What payout method does the pool use? We use PPL${n1}S (Pay Per Last $n1 Shares) PPL${n1}S means that when a block is found, the block reward is shared among the last $n1 shares that miners sent to the pool, up to when the block was found. The $n1 value the pool uses is $t times the network difficulty when the block is found - '$n'. How much of each block does the pool reward? Transaction fees are included in the miner reward. Pool fee is 0.9% of the total. How do the payments work? The $n means the pool rewards $t times the expected number of shares, each time a block is found. So each share will be paid appoximately $ot of it's expected value, in each block it gets a reward, but each share is also expected, on average, to be rewarded $t times in blocks found after the share is submitted to the pool. i.e. if pool luck was always 100% then each share is expected to be rewarded $t times. If pool luck is better than 100%, then the average share reward wil be better than $t times. If pool luck is lower than 100%, then the average share reward will be less than $t times. What's a shift? When your miner sends shares to the pool, the shares are not stored individually, but rather summarised into shifts. Shifts are ~50min or less in length, however, when we find any pool blocks the current shift ends early, at the point the block was found. A ckpool restart will also end the current shift and start a new one. So, what's the $n value? The current Bitcoin network value for $n1 is $nv and thus $n is $nv5 Bitcoin adjusts the $n1 value every 2016 blocks, which is about every 2 weeks. When a block is found, the reward process counts back shifts until the total share difficulty included is $n. Since shares are summaried into shifts, it will includes the full shift at the end of the range counting backwards, so it usually will be a bit more than $n. When are payments sent out? The block 'Status' must first reach '$bc' on the Blocks page, and then is flagged as '$bm', before the reward is distributed. The block reward is sent out manually soon after that. |
