov cuab tam los ntawm lub hnab nyiaj "B" mus rau lub hnab nyiaj loj (A) rau PoS saw.
- Tom qab ntawd, hloov tag nrho cov cuab tam PoW los ntawm hnab nyiaj "B" mus rau "C," tom kawg dhau los ua koj lub hnab nyiaj tseem ceeb rau kev lag luam ntawm PoW saw.
Lub tswv yim yog kom tsis txhob muaj / siv cov cuab tam hauv ib lub hnab nyiaj.
Lwm qhov kev xaiv los tiv thaiv Replay tawm tsam yuav messing li kev sib pauv npe, uas tej zaum yuav yog kev.
