Muag ntawm non-fungible tokens (NFTs) mus txog cov ntaub ntawv $ 25 nphom hauv xyoo 2021. Txawm li cas los xij, cov cim qhia hauv cov ntaub ntawv ntawm kev loj hlob qeeb mus rau qhov kawg ntawm lub xyoo taw qhia txog kev txhawj xeeb. Rov qab tshaj tawm xov xwm tshaj tawm txog kev nyiag khoom, tub sab nyiag - thiab, tej zaum feem ntau nyuaj, kev dag ntxias - tsis tau pab.
Raws li cov Piv txwv li ntawm impersonation ntawm comic phau ntawv artist Derek Laufman qhia tau hais tias, ntau tus neeg tsim khoom tseem ceeb thiab cov neeg siv NFT tsis paub meej txog kev nyab xeeb thiab qhov tseeb uas lawv raug cuam tshuam thaum minting thiab muab kev saib xyuas rau NFTs. Tsis tas li ntawd, cov kev tsim digital txuas nrog NFT's, piv txwv li, kos duab, feem ntau khaws cia tawm ntawm cov saw thiab tsis tas yuav khaws cia rau hauv qhov chaw muaj zog.
Ob peb lub hlis dhau los, tag nrho NFTs ntawm Ethereum thiab Solana blockchains tau muab pov tseg thiab ua kom muaj raws li ib qho 19.5 Terabyte sau ntawm qhov txuas online. Lawv cov tswv tej zaum xav tias lawv cov NFTs nyob rau ntawm cov saw hlau thiab yog li ntawd tag nrho thiab muaj kev nyab xeeb. Txawm li cas los xij, hauv ntau qhov xwm txheej, tsuas yog cov ntaub ntawv metadata tau tuav ntawm cov saw hlau. Cov duab no feem ntau yog jpegs tuav ntawm tus qauv web2 servers, zoo li Amazon Web Services (AWS), lossis los ntawm cov chaw khaws cia xws li IPFS. Yog tias cov kev pabcuam no mus offline (raws li hauv case of AWS ntau zaus xyoo tas los), cov dluab hosted off-chain yuav ploj tag nrho.
Trusted Execution Environments (TEEs) yuav pab tau li cas
Hmoov zoo, kev daws teeb meem zoo rau kev khaws cia zoo, kev lees paub, thiab kev txheeb xyuas ntawm NFTs tam sim no muaj. Trusted execution ib puag ncig (TEEs) pab NFT cov neeg tawm tswv yim kom ua tiav cov cai hauv qhov chaw nyab xeeb thiab tsis muaj kev hloov kho, muab kev nyab xeeb siab. TEEs tau dhau qhov teeb meem ntawm cov neeg tsim khoom sib txawv tsim cov cai hauv ib puag ncig uas lawv tswj tsis tau tag nrho thiab qhov twg muaj ntau lwm qhov chaw ua haujlwm tib lub sijhawm. Lawv tso cai rau cov neeg ua si hauv ib puag ncig tsis quav ntsej txog kev hem thawj los ntawm "tsis paub" lwm tus vim tias TEE tau lees paub qhov muaj zog tshaj plaws ntawm kev sib cais uas muaj peev xwm niaj hnub no thiab yog li ua kom muaj kev ruaj ntseg siab tshaj plaws. Kev suav hauv TEE tsis tuaj yeem nkag mus tau los ntawm lwm txoj haujlwm - suav nrog kev ua haujlwm.
VERITIC muab NFT infrastructure, suav nrog TEE uas tuaj yeem siv los daws cov teeb meem kev lees paub NFT xws li yuam sij yuam kev lossis raug nyiag thiab ploj metadata. VERITIC's TEE yog qhov muaj zog heev rau kev tawm tsam. Nws tuaj yeem txwv kev nkag mus rau cov tib neeg nkaus xwb thiab Casper cov peev txheej tswj hwm qhov tseem ceeb ntxiv kev ruaj ntseg ntxiv rau NFTs.
Lub foob ntawm kev pom zoo rau NFTs
Qhov kev daws teeb meem TEE ua kom ntseeg tau tias cov cai raug ua tiav thiab cov tswv yim yog qhov tseeb thiab muab pov thawj tias tsis muaj lwm tus neeg koom nrog hauv minting. Qhov no muab 'lub foob kev pom zoo' rau NFT tus tsim uas tau minted hauv TEE raws li lawv tuaj yeem muab cov ntaub ntawv qhia txog qhov pov thawj ntawm NFT.
Kev saib xyuas ruaj ntseg yog qhov tseem ceeb vim tias NFT qhov tseeb yog nyob ntawm qhov tseeb tias tus neeg tuav pov hwm txoj cai uas tsim nyog mints NFTs thiab muag lawv tsuas yog ua pov thawj tias lawv minted NFTs los ntawm thawj qhov kev saib xyuas ntawm tus tsim yuam sij. Kev saib xyuas kev nyab xeeb ntawm cov yuam sij siv los kos npe rau lawv yog qhov tseem ceeb rau cov kws ua yeeb yam los ua pov thawj tias lawv tsim cov duab kos. Hloov pauv, poob Cov Ntsiab Cai ntiag tug yuav ua rau tus kws kos duab tsis tuaj yeem lees paub qhov tsim ntawm lawv txoj haujlwm.
Nrog cov kev daws teeb meem tshiab TEE, peb yuav tsum pib pom qhov kawg ntawm NFT kev dag ntxias thiab kev dag ntxias, raws li cov kws ua yeeb yam thiab cov neeg tsim khoom tam sim no tuaj yeem ua pov thawj tias lawv tsim NFT los ntawm kev txuas NFT metadata, tus tsim cov yuam sij, thiab NFT token nws tus kheej thiab khaws cia ua ke ntawm kev hloov tsis tau. IPFS huab cia (nrog Filecoin ntawm Seal Storage Technology) lossis hauv ib lub tsev khaws khoom swiss.
Kev xa tawm TEE yog ib kauj ruam tom ntej tseem ceeb hauv kev muab txhua qhov haujlwm NFT nrog rau kev nkag mus rau qhov chaw muaj kev nyab xeeb heev uas kev ceev ntiag tug thiab kev nyab xeeb tuaj yeem siv rau hauv kev ua haujlwm cais, ua rau cov tuam txhab siv NFTs ntawm qhov ntsuas. Nws yog lub foob ntawm kev pom zoo ntawm qhov tseeb uas txhua tus tsim NFT lossis tus neeg yuav khoom yuav tsum tau hais rau.
