Make sure your contract has sufficient LINK, and * @dev call requestRandomness(keyHash, fee, seed), where seed is the input you * @dev want to generate randomness from. * * @dev Once the VRFCoordinator has received and validated the oracle's response * @dev to your request, it will call your contract's fulfillRandomness method. * * @dev The randomness argument to fulfillRandomness is the actual random value * @dev generated from your seed. * * @dev The requestId argument is generated from the keyHash and the seed by * @dev makeRequestId(keyHash, seed). If your contract could have concurrent * @dev requests open, you can use the requestId to track which seed is * @dev associated with which randomness. See VRFRequestIDBase.sol for more * @dev details. (See "SECURITY CONSIDERATIONS" for principles to keep in mind, * @dev if your contract could have multiple requests in flight simultaneously.) * * @dev Colliding `requestId`s are cryptographically impossible as long as seeds * @dev differ. (Which is critical to making unpredictable randomness! See the * @dev next section.) * * ***************************************************************************** * @dev SECURITY CONSIDERATIONS * * @dev A method with the ability to call your fulfillRandomness method directly * @dev could spoof a VRF response with any random value, so it's critical that * @dev it cannot be directly called by anything other than this base contract * @dev (specifically, by the VRFConsumerBase.rawFulfillRandomness method). * * @dev For your users to trust that your contract's random behavior is free * @dev from malicious interference, it's best if you can write it so that all * @dev behaviors implied by a VRF response are executed *during* your * @dev fulfillRandomness method. If your contract must store the response (or * @dev anything derived from it) and use it later, you must ensure that any * @dev user-significant behavior which depends on that stored value cannot be * @dev manipulated by a subsequent VRF request. * * @dev Similarly, both miners and the VRF oracle itself have some influence * @dev over the order in which VRF responses appear on the blockchain, so if * @dev your contract could have multiple VRF requests in flight simultaneously, * @dev you must ensure that the order in which the VRF responses arrive cannot * @dev be used to manipulate your contract's user-significant behavior. * * @dev Since the ultimate input to the VRF is mixed with the block hash of the * @dev block in which the request is made, user-provided seeds have no impact * @dev on its economic security properties. They are only included for API * @dev compatability with previous versions of this contract. * * @dev Since the block hash of the block which contains the requestRandomness * @dev call is mixed into the input to the VRF *last*, a sufficiently powerful * @dev miner could, in principle, fork the blockchain to evict the block * @dev containing the request, forcing the request to be included in a * @dev different block with a different hash, and therefore a different input * @dev to the VRF. However, such an attack would incur a substantial economic * @dev cost.
