# Proof of work - does the equipment matter?

It technically doesn’t matter whether I am using a super computer or a laptop to do the proof of work, it’s simply that with a super computer I can go through the attempts much faster, which means I have a higher chance of solving the problem before anyone else and therefore claiming the reward, right?

• Isn't that the only thing that does matter? – David Schwartz Jun 15 '14 at 9:31
• How can it be that you have to generate a hash below a certain number if there are letters in the hash, and not just numbers? – user18220 Jun 21 '14 at 15:23
• You're confusing values of numbers with representations of numbers. You can represent numbers with letters if you want, the letter "A" can stand for the number ten (as can "10", "ten", "xxxxxxxxxx", "one more than nine" and a dozen other things). It's still a number. It can still be compared. We mean a hash with a lower value, regardless of how you choose to represent the number (as digits in base ten, in hexadecimal, or in scratches on a wooden board, it doesn't matter). – David Schwartz Jun 22 '14 at 5:12
