Browser-solidity has some magic which resolves github-based imports automatically, however when you do this on your local machine this won't work. You can save the oraclizeAPI.sol file in your local machine and then just replace the import statement with import "oraclizeAPI.sol"; . Oraclize answers this question by implementing concept called, Authenticity Proof - The solution developed by Oraclize is instead to demonstrate that the data fetched from the original data-source is genuine and untampered. This is accomplished by accompanying the returned data together with a document called authenticity proof. I am trying to deploy a smart contract to a private Blockchain which uses oraclizeAPI.sol library code. Basically the smart contract is a small implementation of oraclize.

Here you'll find various examples that use Provable to feed smart-contracts with data from a variety of external sources. Smart contracts can interact with data living in the blockchain but it is impossible to get informations from the web. Using Oraclize, we’ll see how your smart contracts can get data from outside the blockchain and execute any API call. Some use cases can be: It’s hard to generate completely random data on the blockchain can […] Hi, Thomas from Oraclize here.
