La signature \u00e0 s\u00e9curit\u00e9 quantique est d\u00e9sormais disponible sur le r\u00e9seau principal NEAR.<\/p>\n

Cela fait de NEAR l\u2019une des premi\u00e8res blockchains en production dot\u00e9e d\u2019un syst\u00e8me de signature post-quantique approuv\u00e9 par le NIST.<\/p>\n

\u2013 Protocole NEAR (@NEARProtocol)20 juillet 2026<\/a><\/p>\n<\/blockquote>\n

Le d\u00e9ploiement permet aux d\u00e9veloppeurs et aux utilisateurs de commencer \u00e0 adopter la cryptographie post-quantique sans modifier les adresses de compte.\u00a0<\/span><\/p>\n

Au lieu de cela, les utilisateurs peuvent alterner leurs cl\u00e9s de compte via une seule transaction en cha\u00eene.<\/span><\/p>\n

Selon NEAR, le r\u00e9seau peut prendre en charge cette approche car les noms de comptes restent s\u00e9par\u00e9s des cl\u00e9s cryptographiques sous-jacentes.\u00a0<\/span><\/p>\n

Cette conception \u00e9limine le besoin d\u2019une migration compl\u00e8te des actifs pendant la transition.<\/span><\/p>\n

Le protocole indique \u00e9galement que les constructeurs peuvent d\u00e9j\u00e0 faire pivoter les cl\u00e9s de compte vers ML-DSA en utilisant la derni\u00e8re version de NEAR CLI. La documentation sur la fonctionnalit\u00e9 est devenue disponible parall\u00e8lement \u00e0 la mise \u00e0 niveau.<\/span><\/p>\n

La m\u00eame mise \u00e0 niveau du r\u00e9seau a \u00e9galement activ\u00e9 le reharding dynamique sur le NEAR<\/span>cha\u00eene de blocs<\/span><\/a>. Cette fonctionnalit\u00e9 permet au protocole d’ajuster automatiquement sa structure de partition \u00e0 mesure que la demande du r\u00e9seau \u00e9volue.<\/span><\/p>\n

Au lieu de s’appuyer sur des mises \u00e0 niveau manuelles ou des votes des validateurs, le r\u00e9seau peut d\u00e9sormais faire \u00e9voluer les ressources en fonction de l’activit\u00e9. Cela vise \u00e0 am\u00e9liorer les performances \u00e0 mesure que les applications et les volumes de transactions augmentent.<\/span><\/p>\n

BSCN a \u00e9galement signal\u00e9 la mise \u00e0 niveau, d\u00e9crivant NEAR comme l’un des premiers r\u00e9seaux blockchain \u00e0 combiner une signature quantique s\u00e9curis\u00e9e pr\u00eate pour la production avec une mise \u00e0 l’\u00e9chelle automatique sur le r\u00e9seau principal.<\/span><\/p>\n

La s\u00e9curit\u00e9 quantique attire l’attention sur la cryptographie<\/b><\/h2>\n

L\u2019\u00e9quipe NEAR a d\u00e9clar\u00e9 que l\u2019informatique quantique pr\u00e9sente un d\u00e9fi \u00e0 long terme pour la s\u00e9curit\u00e9 de la blockchain.\u00a0<\/span><\/p>\n

Dans un<\/span>sujet post\u00e9 sur X<\/span><\/a>, le protocole r\u00e9f\u00e9renc\u00e9 estime qu’environ 470 milliards de dollars de Bitcoin restent expos\u00e9s \u00e0 de futures attaques quantiques en raison des m\u00e9thodes cryptographiques actuelles.<\/span><\/p>\n

De nombreux r\u00e9seaux cryptographiques majeurs, notamment Bitcoin et Ethereum, ont discut\u00e9 de la s\u00e9curit\u00e9 post-quantique dans le cadre de leurs futurs plans de mise \u00e0 niveau.\u00a0<\/span><\/p>\n

NEAR a d\u00e9clar\u00e9 que son mod\u00e8le de compte permettait au protocole d’introduire la fonctionnalit\u00e9 plus t\u00f4t que de nombreuses autres cha\u00eenes.<\/span><\/p>\n

Le protocole a \u00e9galement confirm\u00e9 qu’il travaillait avec les d\u00e9veloppeurs de portefeuilles pour prendre en charge la nouvelle norme de signature.\u00a0<\/span><\/p>\n

Bien que la mise \u00e0 niveau soit d\u00e9sormais active sur le r\u00e9seau principal, ses performances \u00e0 long terme deviendront plus claires \u00e0 mesure que les d\u00e9veloppeurs et les utilisateurs adopteront la nouvelle norme cryptographique dans l’\u00e9cosyst\u00e8me NEAR.<\/span><\/p>\n
