Derri\u00e8re ce changement se joue bien plus qu\u2019un choix d\u2019algorithme. Alors Ethereum revoit les fondations cryptographiques de sa future architecture. Une nouvelle approche promet d\u00e9sormais de meilleures performances, une auditabilit\u00e9 renforc\u00e9e et une int\u00e9gration plus s\u00fbre. Reste \u00e0 comprendre pourquoi Poseidon a perdu la course, quels gains offre son rempla\u00e7ant et \u00e0 quel rythme cette transition pourrait atteindre le r\u00e9seau. <\/p>\n<p>L\u2019article <a rel=\"nofollow\" href=\"https:\/\/www.cointribune.com\/face-au-risque-quantique-ethereum-prepare-sa-defense-et-revoit-ses-choix-cryptographiques\/\">Face au risque quantique, Ethereum pr\u00e9pare sa d\u00e9fense et revoit ses choix cryptographiques<\/a> est apparu en premier sur <a rel=\"nofollow\" href=\"https:\/\/www.cointribune.com\/\">Cointribune<\/a>.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>La menace quantique pousse Ethereum \u00e0 revoir ses choix cryptographiques.
