Mantra: description, Node installation

MANTRA acts as a tier 1 blockchain with security as a priority, which complies with all regulations and compliance requirements. Built on top of the Cosmos SDK for developers and institutions, MANTRA Chain aims to address all the obstacles that hinder the smooth transition of real world assets (RWAs) to blockchain. MANTRA Chain provides interoperable tokenization of illiquid assets over the IBC network and offers different modules for compliance, assets and tokens.
