Jusqu\u2019ici, de nombreuses plateformes publiques s\u2019appuyaient sur des technologies \u00e9trang\u00e8res. <strong>Cette d\u00e9pendance repr\u00e9sentait un risque<\/strong>, notamment en mati\u00e8re de cybers\u00e9curit\u00e9.<\/p>\n<p>D\u00e9sormais, le pays dispose d\u2019une infrastructure nationale capable de traiter, prot\u00e9ger et certifier les donn\u00e9es publiques. Ce mouvement s\u2019inscrit dans une vision plus large : <strong>faire du Vietnam un leader r\u00e9gional de la transformation num\u00e9rique<\/strong>.<\/p>\n<p>Ce projet blockchain cr\u00e9e aussi des opportunit\u00e9s pour les startups locales. Elles pourront d\u00e9velopper des outils compatibles avec NDAChain : plateformes d\u2019identit\u00e9, registres de donn\u00e9es, tra\u00e7abilit\u00e9 alimentaire ou m\u00e9dicale.

Sans accompagnement, l\u2019outil risque de rester sous-exploit\u00e9.<\/p>\n<p>Le deuxi\u00e8me d\u00e9fi est technique. La maintenance des n\u0153uds et la s\u00e9curit\u00e9 du code exigent une rigueur constante. Un bug ou une faille pourrait entacher la confiance du public. Le pays mise sur la collaboration public-priv\u00e9 pour garantir une surveillance continue du r\u00e9seau.<\/p>\n<p>Enfin, l\u2019adoption d\u00e9pendra aussi de la <strong>capacit\u00e9 du syst\u00e8me \u00e0 s\u2019int\u00e9grer aux outils existants<\/strong>.
