Fr\u00e5n starten har NFT alltid varit polariserande.<\/p>\n\n\n\n
NFT skapas genom en process som kallas gruvdrift, som kr\u00e4ver betydande m\u00e4ngder energi. En studie fann att processen att bryta en enda Bitcoin anv\u00e4nder mer energi \u00e4n den \u00e5rliga f\u00f6rbrukningen i 159 l\u00e4nder. S\u00e5 n\u00e4r dessa dyra blockkedjebaserade JPEG-filer hittade sin v\u00e4g in i det vanliga utrymmet i b\u00f6rjan av f\u00f6rra \u00e5ret v\u00e4ckte det m\u00e5nga spekulationer om vad de betydde f\u00f6r framtiden f\u00f6r digital konst.<\/p>\n\n\n\n
NFT skapades som ett s\u00e4tt att representera digital brist, men vissa aktivister \u00e4r oroade \u00f6ver deras milj\u00f6p\u00e5verkan.<\/p>\n\n\n\n
S\u00e5 det v\u00e4cker fr\u00e5gan om icke-fungibla tokens relativa energif\u00f6rbrukning: Bitcoin (BTC) och andra kryptovalutor har l\u00e4nge varit k\u00e4nda f\u00f6r att kr\u00e4va enorma m\u00e4ngder energi, varav mycket kommer fr\u00e5n billiga fossila br\u00e4nslen. Kan NFTs, som ocks\u00e5 \u00e4r baserade p\u00e5 blockchain-teknik, vara mer h\u00e5llbara?<\/p>\n\n\n\n
Svaret \u00e4r faktiskt komplicerat. \u00c4ven om det \u00e4r m\u00f6jligt att skapa NFT:er som anv\u00e4nder mindre energi - eller till och med ingen energi alls - kr\u00e4ver de allra flesta av dem fortfarande en hel del str\u00f6m. Och n\u00e4r efterfr\u00e5gan p\u00e5 NFTs v\u00e4xer,<\/p>\n\n\n\n
Oberoende forskare, Kyle McDonald inspirerades av en online bitcoin utmaning<\/a> f\u00f6r att skapa en instrumentpanel f\u00f6r att best\u00e4mma procentandelen av Ethereum-transaktioner som kan h\u00e4nf\u00f6ras till NFT. han delad<\/a> en annan instrumentpanel i slutet av 2021, som best\u00e4mmer utsl\u00e4ppen fr\u00e5n hela Ethereum-n\u00e4tverket.<\/p>\n\n\n\n Mcdonalds arbete \u00e4r informerat om behovet av att ha h\u00e5rda, aktuella data till hands innan beslut fattas.<\/p>\n\n\n\n "Om du vill vara en effektiv klimataktivist \u00e4r det viktigt att ha siffror som \u00e4r s\u00e5 uppdaterade som m\u00f6jligt", sa han. "Det \u00e4r mycket l\u00e4ttare f\u00f6r mig att presentera ett fall f\u00f6r varf\u00f6r vi beh\u00f6ver \u00e4ndra n\u00e5got om jag kan s\u00e4ga," H\u00e4r \u00e4r data. H\u00e4r \u00e4r vad det betyder.'\u201d<\/p>\n\n\n\n Blockkedjor \u00e4r gigantiska offentliga listor \u00f6ver transaktioner; varje ny transaktion som l\u00e4ggs till i listan verifieras av ett n\u00e4tverk av datorer som k\u00f6r speciell programvara. Ethereum-n\u00e4tverket, som k\u00f6rs p\u00e5 kryptovalutan med samma namn, \u00e4r den st\u00f6rsta och mest popul\u00e4ra blockkedjan f\u00f6r NFT. Det \u00e4r ocks\u00e5 en av de mest energikr\u00e4vande.<\/p>\n\n\n\n I september 2020 uppskattade ett unders\u00f6kningsf\u00f6retag vid namn Digiconomist att varje Ethereum-transaktion anv\u00e4nde lika mycket el som ett amerikanskt hem anv\u00e4nder p\u00e5 tv\u00e5 dagar.<\/p>\n\n\n\n Dessa olika processer f\u00f6r bekr\u00e4ftelse \u00e4r k\u00e4nda som "konsensusmekanismer" - hur detta n\u00e4tverk av datorer n\u00e5r en \u00f6verenskommelse om vilka transaktioner som \u00e4r legitima eller falska.<\/p>\n\n\n\n Den \u00e4ldsta konsensusmekanismen i kryptosf\u00e4ren \u00e4r k\u00e4nd som "proof-of-work". Det anv\u00e4ndes f\u00f6rst i den ursprungliga kryptovalutan, bitcoin, och inneb\u00e4r att datorer \u00e4gnar sig \u00e5t att l\u00f6sa komplexa matematiska problem.<\/p>\n\n\n\n Datorn som f\u00f6rst l\u00f6ser problemet bel\u00f6nas med nya bitcoins \u2013 s\u00e5v\u00e4l som transaktionsavgifterna som ing\u00e5r i datablocket som de behandlade. Kappl\u00f6pet om att bli f\u00f6rst kr\u00e4ver ocks\u00e5 mycket energi. Bitcoin, Ethereum, Dogecoin, Monero och Zcash fungerar alla p\u00e5 detta s\u00e4tt.<\/p>\n\n\n\n F\u00f6r att ber\u00e4kna ett direkt samband mellan NFT och CO2-utsl\u00e4pp, skulle man beh\u00f6va ber\u00e4kna om myntande NFT har \u00f6kat energibehovet f\u00f6r det \u00f6vergripande Ethereum-n\u00e4tverket. Efterfr\u00e5gan p\u00e5 minting NFTs har h\u00f6jt priset p\u00e5 Ethereum-gaspriserna \u00e4r f\u00f6r n\u00e4rvarande p\u00e5 den h\u00f6gsta n\u00e5gonsin. Det genomsnittliga gaspriset f\u00f6r en Ethereum-transaktion \u00e4r nu \u00f6ver $23. Detta beror p\u00e5 m\u00e4ngden ber\u00e4kningskraft som kr\u00e4vs f\u00f6r att skapa NFT, vilket t\u00e4pper till Ethereum-n\u00e4tverket.<\/p>\n\n\n\n N\u00e4r efterfr\u00e5gan p\u00e5 NFT \u00f6kar, \u00f6kar ocks\u00e5 priset p\u00e5 Ethereum och utsl\u00e4ppen i samband med det<\/p>","protected":false},"excerpt":{"rendered":" From inception, NFTs have always been polarizing.
