Isn't there a way to set up a server that generates the server seeds and sends them to just-dice, but that doesn't allow those seeds to be read out ahead of time, i.e. before they are sent?
You'll always have an entity that is able to determine the server seed.Can you explain why that is the case? Isn't there a way to set up as a system that, once it is running, doesn't allow changes to it anymore, i.e. it does what it needs to do (sending server seeds, reveal one if asked by player), but doesn't allow additional changes or attempts to read out data?
If that is a problem that is provably impossible to solve (say, a know problem in CS), then I'm not going to continue arguing of course
If you pull the seed from another server for each roll, it still needs to be saved somewhere. If we assume doog is evil, he would not be able to determine how long the seed is valid, but at least he got it. But that would only shift the responsibility to another entity. Also you can't prohibit reading the seed, since the server needs it the rolls and if the server gets it, ultimately doog gets it.
