Advanced Questions ****************** -How do you get a random number in a contract? (Implement a self-returning gambling contract.) -============================================================================================= - -Getting randomness right is often the crucial part in a crypto project and -most failures result from bad random number generators. - -If you do not want it to be safe, you build something similar to the `coin flipper <https://github.com/fivedogit/solidity-baby-steps/blob/master/contracts/35_coin_flipper.sol>`_ -but otherwise, rather use a contract that supplies randomness, like the `RANDAO <https://github.com/randao/randao>`_. - Get return value from non-constant function from another contract ================================================================= |
