So we've been plagued with poolhoppers, that abuse our pool. The only correct action we can take to these abusers, is to change our payment system, in such a way that it becomes less interesting for poolhoppers (and therefore more interesting for fair miners). We are going to change our pool to a PPLNS pool.
What does this mean:
We will payout for all last N shares submitted, where N is defined as the current difficulty divided by 2.
In other words, when a block is found, we will look at the last 845450 shares, and we will divide the 50 BTC over the people that submitted those shares. The number 845450 is half of the current difficulty and will be automatically adjusted if the difficulty rises.
- This is more fair for cpu/low power miners: you will have profit from very fast blocks, even if you could not submit a share for that block.
- This is fair for irregular miners: if you only mine at night, you will ofcourse have less chance on finding a block, and only when your pc is actually mining during the finding of a block will you receive BTC's, but you will earn much more from a block when it falls, so in the end, statistically, you have more profits then with no poolhopping protection. Note that your income may fluctuate even more...
- This is fair for normal 24/7 miners, as they will get more, as the poolhoppers cannot run away with any BTC's...
- This is not pleasant for poolhoppers: they will get 0 on long blocks, and a block after a long block will not gain any decent profit anymore.
So when are we going to implement this change?
Soon
Why not a geometric or normalized system? We're already into the 6 million shares and even for some of us who are not habitual hoppers, the cost of operation means that we have to divest some mhash power elsewhere. Not to be given any reward for those shares isn't very fair either.
While at the same deterring hopping is good, at our current pool speed, getting some hoppers with high hashrates in at the beginning every now and then is useful too. With the proposed scheme, no hopper will hop here and over time, it would prolong future rounds especially if new miners are not convinced to join or return after this such long rounds. Maybe when the pool speed gets up into the 300~400GH/s speeds, then we can adjust it to fully PPLNS.
Since tripleming has the unique feature of a jackpot, why not further tweak it by only picking miners who contributed for the last difficulty/3 shares?
Just my 380Mh/s worth of thoughts
