The most pressing question is always, how can I verify that the winner of your competitions won fair and square?
The answer is, it’s on-chain! And on top of that, the random winning number comes from a trusted, independent, third party named Chainlink!
Chainlink has a set of smart contracts they offer called Chainlink VRF.
These contracts allow us to request a number from them that is guaranteed to be random, trusted, and tamper-proof!
So how do you use Chainlink VRF?
We use Chainlink’s VRF contracts every day for our daily competitions! And we also use it for our big Lambo events!
The number that is returned from Chainlink’s smart contracts is used to determine the winning tickets for our Jackpots. You can see how the winning tickets are derived from the random number here.
For this article, we want to show you specifically how we request the random number, and how the random number is returned to us on-chain for everyone to see!
How do you request the random number?
To request the random number, we go to our random number generator, and we call the getRandomNumber function from our deployer. Only our deployer is able to call that function. Nobody else. And you can verify it in the code.
Here’s a sample screenshot for one of our previous dailies.
The transaction associated with this request can be seen at https://medium.com/r/?url=https%3A%2F%2Fbscscan.com%2Ftx%2F0xa400e669636203892aa48fe6b48787d664d8e9dfc12394603da2bca94655437d%23eventlog.
Scrolling down to the last log on that transaction, we can see a requestID.
This requestID can be used anytime in the future to retrieve the random number that is associated with this request!
How do you view the random number?
The request ID for the example above is BCFD18AE207E95D5A682336425D13E2179AF563B79B3F23C4DB90B913537DB33
If you take that request ID and enter it, prefixed with a 0x, in the potResultHistory field of our random number generator, you can see the random number that is associated with that request.
In this case, the random number is 32348944249030050051462067070971608188121853605915475450281631041640789425975
Here’s a screenshot demonstrating it.
There you can see all that you need to verify the random number that is returned from Chainlink, and used for our Jackpots!
That, combined with the explanation of how we use that random number to determine the winner, gives you the full picture of how our Daily and Lambo Jackpots work!
