One key consideration: On the blockchain, off-chain web APIs have to be different. Because of the consensus mechanisms that are at the essence of Web 3.0, you can’t just insert external data without the network agreeing to it. That’s where oracles like API3 and Chainlink come in. But unlike traditional oracles, API3 bridges the gap in the simplest possible way by setting aside the one-size-fits-all solution used by third-party oracles and empowering API providers to offer their off-chain web APIs directly to the decentralized applications. These bridging solutions promise to open Web 3.0 to a new generation of blockchain applications.
