Sigh, not really. There's ocean but that's it. Everyone else uses some sort of forward hash rate system.
Score was the old braiins system and I felt that was most fair. Ocean has developed real-time hashrate so I think theyre the purest play around aside from solo mining.
But ocean remains to be seen if they're going to do all the good things they say they will do, or if they're just lapping at being a true pleb pool.
