Les grandes institutions m\u00e8nent des \u00e9valuations internes, tandis que les banques de taille plus modeste en sont encore aux premi\u00e8res \u00e9tapes de la planification.<\/p>\r\n<p>L\u2019HKMA a adopt\u00e9 une approche structurelle en introduisant un kit d\u2019outils PQC avec l\u2019Universit\u00e9 des sciences et technologies de Hong Kong, des ateliers obligatoires et un cadre align\u00e9 sur les normes post-quantiques du NIST. Elle fixera des attentes minimales pour les conseils d\u2019administration et la direction g\u00e9n\u00e9rale concernant la strat\u00e9gie et la gouvernance PQC.<\/p>\r\n<p>Ce score r\u00e9v\u00e8le non seulement un manque de pr\u00e9paration, mais souligne aussi la capacit\u00e9 du r\u00e9gulateur \u00e0 mesurer, publier et imposer une responsabilit\u00e9 aux acteurs du march\u00e9.<\/p>\r\n<p>L\u2019HKMA vise une pr\u00e9paration compl\u00e8te du secteur d\u2019ici 2030, s\u2019alignant sur des normes internationales telles que le m\u00e9mo NSM-10 de la Maison Blanche, qui cible une PQC approuv\u00e9e par le NIST d\u2019ici 2035, rendant l\u2019objectif de Hong Kong particuli\u00e8rement ambitieux.<\/p>\r\n<h2><span id=\"bip-360_et_bip-361_le_fosse_de_gouvernance_face_a_la_menace_quantique\">BIP-360 et BIP-361 : le foss\u00e9 de gouvernance face \u00e0 la menace quantique<\/span><\/h2>\r\n<p>Les propositions <strong>BIP-360<\/strong> et <strong>BIP-361<\/strong> sont des jalons importants pour Bitcoin.

Cette mesure pourrait rendre environ 1,7 million de BTC, principalement li\u00e9s \u00e0 <strong>Satoshi Nakamoto<\/strong>, inaccessibles si une date limite de migration stricte \u00e9tait impos\u00e9e.<\/p>\r\n<p>Les deux propositions manquent d\u2019un m\u00e9canisme de mise en \u0153uvre contraignant.
