At this point, I am not capable with addressing the thing you pointed out - the way to block fake results in open network. From the very beginning, I don't want to make the system closed-network nor login required as I want people to join the calculation instantly. Technically, I think it is impossible to prevent reporting fake result as long as it is open network system - which means my design doesn't fit to seeking rigor.

If someone starts another project that handles calculations in better way, I would like to learn from it.

I hope this comment answers to your question.

I will continue my project to seek meaningful purpose in some extent.
