There’s a need for real-world data to be connected to blockchain networks in order to ease production of smart contract principles and their enforceability. Data inherent platforms, which are blockchains, draw data from themselves. Despite being heavily based on data, it is impossible for them to get off-chain data (external data from the blockchain) hence a consequential need for blockchain network oracles.

Band Protocol connects blockchains, so that dApps pull external data from trusted data suppliers and internal data from other blockchains. Some data extracted by blockchain oracles comprise fiat to exchange data, BTC hash speed, weather updates, and ETH gas prices.
