One advantage of focusing on puzzle transactions is that finding (and taking) those funds presents no moral dilemma. It's meant to be a reward.
please clarify - how is finding/taking funds (essentially stealing) found to have no moral dilemma? and why would stealing be a reward?
or am I misunderstanding and there is no stealing being done and these are just free funds floating out there?
Why is solving cryptographic problems as a miner not stealing, while it is stealing as a key cracker exactly? Because you say so?
