BKC Oracle is an important tool for developing smart contracts or dApps. The data oracle functions as a medium to bring data from off-chain to the blockchain via smart contracts. Data Oracle can process data from off-chain, for example, Weather, sporting results, temperature, and high-risk data (such as stock or asset prices, election results, or even blockchains).
