Reward types & explanation:

  • PPS - Pay Per Share. Each submitted share is worth certain amount of BC. Since finding a block requires <current difficulty> shares on average, a PPS method with 0% fee would be 50 BTC divided by <current difficulty>. It is risky for pool operators, hence the fee is highest.
  • SMPPS - Shared Maximum Pay Per Share. Like Pay Per Share, but never pays more than the pool earns. [1]
  • ESMPPS - Equalized Shared Maximum Pay Per Share. Like SMPPS, but equalizes payments fairly among all those who are owed. [2]
  • CPPSRB - Capped Pay Per Share with Recent Backpay.
  • Prop. - Proportional. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found.
  • PPLNS - Pay Per Last N Shares. Similar to proportional, but instead of looking at the number of shares in the round, instead looks at the last N shares, regardless of round boundaries.
  • Score - Score based system: a proportional reward, but weighed by time submitted. Each submitted share is worth more in the function of time t since start of current round. For each share score is updated by: score += exp(t/C). This makes later shares worth much more than earlier shares, thus the miner's score quickly diminishes when they stop mining on the pool. Rewards are calculated proportionally to scores (and not to shares). (at slush's pool C=300 seconds, and every hour scores are normalized)

  1. ↑ Note that pool hashrate is largely irrelevant but can be seen as a popularity measurement. Note however that it is a theoretical security issue if one pool gains above 50% of the total computational power of the network, thus consider joining a pool based on other metrics.
  2. ↑ Merged mining allows miners to mine on multiple block chains at the same time with the same hashing.
  3. ↑ ABCPool also rewards stale shares
  4. ↑ 4.0 4.1 4.2 4.3 4.4 4.5 4.6 4.7 Donations are possible
  5. ↑ 5.0 5.1 Proprietary-protocol pools (BitPenny and p2pool) provide JSON-RPC to miners locally.
  6. ↑ Fee is a payout fee. Instant payout: 2%. Scheduled payout (each night): 1%
  7. ↑ People are donating to P2Pool miners to encourage people to use it. The P2Pool author also accepts optional donations.
  8. ↑ Triplemining's 1% fee is redistributed using a weekly jackpot
