Celo, initialement lanc\u00e9e en tant que blockchain de couche 1 en 2020, a r\u00e9ussi sa transition vers un protocole Ethereum de couche 2 (L2) en utilisant les rollups optimistes. Cette migration vise \u00e0 am\u00e9liorer l\u2019\u00e9volutivit\u00e9 et la s\u00e9curit\u00e9 en ancrant les transactions de Celo sur l\u2019infrastructure robuste d\u2019Ethereum.<\/p>\n\n\n\n
Architecture bas\u00e9e sur Optimism<\/strong><\/p>\n\n\n\n Le nouveau syst\u00e8me utilise l\u2019OP Stack, un cadre open-source d\u00e9velopp\u00e9 par Optimism, pour mettre en \u0153uvre les rollups optimistes. Cette technologie regroupe plusieurs transactions hors cha\u00eene, r\u00e9duisant ainsi la congestion et les frais. Les rollups optimistes consid\u00e8rent par d\u00e9faut que les transactions sont valides et recourent aux preuves de fraude en cas de contestation.<\/p>\n\n\n\n Am\u00e9liorations et int\u00e9gration avec l\u2019\u00e9cosyst\u00e8me<\/strong><\/p>\n\n\n\n Avec cette mise \u00e0 niveau, Celo propose des blocs d\u2019une seconde, des co\u00fbts de transaction inf\u00e9rieurs au centime et prend en charge les stablecoins comme l\u2019USDT et l\u2019USDC pour les frais de gaz. La transition pr\u00e9serve \u00e9galement l\u2019historique de la cha\u00eene Celo sur pr\u00e8s de cinq ans et a \u00e9t\u00e9 r\u00e9alis\u00e9e de mani\u00e8re sans confiance. Ce changement devrait accro\u00eetre la liquidit\u00e9 et am\u00e9liorer la compatibilit\u00e9 avec les applications et protocoles natifs d\u2019Ethereum.<\/p>\n\n\n\n Celo, initialement lanc\u00e9e en tant que blockchain de couche 1 en 2020, a r\u00e9ussi sa transition vers un protocole Ethereum……<\/p>\n","protected":false},"author":33,"featured_media":168,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[1],"tags":[284,283,288,287,286,285,20,100],"class_list":["post-186","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-nouvelles","tag-celo","tag-ethereum-layer-2","tag-evolutivite","tag-migration-blockchain","tag-op-stack","tag-rollups-optimistes","tag-securite","tag-stablecoins"],"jetpack_featured_media_url":"https:\/\/365crypto.org\/fr\/wp-content\/uploads\/sites\/11\/2025\/03\/ec54e40e-5432-4c34-9b30-945320eafc75.webp","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/365crypto.org\/fr\/wp-json\/wp\/v2\/posts\/186","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/365crypto.org\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/365crypto.org\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/365crypto.org\/fr\/wp-json\/wp\/v2\/users\/33"}],"replies":[{"embeddable":true,"href":"https:\/\/365crypto.org\/fr\/wp-json\/wp\/v2\/comments?post=186"}],"version-history":[{"count":1,"href":"https:\/\/365crypto.org\/fr\/wp-json\/wp\/v2\/posts\/186\/revisions"}],"predecessor-version":[{"id":187,"href":"https:\/\/365crypto.org\/fr\/wp-json\/wp\/v2\/posts\/186\/revisions\/187"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/365crypto.org\/fr\/wp-json\/wp\/v2\/media\/168"}],"wp:attachment":[{"href":"https:\/\/365crypto.org\/fr\/wp-json\/wp\/v2\/media?parent=186"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/365crypto.org\/fr\/wp-json\/wp\/v2\/categories?post=186"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/365crypto.org\/fr\/wp-json\/wp\/v2\/tags?post=186"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
