Well, you might have noticed that the number of trials is growing in an exponential way! This means that for an output of x characters you will have to make x16trials! For an output of 40 characters you will need to make 1461501637330902918203684832716283019655932542976 trials!! This number is so enormous no modern computer can make this numbsurfshark der of trials even if it works constantly till the collapse of the solar system.html) As mentioned, the miners are looking for the correct nonce that would solve the puzzle.The only rule that you have observed is that no matter how many characters you put in the machine, the produced output always has the same length.avg vpn offers
