The (‘Oracle’) problem is that there are no currently successful decentralized designs. The oracle problem states that "as soon as you make a smart contract rely on a single central oracle, you have totally sacrificed any decentralization benefits." (See here).It is an issue of centralization, as oracles are generally a single source of truth. An Oracle is, simply put, a “smart contract” that is able to interact with the outside world, in the world of Ethereum that is known as off-chain. I put smart contracts in quotations because some people argue that Oracles aren't exactly a real smart contract.
