This is due to how Ethereum works: Block Height Endpoint curl 'https: These systems are called authenticity proofswhich enable auditability of the oracle's service record in delivering untampered data. Oraclize is the leading oracle service for smart contracts and blockchain applications, serving thousands of requests every day on platforms like EthereumRootstockR3 CordaHyperledger Fabric and EOS. The gas price can also affect how quickly a transaction takes place depending on what other transactions are available with a more profitable gas price for miners.
