We're releasing an update soon and will be requiring users to change their Seed pair at some point today or tomorrow. When you place a roll it will simply allow you to set new provably fair seeds. Sorry for any inconvenience this may cause, it will just take a few seconds and you can get back to playing immediately. We'll be doing this once every 3 months.
We will be down for 20-30 minutes while we apply this update.
Why are you forcing a changing of the user seeds?
We took additional steps to harden PD security which are of course null without a seed rotation. We aren't setting new seeds for players, they have to do that themselves. We do this twice a year typically, will provide better notice in the future.
This is the major flaw of nonce systems which makes it NOT provably fair. In my opinion, this is magnitudes worse than non-nonce systems where users are 'vulnerable' if they do not change their client seed every round, because at least in that situation, users are still in control, whereas this situation they are not.
By not allowing users to bet nonce 'X' and beyond by something out of their control (unannounced or unexpected prevention of continued betting on current seed), users have no way of knowing that the site did not purposely prevent them from doing so, especially if they have a recognizable strategy.
A solution to this may be to enforce a hard schedule where it is quite visible and known well ahead of time, restricting continuation of betting on current seeds ONLY at these times with announcements leading up to this time. Else, you could possibly have admins be able to announce sudden 'upgrades' or 'maintenance' periods that restrict betting and completely break provably fair.
By all means, I trust Primedice and don't think that any of this is intentional, but I think you guys (@Stunna and @Edward) need to be the leading examples, especially since Edward has been so forward about 'fake provably fair' sites.
