Reward System: Hybrid PPS (#10)

Summary of PPS:

  • You get paid for each submitted share accepted by the pool regardless when or if the pool finds a block.
  • If pool finds less blocks than statistically expected, the pool operator pays the rewards from its pocket.
  • If pool finds more blocks than statistically expected, the pool operator takes the extra profit.
  • All the risk is on pool operator's side, because users always get money for what they submitted.

Motivation for Hybrid PPS, explanation:

  • While PPS is really simple and understandable reward system it is too risky for smaller pools. The probability of loosing too much and being forced to close the pool is too high.
  • One option how to manage the risk is to put pool fee up (this was the case for some pools in history) - We don't want to go this way.
  • Second option is to pay let's say 85% of shares immediately by PPS system and for the rest use current system: continuous scoring.
  • ... TBD: Describe money buffer for the second stage.


  • Most of the shares will be paid as PPS, immediately and with no user risk.
  • All blocks would be paid to users fully even for fast rounds.
  • The risk of pool bankruptcy will stay low.
  • Pool fee will stay low.

Comments & Updates

  • I think the current reward system is the best. It is the most fair, the most resistent against cheating and the most interesting.

  • I like the idea. My machines are not on all the time, and this would make it more worthwhile to contribute to the pool more often.

  • I like the idea. My miners are solar powered and only run during daylight hours. With the existing payment system I earn 25% less than I do at PPS pools where I am paid for actual contribution when miners are running.

  • Like the second option on the second summary. It balances the risk with the pool and miners. The risk falls on the miners most of the time & the pool statistical would break even or greater, while the miners could get paid much more quickly.

  • Good Idea, but it can be useful that we can chose between payments systems. If you look the current biggest pool, it's a pps payment mode with 4% (theorical because it's rejects more block than slush's pool, in reality fee are about 5.4% on my miners....) I think the best solution is to have a select box to choose payment option (for exemple PPS with 6% fees, pplns with fee 2.5%... Score with fee 2% ...). So every miners can choose his prefered payment system but work's on slush pool who have a good reliability and is very efficient. I think Slush have the best dashboard and a good pool, but score payment mode satisfies only the bitcoin purists, the others miners goes elsewhere ... And the purist are not many! Thank you

  • the score system sets slush apart from the other pools, sence its what makes slush pool slush pool i doubt its going to change, i vehemently disprove this but no votes
