En juillet, c\u2019est au tour du code source du web de l\u2019informaticien Tim Berners-Lee d\u2019\u00eatre vendu cette fois \u00e0 5,4 millions de dollars. Ce sont les NFTs qui ont permis ces transactions particuli\u00e8res aux sommes colossales. De leur nom anglais \u00ab<em>non-fungible token\u00bb<\/em>, ces jetons virtuels non fongibles \u2013 c\u2019est-\u00e0-dire uniques \u2013 permettent la vente du titre de propri\u00e9t\u00e9 num\u00e9rique de tout objet, qu\u2019il soit physique ou digital.<\/p>\n<p>Rapidement, les NFT ont repr\u00e9sent\u00e9 une opportunit\u00e9 pour les artistes num\u00e9riques. Ils ont en effet permis d\u2019authentifier ce qui pouvait jusqu\u2019alors \u00eatre plagi\u00e9 infiniment sur internet.<\/p>\n<p>Mais attention, \u00eatre propri\u00e9taire d\u2019un NFT n\u2019en revient pas forc\u00e9ment \u00e0 poss\u00e9der le bien digital en lui-m\u00eame, pr\u00e9cise Jean-Marc Seigneur, directeur de la formation en d\u00e9veloppement d\u2019applications avec blockchain de l\u2019Universit\u00e9 de Gen\u00e8ve. Par exemple, l\u2019acqu\u00e9reur d\u2019un NFT d\u2019un tableau ne peut en contester la vente aux ench\u00e8res de l\u2019\u0153uvre. \u00abLe plus souvent, l\u2019acheteur d\u00e9tient le droit d\u2019acc\u00e9der au bien et d\u2019effectuer certaines op\u00e9rations\u00bb, pr\u00e9cise le professeur.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-12253\" src=\"https:\/\/largeur.com\/wp-content\/uploads\/2021\/10\/Large271021.jpg\" alt=\"\" width=\"468\" height=\"311\" srcset=\"https:\/\/largeur.com\/wp-content\/uploads\/2021\/10\/Large271021.jpg 468w, https:\/\/largeur.com\/wp-content\/uploads\/2021\/10\/Large271021-300x199.jpg 300w, https:\/\/largeur.com\/wp-content\/uploads\/2021\/10\/Large271021-272x182.jpg 272w\" sizes=\"auto, (max-width: 468px) 100vw, 468px\" \/><\/p>\n<p>\u00abPour les entreprises, la technologie des NFT leur permet d\u2019avoir des certificats de propri\u00e9t\u00e9 num\u00e9rique qui ne peuvent pas \u00eatre falsifi\u00e9s, explique Jean-Marc Seigneur. Avec la blockchain, tout est recopi\u00e9 dans des milliers de serveurs ind\u00e9pendants. On ne peut pas tricher et par exemple effacer ou dupliquer un titre de propri\u00e9t\u00e9.\u00bb Cette technologie de certification se r\u00e9v\u00e8le utile \u00e0 tout secteur o\u00f9 la lutte contre la contrefa\u00e7on est un enjeu cl\u00e9. Les NFTs s\u00e9duisent ainsi d\u2019autres secteurs au-del\u00e0 du monde de l\u2019art, \u00e0 l\u2019instar de l\u2019industrie du luxe. Hublot a inaugur\u00e9 la pratique en mai 2021 en vendant une de leur montre avec sa jumelle num\u00e9rique. Lorsqu\u2019un client ach\u00e8te une montre, il obtient alors \u00e9galement un NFT sur un portefeuille num\u00e9rique contenant le mod\u00e8le et le num\u00e9ro de s\u00e9rie de sa montre. Une \u0153uvre ou un produit ne risque ainsi plus d\u2019\u00eatre faux puisque de son historique est inscrit dans une blockchain, ce qui permet une tra\u00e7abilit\u00e9 r\u00e9put\u00e9e infaillible. Cette technologie pourrait donc repr\u00e9senter d\u2019int\u00e9ressantes opportunit\u00e9s d\u2019authentification des produits pour les PME, et ce dans divers secteurs.<\/p>\n<p>Le sp\u00e9cialiste en technologies digitales Yves Benna\u00efm nuance n\u00e9anmoins: \u00abLe fait d\u2019\u00eatre certifi\u00e9 par la blockchain, n\u2019est pas sans risque, explique-il. Il faut se poser la question de quelle blockchain est utilis\u00e9e, et de son \u00e9ventuelle vuln\u00e9rabilit\u00e9 \u00e0 des attaques ext\u00e9rieures ou internes.\u00bb Un avis partag\u00e9 par Jean-Marc Seigneur: \u00abIl est crucial que la blockchain qui encode les NFT soit publique et d\u00e9centralis\u00e9e. Si les NFT sont sur une blockchain peu utilis\u00e9e, la p\u00e9rennit\u00e9 des certificats num\u00e9riques n&rsquo;est pas garantie dans le temps car celle-ci pourrait disparaitre.\u00bb<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ces derniers mois, le monde de l\u2019art num\u00e9rique a vu s\u2019\u00e9changer des jetons virtuels, aussi appel\u00e9s NFTs, pour des sommes atteignant des millions.
