Answer: Witnet is a decentralized oracle protocol that allows smart contracts to interact with real-world data. It ensures strong crypto-economic guarantees that allow for trustless and secure data exchange. This allows for a wide range of applications, such as providing access to real-time data feeds, off-chain calculations, and more. With the integration of Witnet with Klaytn and Cypress mainnet, users can now utilize this protocol in their smart contracts. This opens up a range of possibilities and use cases that can be implemented using the Witnet protocol.
