Reward types & explanation:
- PPS - Pay Per Share. Each submitted share is worth certain amount of BTC. 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.
- Prop. - Proportional. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found. This method is vulnerable to pool swapping cheat, where a worker would swap to another pool, if this one didn't find a block quickly. Then he would have extra profit on fast rounds, and normal profit on long rounds (because he would be mining on another pool by then). To mitigate this problem pools must introduce extra fees, and hide statistics, so that it is unknown when a block is found.
- MaxPPS - Maximum Pay Per Share. Like Proportional, but with a protection against pool swapping, which gives it some PPS-like characteristics. [1]
- Score - Score based system, the most advanced one. It is a proportional reward, but it is impossible to cheat as described above. 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 more than earlier shares, thus swapping away to another pool on longer rounds makes the cheater's score to quickly diminish. Rewards are calculated proportionally to scores (and not to shares). Statistics can be shown "live" without fear. The score based method is perfect for 24/7 miners. (at slush's pool C=300 seconds, and every hour scores are normalized)

- ↑ Hashrate is given in gigahash/second.
- ↑ 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.
- ↑ Auditing can be accomplished by third-parties if the pool publishes proofs-of-work for every share.
- ↑ 4.0 4.1 4.2 4.3 Donations are possible
- ↑ Donations are possible to unlock features
- ↑ Access to Eligius proofs-of-work is available on request.
