no, an oracle is another smart contract that is called by the main contract, the oracle smart contract logs an event, this event triggers sources of truth (servers), each source of truth provides information for the oracle contract by modifying its state, the oracle contract decides if the data is reliable and calls the main contract if so
But there must always be a point where the oracle interacts with the real world, right? Which immediately becomes a point of centralization, which -seems to me- kinda defeats the purpose of having a decentralized system
