For DAPP Developers

Good to know: This section is intended for developers who are building applications that consume the randomness.
If you are looking on the documentation to contribute to Nois then check For Nois Developers​
From a DAPP developer's perspective, getting randomness is as simple as 2 handlers in the contract. The first handler is GetNextRandomness(id) and the second handler is receive(randomness,id) id: This is an internal identifier within the dapp to know what the randomness is going to be used for. Imagine you have multiple players, and each one of them is rolling the dice. when player Bob rolls the dice, your DAPP chooses an id of type string to **** reference the randomness that will hold the randomness of the dice roll of Bob. In another use case you can have on the same contract rounds of lottery A and rounds of lottery B. You can set one id per lottery so that the contract knows what randomness matches what game.
You can choose whichever string you like for the id.
The id is not about routing the randomness back to your contract. The routing callback will simply go to the contract that called the nois-proxy.
randomness: This is the raw randomness hexadecimal data. Example: ba17f71e631b9c3f6ad32ab44f6031ef885f2c3021c58edaa853b539f0225ea3
