Mantra: beskrivelse, installation af knudepunkt

19.08.2024, 17:04
Indhold:

MANTRA fungerer som en tier 1-blockchain med sikkerhed som prioritet, der overholder alle regler og krav til overholdelse. MANTRA Chain er bygget oven på Cosmos SDK til udviklere og institutioner og har til formål at tackle alle de forhindringer, der hindrer en smidig overgang fra real world assets (RWA'er) til blockchain. MANTRA Chain giver interoperabel tokenisering af illikvide aktiver over IBC-netværket og tilbyder forskellige moduler til compliance, aktiver og tokens.
