🎰 Randomness is tricky on a public deterministic blockchain. The block hash is an easy to use, but
|
||
very weak form of randomness. This challenge will give you an example of a contract using the block
|
||
hash to create random numbers. This randomness is exploitable. Other, stronger forms of randomness
|
||
include commit/reveal schemes, oracles, or VRF from Chainlink.

||

|

<p className="text-lg mt-2">
|
||
🧤 Every time a player rolls the dice, they are required to send .002 Eth. 40 percent of this value
|
||
is added to the current prize amount while the other 60 percent stays in the contract to fund future
|
||
prizes. Once a prize is won, the new prize amount is set to 10% of the total balance of the DiceGame
|
||
contract.
|
||
</p>
|
||
<p className="text-lg mt-2">
|
||
🧨 Your job is to attack the Dice Game contract! You will create a new contract that will predict
|
||
the randomness ahead of time and only roll the dice when you′re guaranteed to be a winner!
