Randomness

The contract uses a series of random numbers to draw the raffle winners. As there is no secure random number generator on Arbitrum, those numbers will be provided to the contract in a transaction after the bidding window closes. Hashes of 10 future Ethereum mainnet blocks will be used as a source of randomness, with each of them drawing 8 raffle winners, thus 80 in total. To prevent miners tampering with the blocks in order to set the contest to their advantage, we’ll salt the hashes using a secret number S. This means that for the random numbers we’ll use the hashes of block hashes and the number S:

random_number_1 = keccak256(block_hash_1, S)

random_number_2 = keccak256(block_hash_2, S)

For transparency reasons, we commit to use a secret value S which hash equals to: keccak256(S) = 28902c742fcf74d7f6edce7c692e2be7e8c4befb8ec14a86e0422b24f714b01c

The secret value S that we used was: 0x64323832333433643661653738623538303461623966386366356436343434343637343237653564363365353334386430376264373338343561313837623131.

The following Ethereum mainnet blocks were used as a source of randomness:

15138000 15138001 15138002 15138003 15138004 15138005 15138006 15138007 15138008 15138009
