En fin de compte, c\u2019est aujourd\u2019hui 3 d\u00e9cembre qu\u2019elle se produira. Il s\u2019agit d\u2019un hard fork qui a pour <strong>objectif d\u2019acc\u00e9l\u00e9rer le d\u00e9bit des transactions<\/strong> et de <strong>rendre Ethereum plus flexible<\/strong>.<\/p>\n<blockquote class=\"twitter-tweet\" data-width=\"550\" data-dnt=\"true\">\n<p lang=\"en\" dir=\"ltr\">The Fusaka upgrade is almost here.<\/p>\n<p>PeerDAS (EIP-7594) is one of the key features helping Ethereum securely scale. <\/p>\n<p>It unlocks up to 8x data throughput.

En effet, des blockchains comme <strong>Optimism<\/strong>, <strong>Arbitrum<\/strong>, <strong>Base<\/strong> ou <strong>zkSync<\/strong> peuvent saturer le r\u00e9seau en p\u00e9riode de forte activit\u00e9.

Jusqu\u2019\u00e0 pr\u00e9sent, lorsqu\u2019une blockchain L2 transmet ses donn\u00e9es \u00e0 la L1 Ethereum, elle le fait <strong>gr\u00e2ce \u00e0 des blobs<\/strong>. Il s\u2019agit de blocs de donn\u00e9es \u00e9ph\u00e9m\u00e8res. Le probl\u00e8me est que les n\u0153uds d\u2019Ethereum \u00e9taient tenus d\u2019<strong>archiver les donn\u00e9es afin de garantir leur immutabilit\u00e9<\/strong>.<\/p>\n<p>Avec Fusaka, cette pratique gourmande en ressources est remplac\u00e9e par une distribution des blobs sur l\u2019ensemble du r\u00e9seau. Les blobs de donn\u00e9es de transaction L2 sont fragment\u00e9s de sorte qu\u2019<strong>une portion \u00e9quivalente \u00e0 50 % permette de reconstruire l\u2019ensemble<\/strong>.<\/p>\n<p>La fragmentation des blobs se fait de sorte \u00e0 ce que chaque n\u0153ud conserve <strong>un huiti\u00e8me des donn\u00e9es<\/strong>. Autrement dit, d\u2019un point de vue th\u00e9orique, ceci permet d\u2019assurer le traitement de 8 fois plus de donn\u00e9es provenant des blockchains L2. Autrement dit, <strong>une multiplication x8 de la vitesse de traitement des L2<\/strong>.<\/p>\n<h2><span id=\"une_gestion_plus_intentionnelle_des_blobs_l2_dethereum\">Une gestion plus intentionnelle des blobs L2 d\u2019Ethereum<\/span><\/h2>\n<p>Notons que cette instrumentalisation des blobs n\u2019est rendue possible que gr\u00e2ce \u00e0 la gestion ind\u00e9pendante des blobs par les clients Ethereum.

Afin d\u2019\u00e9viter que le co\u00fbt des blobs L2 grimpe pendant les p\u00e9riodes de congestion, la <strong>proposition EIP-7918<\/strong> pr\u00e9voit une <strong>sorte de cagnotte syst\u00e9matique<\/strong>.<\/p>\n<p>Lorsque les frais sont faibles, une partie des co\u00fbts est conserv\u00e9e dans une r\u00e9serve. Cette r\u00e9serve est ensuite utilis\u00e9e pour couvrir les frais des blobs lors des congestions afin d\u2019\u00e9viter une hausse des prix. Ceci a pour effet de r\u00e9duire les co\u00fbts pour les L2, mais surtout de <strong>rendre ces co\u00fbts stables et beaucoup plus pr\u00e9visibles<\/strong>.<\/p>\n<h2><span id=\"une_augmentation_de_la_limite_de_gas_dethereum\">Une augmentation de la limite de gas d\u2019Ethereum<\/span><\/h2>\n<p>La proposition EIP-7935 introduit l\u2019<a href=\"https:\/\/x.com\/VitalikButerin\/status\/1993676389812232490\" target=\"_blank\" rel=\"noopener noreferrer\">\u00e9l\u00e9vation de la limite de gas de 36 millions \u00e0 60 millions<\/a>. Pour comprendre son importance, rappelons que le gas est une mesure du pouvoir de calcul requis pour une transaction. Autrement dit, <strong>plus les transactions sont complexes et plus leur co\u00fbt est \u00e9lev\u00e9<\/strong>.<\/p>\n<p>De fait, les contrats intelligents et les transactions peuvent avoir des frais de gas tr\u00e8s vari\u00e9s. Avec la <strong>proposition <\/strong><strong>EIP-7935<\/strong>, Ethereum peut ex\u00e9cuter des contrats intelligents hautement complexes sans encombrement. Les limites de gas devraient cesser d\u2019\u00eatre un obstacle \u00e0 l\u2019innovation en mati\u00e8re de <strong>contrats intelligents<\/strong> et de <strong>protocoles programmables on-chain<\/strong>.<\/p>\n<p>Cette proposition est toutefois encadr\u00e9e par d\u2019autres propositions qui emp\u00eachent un ballonnement incontr\u00f4lable de la taille des blocs. Ainsi, de <strong>nouvelles limites sup\u00e9rieures de gas<\/strong> pour les transactions et des <strong>limites de taille de bloc<\/strong> sont pr\u00e9vues.<\/p>\n<p>Concr\u00e8tement, ceci signifie que tout type d\u2019application DeFi peut tourner sur Ethereum sans contrainte. Par exemple, les contrats intelligents de memecoins comme <a href=\"https:\/\/icobench.com\/fr\/visit\/maxidoge\" target=\"_blank\" rel=\"noopener nofollow\">Maxi Doge<\/a> peuvent \u00eatre ex\u00e9cut\u00e9s sur la L1 d\u2019Ethereum et <strong>op\u00e9rer sans ralentissement<\/strong> m\u00eame lorsque le memecoin deviendra populaire. <strong>Achetez vos jetons Maxi Doge<\/strong> maintenant et <strong>investissez sur un memecoin Ethereum prometteur<\/strong>.<\/p>\n<div style=\"background: #00DBC1;margin: auto;width: 50%;text-align: center;padding: 8px;border-radius: 5px;background-image: linear-gradient(107deg,#00DBC1,#00E676);color: white;padding-left: 1em;padding-right: 1em;font-size: 16px\"><a style=\"text-decoration: none;color: white\" href=\"https:\/\/icobench.com\/fr\/visit\/maxidoge\" target=\"_blank\" rel=\"noopener nofollow\">Acheter Maxi Doge<\/a><\/div>\n<p style=\"text-align: center\"><em>Les crypto-actifs repr\u00e9sentent un investissement risqu\u00e9.<\/em><\/p>\n<h2><span id=\"amelioration_de_lethereum_virtual_machine_evm\">Am\u00e9lioration de l\u2019Ethereum Virtual Machine (EVM)<\/span><\/h2>\n<p><strong>EVM (Ethereum Virtual Machine)<\/strong> est un des outils les plus importants de l\u2019\u00e9cosyst\u00e8me Ethereum.
