I know, that using block hash or timestamp is not secure for gambling applications, and I know that I can use Oraclize to get a real random number. But is it possible to ask for an array of distinct numbers?
Also, even I am getting a number from Oraclize, the miners can throw the block away in the same way, until they are satisfied with the random isn't it true? So what sense of using Oraclize then? many thanks
