Yes, it's proportional (for now). After we get some more hashing power I'll likely implement a PPS option as well. Stats are time-delayed to help combat pool hopping.
Additionally, I'll be adding an auto-payout threshold once I have the time to set it up.
Proportional, not score-based? Sigh, guess I'm stuck on Slush where people can't steal from me.
I should write a pool hopper and join the ranks of the thieves.
Yes, proportional. You solve x of y shares of solved block. You recieve x/y shares of the bonus 50coin.
