Dab tsi yog Ethereum Rollups? Ib qho kev daws teeb meem los txiav cov nqi lag luam

Txawm tias tom qab tus qhov tseeb crypto tsoo, Ethereum tseem kim rau ntau siv. Qhov ntawd yog vim Ethereum blockchain qeeb thiab tau ua tiav nws lub peev xwm. Tam sim no koj yuav tsum tau them nyiaj los ntawm lub qhov ntswg rau txhua qhov ntxiv ntawm qhov thaiv qhov chaw yog tias koj yuav tsum yuav tom ntej "yuav tsum-muaj" NFT. 

Txog thaum "Ethereum hwm 2.0, ” tiam tom ntej ntawm Ethereum blockchain, daws tag nrho cov teeb meem no, cov zej zog yuav tsum vam khom lub npe hu ua kev daws teeb meem: thev naus laus zis uas ua kom Ethereum blockchain. Scaling kev daws teeb meem txawv, tab sis feem ntau hais txog ib feem ntawm kev sib pauv ntawm lwm lub network - ib qho sai dua thiab pheej yig dua Ethereum - ua ntej muab cov saw tseem ceeb Ethereum nrog cov ntaub ntawv hais txog kev hloov pauv uas nws npaj yuav xa.

Dab tsi yog rollups?

Rollups yog ib qho kev daws teeb meem zoo li no. Lawv koom nrog dov li (li no lub npe) collections ntawm muas. Qhov kawg, dov-up pauv tau nthuav tawm rau Ethereum blockchain ua ib qho kev sib pauv. 

Rollups txiav cov nqi: tus nqi ntawm Ethereum kev lag luam, ntxiv rau tus nqi me me ntawm dov li cov khoom lag luam, tau sib cais ntawm cov neeg siv. Lawv kuj ua kom nrawm dua: qhov kev sib tw ua tau nrawm heev thiab Ethereum blockchain xav tau tsuas yog ua cov kev lag luam ib zaug xwb tsis yog ntau. Qhov ntawd yog qhov tseem ceeb thaum Ethereum maxes tawm ntawm ib ncig 15 kev lag luam toj ib ob tsis pab. 

Vitalik Buterin, Ethereum tus co-founder, xav tias scaling kev daws teeb meem zoo li rollups yuav txuas ntxiv ua lub luag haujlwm tseem ceeb ntawm blockchain txawm tias tom qab kev siv Ethereum 2.0. (Ceeb Toom: Ethereum Foundation txij li thaum tau tso tseg 2.0 lossis xa mus rau lub network kev txav mus rau cov pov thawj ntawm ceg txheem ntseeg thiab kev saws me nyuam ntawm shard chains.)

Cov rollups ua haujlwm li cas?

Muaj ob yam tseem ceeb ntawm rollups: optimistic rollups thiab xoom-knowledge rollups.

Muaj tswv yim zoo ua rau qhov kev xav tias tag nrho cov ntaub ntawv no dov tawm yog siv tau, thiab tsis muaj leej twg tab tom sim dag lub blockchain los ntawm kev zais cov kev lag luam spurious hauv rollups. Lub tswv yim yog tias los ntawm kev xav tias siv tau, txhua yam nrawm. Txhawm rau tiv thaiv kev dag ntxias kev lag luam, cov txheej txheem ua kom zoo tshaj plaws tso cai rau tib neeg los sib tw kev lag luam bunk. Qhov kev dag ntxias raug xa ncaj qha rau ntawm Ethereum network los xyuas seb nws puas raug cai, thiab daws qhov kev tsis sib haum xeeb. Ob tog muaj ETH koom nrog thiab yuav poob nyiaj yog tias lawv tsis raug lossis dag. 

Zero-knowledge rollups (tseem hu ua zk-rollups) ua haujlwm txawv heev. Lawv tso siab rau ib daim ntawv pov thawj hu ua xoom-paub pov thawj, uas tso cai rau ib tus neeg ua lej ua pov thawj tias cov lus muaj tseeb (uas ib tus neeg yog, hais, Greek) yam tsis tau nthuav tawm cov ntaub ntawv ntxiv txog cov nqe lus ntawd (xws li daim ntawv hla tebchaws). Nyob rau hauv crypto, cov no yog hu ua zk-SNARKs, nyob rau hauv kev siv mus rau ib tug ntxiv daim ntaub ntawv ntawm cryptography hu ua "succinct non-interactive sib cav tswv yim ntawm kev paub." Txoj kev no hla dhau qhov kev daws teeb meem kev tsis sib haum xeeb uas muaj nyob rau hauv qhov zoo tshaj plaws rollups vim hais tias "SNARK" me ntsis tsuas yog tso cai rau cov khoom siv tau raug xa mus rau qhov kev sib tw.

Leej twg yog tus tsim rollups?

Optimistic rollups:

• optimism: pheej yig txheej-2 system rau Ethereum
• kev txiav txim: ib qho L2 raws tu qauv rau Ethereum
• Boba Network: tiam tom ntej ntawm OMG Network

Zero-knowledge rollups:

• Loopring: ib qho kev cai uas tseem muab kev sib pauv tsis muaj roj
• Immutable X: L2 raws tu qauv rau NFTs
• ZKSync: xoom-kev paub L2 rau Ethereum

Koj tuaj yeem yuav rollups li cas?

Koj tsis tuaj yeem "yuav" cov kev daws teeb meem, tab sis koj tuaj yeem nqis peev hauv tokens uas vam khom cov thev naus laus zis. Loopring thiab Boba yog cov piv txwv nrov ntawm rollup technologies. Koj tuaj yeem yuav lawv cov tokens ntawm Ethereum-based decentralized exchanges lossis ntawm kev sib pauv hauv nruab nrab. Tshawb xyuas cov chaw xws li CoinMarketCap lossis CoinGecko kom pom cov khw loj tshaj plaws.

Koj tseem tuaj yeem siv DeFi cov kev pabcuam thiab kev sib pauv tsim los ntawm cov txheej txheem-2 no los txiav cov nqi sib pauv. Loopring, piv txwv li, ua haujlwm nws tus kheej txheej-2 pauv, kuj hu ua Loopring. Nyob ntawd, koj tuaj yeem ua kom zoo dua ntawm tag nrho cov kev zoo siab ntawm kev siv thev naus laus zis: tsis muaj roj, kev lag luam sai sai rau ERC-20 npib.

Lub neej yav tom ntej ntawm rollups: lub tshuab rau cov hnub nyoog lossis Band-Aid rau qhov teeb meem daws tau?

Hauv lub sijhawm luv luv, kev sib ntaus sib tua yuav ua rau npau taws ntawm ob qho kev sib tw ntawm kev sib tw: kev cia siab thiab xoom-kev paub. Qee tus hais tias cov ntawv pov thawj xoom-paub yog qhov zoo tshaj vim tias lawv tsis xav tau kev daws teeb meem daws teeb meem.

Lub neej yav tom ntej ntawm kev sib tw mus ntev yog nyob ntawm seb yuav hloov kho li cas rau Ethereum lub mainnet lauj kaub tawm. Ethereum tuaj yeem muaj ib hnub dhau los ua nrawm heev uas cov kev sib tw yuav zoo li qhov tsis tsim nyog txhawb nqa mus rau xob laim-ceev blockchain. Hloov pauv, sib tw L1 blockchains, zoo li Solana thiab avalanche, tuaj yeem dhau los ua neeg nyiam uas lawv tau txais Ethereum nkaus. Yog tias feem ntau ntawm DeFi cov tsheb khiav mus rau qhov chaw ntawm blockchains uas tsis yog Ethereum, rollups yuav rov ua dua. 

Xwb, rollups tuaj yeem nce ntxiv yog tias Ethereum ua zog dua. Lawv tuaj yeem koom ua ke nrog kev hloov kho yav tom ntej kom Ethereum yooj yim dua thiab pheej yig dua los siv rau cov neeg coob coob.
