Ah! But I was not trying to explain how yours worked, just how adding the static server seed you described could render all those "you've changed my server seed before the roll" claims invalid.
I agree that reseting the nonce is just a choice and that it would "not" really have an influence, since in both cases it must be sequential.
That wasn't what you originally said. You said
I'm sorry I'm late to the party, but I'm just reading this now. There is one thing that Freebitco.in could do to actually get this: reset the nonce.
That's why I couldn't understand what you were getting at.
Both systems are PF, following the principle that the result can be verified. It may just be a perception bias, but I'd be more inclined to trust a static server seed that resets after getting changed, because it won't only prevent results from being skipped (both systems do that), but if there's a change on the seeds, I'd know when it happened.
I think it's just a personal preference thing. Some people prefer one system over the other. In the 4 years I've been doing this I've only had 3 people from memory requesting we change it. I would guess if we did I might get 3 people over the next 4 years asking us to change it back.
