Mantra : description, installation du nœud

MANTRA agit comme une blockchain de niveau 1 avec la sécurité comme priorité, qui respecte toutes les réglementations et les exigences de conformité. Construite sur le SDK Cosmos pour les développeurs et les institutions, la chaîne MANTRA vise à surmonter tous les obstacles qui entravent la transition en douceur des actifs du monde réel (RWA) vers la blockchain. MANTRA Chain fournit une tokenisation interopérable des actifs illiquides sur le réseau IBC et offre différents modules pour la conformité, les actifs et les tokens.
