I came across some posts about a certain
puzzle transaction that sent some good 32 BTC to 256 addresses.
What's the point in brute forcing all of these addresses. Aren't they empty?
Maybe you mean the 1000 Bitcoin puzzle challenge? It's no longer 32 BTC. The purpose of it existing is to have a measurement on how fast they can be solved in order to plan for a change if necessary. Change of what? well of course when you get robbed, you'd change the locks.😉
