Hey! I have a great idea for you!
You could introduce a new type of blockchain security called POG or "Proof of Girth".
You could have a special device that is fastened onto the penis and measures it. Kind of a cross between an ASIC miner and a cock ring.
Anyway, the bigger your penis, the more chance you have of finding a block. (It is perfectly acceptable to make your penis "grow" by whatever means necessary.)
And the best part is that there is absolutely no way that there could ever be a 51% attack. I mean, they guy would have to have a dick the size of a skyscraper.
When I get the wallet downloaded I'll post the address that you can send my bounty to. I trust it will be a big one.
