Mantra: descrizione, installazione del nodo

19.08.2024, 17:04

MANTRA agisce come una blockchain di livello 1 con la sicurezza come priorità, che rispetta tutte le normative e i requisiti di conformità. Costruita sulla base dell'SDK Cosmos per gli sviluppatori e le istituzioni, MANTRA Chain mira ad affrontare tutti gli ostacoli che impediscono una transizione fluida degli asset del mondo reale (RWA) alla blockchain. MANTRA Chain fornisce una tokenizzazione interoperabile di asset illiquidi sulla rete IBC e offre diversi moduli per la compliance, gli asset e i token.

Installazione del nodo

Mantra

Requisiti minimi di sistema:

Tipo di nodo: Testnet
CPU: 4
RAM: 8 GB
Memoria: 150GB

Installazione tramite script automatico

wget -O mantrat https://raw.githubusercontent.com/111STAVR111/props/main/Mantra/mantrat && chmod +x mantrat && ./mantrat

Installazione manuale

Preparazione del server:

sudo apt update && sudo apt upgrade -y
