i planned to make a pool with limited registration and monitor it so that users will mine fairly(no botnets, no constant hopping in when hashrate is low). i have to create a valid TOS for this. do you think it worths a try?
i didn't dig into other reward systems currently used, but since they are all based on PPS, so i can't really play this casino without being afraid of going low, is that correct? so i thought maybe i'll set up a proportional pool and keep an eye on it while i can so that it will be fair for both miners and myself.
look into pplns - has pretty much the same risk to operator as proportional and is a fair payout system, I prefer DGM but the maths confuses miners sometimes.
My opinion is proportional is not worth the try, before moving away from prop my team (and quite a few other pools) tried to work out how to make proportional "fair", doing some research you will find the same,slush implemented a system that is better than prop, but still hoppable.
good luck with it
oh and prepare to be on call 24/7/365 and deal with all sorts of issues - real or imagined,
running a pool is not "set and forget" if you want to do it properly
