REDUCING REWARD VARIANCE You do not have to mine at only one pool. In order to reduce your income variance, you should mine at multiple pool. As well as reducing variance, this will also help decentralize the network. Details in this post:

Attribute description
  • Hoppability: In hoppable pools, the attractiveness of submitting shares (in terms of expected return, variance and maturity time) varies based on the pool’s current state. Hoppers will take advantage of times of high attractiveness, leaving steady miners to suffer from more than the fair share of unattractive times. In hopping-proof pools, the expectation, variance and maturity time of the reward per share is always the same.
  • Share-variance: This is the variance (statistical deviation between the expected re- ward for a share and the actual reward) caused by the miner being too small or inter- mittent. Using a method with high share-variance does no harm to continuous large miners.
  • Pool-variance: This is the variance caused by the pool being too small. Using a method with high pool-variance does no harm to large pools.
  • Maturity time: This is the average time it takes to receive the due reward. High maturity time causes loss of the time value of money, and risk of the pool being discontinued before the rewards are received.
  • Operator risk: This is the risk the operator is taking in absorbing some of the pool’s variance. Operators of risky methods will require a relatively high fee as compensation, decreasing the expected earnings of participants.
  • Variance+risk: Mostly relevant for pools which can adjust variance and operator risk, this is their invariant total.
  • Variance+risk+maturity: Mostly relevant for pools which can adjust variance, risk and maturity time, this is their invariant total.
  • Complexity: The level of complexity in describing the method, implementing it and modeling its dynamics.
  • Instability: This is the probability of the pool’s collapse, and the severity of the event.
  • Author’s rating: The author’s opinion of the quality of the method, all things considered. 5 are the best methods, 1 is the worst.



Method description
  • Proportional: The block reward is distributed among miners in proportion to the number of shares they submitted in a round. The expected reward per share depends on the number of shares already submitted in the round, so hoppers will receive much more than their fair share and steady miners will earn much less. This is the worst reward system and must not be used.
  • PPS: Each share receives a fixed reward known in advance. This is the ultimate low- variance, low-maturity simple method, but has the highest risk for the operator, and hence lower expected returns than other methods and risk of collapse if not managed properly. It is currently only moderately attractive, but is the way of the future - it will be the most widely used method when the infrastructure to offer it with low fees is established.
  • slush’s method ([5]): Each share is rewarded with a score depending on when it was submitted (an exponential function of time), and block rewards are distributed among miners in the round in proportion to their score. It is historically the first method developed specifically to combat pool-hopping, though it is incomplete and some hopping is still possible. Contrary to a popular myth, the method is perfectly usable by intermittent miners and their long-term average returns won’t be affected. The variance for intermittent miners will be especially high, though.
  • Geometric method ([3]): This is a hopping-proof method based on a more accurate implementation of the principles set forth by slush’s method. Shares are rewarded with a score that decays exponentially as more shares are submitted. The operator takes a variable fee to maintain a steady-state history. The total variance in this method is high, though its distribution between the operator and miners is adjustable. PPS is a special case of this method where the operator takes all the variance.
  • PPLNS ([1]): Block rewards are distributed among the last shares, disregarding round boundaries. In the accurate implementation, the number of shares is deter- mined so that their total will be a specified quantity of score (where the score of a share is the inverse of the difficulty). Most pools use a naive implementation based on a fixed number of shares or a fixed multiple of the difficulty. The share-variance can be reduced at the cost of increased maturity time, but there is no way to decrease the long-term pool-variance. All implementations cannot be hopped using traditional methods. However, only the accurate implementation is hopping-proof against diffi- culty adjustments.
  • SMPPS: This method attempts to give shares the full PPS reward on a best-effort basis. However, when there is a backlog of due payments the maturity time is high. Hoppers can mine when the balance is positive and enjoy low-fee PPS, and leave when the balance is negative. The properties of stochastic processes guarantee that the negative balance will eventually become arbitrarily high, inevitably causing the collapse of the pool when it becomes unattractive to mine. This is exacerbated by the fact that any losses due to block withholding, invalid blocks and stale shares (if paid) cause the deficit to pile up.
  • ESMPPS ([6]): A refinement of SMPPS, where the least paid shares are prioritized. The total reward for a share converges to a steady-state ratio of the maximum long- term payment possible per share after losses. If this steady-state is accepted as the due expected reward, this keeps maturity time in check and prevents debt, measured up to the steady-state level, from piling up. However, the debt will still go arbitrarily high due to variance. The pool may survive this if the participants are loyal.
  • Double geometric method([2]): A hopping-proof hybrid between the geometric method and PPLNS, including the former and an exponential version of the latter as special cases. Shares decay exponentially with the number of future shares submitted and the number of blocks found. Round boundaries are crossed but not ignored. Maturity time, variance and operator risk are adjustable, with a low total invariant.

For a more comprehensive discussion of these methods, see [4].

Couple of things...

1) Why do you call multipool.us/cryptopros.com "p2pool proxy pools"?  They don't, as far as I know, contribute hash rate to the p2pool network.  The only p2pool proxy pool I can think of is OgNasty's "NastyPoP"... where he's got a ckpool instance on top of the p2pool framework.
2) P2Pool does indeed merge mine if the node operator configures it.  NMC, IXC, HUC, I0C, FSC, DVC, etc are all merge mined on p2pool.  Also, the fees are dependent upon the node operator as well.  It also can be configured to donate to the author of p2pool (forrestv).

Jonny's Pool - Mine with us and help us grow!  Support a pool that supports Bitcoin, not a hardware manufacturer's pockets!  No SPV cheats.  No empty blocks.

1. Multipool - I will move it to proportional I think it is a better fit there..it fits under proxy mining and proportional.. Cryptopros is on my short list ... I will delete it soon if it does not work

Community members or pool ops told us that the pools were p2pool nodes. If this isn't the case., that needs to be changed.

innerchaos: is multipool.us still proportional? If thought they were PPS? (can't access their site from work to check). If Multipool is still a proxy pool but *not* a p2pool proxy, then I'd list them under "proxy pools" at the end.

proxy and proportional for now.. I thought I was reading on their website that they offer proportional payouts.. I got sidetracked by the phone.

"Our modified proportional payout system means that you can be sure every share you submit will be paid. No shares are discarded without being paid. Our method is resistant to pool hoppers."

Weird. If they're a proxy, I can't see hoe they could use any reward other than PPS since they're not solving the blocks themselves. If you have time it might be an idea to email them for clarification.

It's a sort-of PPLNS. Unless I've misunderstood, it's a PPLNS with exponentially decaying share values.

Yea, I login and see they have a BTC Mining Pool currently at 1.223 PHs

I never saw thier name on the blockchain but according to them the last block they found was Block #363243

It's possible. Block #363243 sent the block reward to 1NY15MK947MLzmPUa2gL7UgyR8prLh2xfu, which had an average hashrate of ~ 2.8 Phps last week. It's labeled as "digitalbtc' (who own mintsy) at blocktrail.com and blockchain.info, but there's no proof of that offered.

Edit: do you have a link for their stats page?

Tricky. I wouldn't include anything that wasn't either provably correct or only from your own experience, or start up a thread that discusses your experiences with various pools.

I'd go further and say just include objective information. That table is all subjective stuff.

How about listing those pools that are churning out empty blocks & therefor not contributing to the Bitcoin Network?

We will continue do SPV mining despite the incident, and I think so will AntPool and BTC China.

Another very good reason people should not mine on Chinese pools.  This is EXTREMELY bad for the Bitcoin network.

It would help miners make a more ethical decision about what pool to use & also help decentralize the hash power away from the bigger pools who aren't towing the line  Wink
