A smart contract is an automatically executed program located on the blockchain that can determine the validity of off-chain data based on pre-established conditions and trigger on-chain transactions when these conditions are met. Oracles serve as a data input mechanism that uploads  off-chain data to the blockchain, making it a part of on-chain data."}]}],"pr":"4f1dc63ba0e44a208941fd7249d9aae7d5b8ecaa7ad2c97964527615c6129df5"}
