Ojo. Installation af noden

Ojo er et sikkerhedsfokuseret decentraliseret oracle-netværk, der er designet til at understøtte Cosmos-økosystemet. Ojo indsamler prisdata fra en række forskellige kilder, både på og uden for kæden, og bruger avancerede sikkerhedsmekanismer til at sikre integriteten af de leverede data.
