No frills, no fuss ZERO FEE anonymous SPLNS bitcoin mining for everyone

No registration required, coinbase generation, no pool op wallets

Configuration:

Just point your miner to one of:
Code:
pool.ckpool.org:3333
pool.ckpool.org:443
If in Europe use one of:
Code:
depool.ckpool.org:3333
depool.ckpool.org:443
If in mainland China use:
Code:
cn.ckpool.org:443

Set your username to your btcaddress with any or even no worker extension, and any password.
eg:
Code:
cgminer -o stratum+tcp://pool.ckpool.org:3333 -u 1PKN98VN2z5gwSGZvGKS2bj8aADZBkyhkZ.0 -p x
If you enter an invalid address you will be rejected

SPLNS

SPLNS stands for Score Per Last N Shares. Score refers to the fact that share value is weighted by the difficulty of the share found.
Last N Shares refers to the fact that the score is a rolling score based on N shares where N means 5 x the current difficulty.
The rolling average is weighted according to when the shares were found - the more recent shares are the more they are worth.

Features of SPLNS:

Hop proof - the system cannot be gamed to earn more by hopping on and off during lucky blocks.
Short "ramp up time" compared to PPLNS - rewards more rapidly rise to stable levels when you first start hashing.
Long "ramp down time" - you are still entitled to rewards for a very long period which is pool hashrate dependant rather than time dependent so you don't quickly "fall off" and earn nothing when you stop mining. Additionally this helps minimise variance for intermittent miners.
Lucky rewards - since shares are weighted by the difficulty of the share found, if you are a small miner that has a handful of lucky high diff shares, you can earn significantly more, capped at current network difficulty.
Block finder rewards - as per lucky rewards, a large share weight is attached to block finds (but is applied to the next block reward since user rewards are included in the existing unsolved block reward.) The sooner the next block is found, the higher the block finder reward is.
Malicious & faulty miner disincentives - since shares are rewarded according to the difficulty of the share found, malicious miners that withhold block solves, or faulty hardware that doesn't produce high diff shares will have substantially less reward than on any other pay scheme or pool.

SPLNS calculation is done on the fly and updated every minute based as a product of HERP DERP.
Herp stands for Hash Extracted Rate Product - where each share is worth sqrt(MIN(share diff, network_diff) / work_diff) * work_diff / 2
Derp stands for Difficulty Extrapolated Reward Payment - where the reward equals the user's herp divided by the pool's herp i.e. it is the expected reward should a block be found now.
The pool's Herp is simply added until it reaches 5 * network difficulty. After that it is biased every minute by scaling existing herp down to add the latest minute's herp and all users' herp is adjusted by the same scale the pool's was.

Additional and/or unique ckpool.org features:

Accurate statistics by the minute - while the statistics displayed at ckpool.org are rudimentary, they are updated by the minute and include accurate estimates of hash rate, herp and derp - which translates into an accurate estimate of payout should a block be solved.
Luck estimates - as the difficulty of each share is calculated into the user's herp, it is compared to an equivalent 'last N share' calculation to determine the miner's overall luck. This is done on a per worker and per user basis and displayed in the stats.The larger the miner and the longer they mine, the closer to 1 their luck will be while small miners may have much more variation.
Coinbase generation - Block solve reward is distributed directly from the block to each user, meaning each user gets a 'mined' transaction directly into their wallet as soon as the block is solved so there is no wait to get paid and no pool wallet storing user's rewards. Rewards will be considered 'immature' by bitcoin rules so will be unspendable until 100 network confirmations have passed.
Interleaved rewards - Each time a block is solved, the top 100 miners will receive a payout while 50 of the remaining smaller miners will receive a payout. Rewards will alternate between the smaller miners according to who has waited the longest for a payout. Rewards accumulate from blocks worked on even if miners are not scheduled for a payout with that block. This is done to minimise the size of the coinbase transaction to minimise latency, maximise mining hardware compatibility, and to make sure miners don't receive many small payouts which would lead to much larger fees when spending their reward.
Micropayments - payments below the dust threshold at block solve time will add to the user's herp for the next block. Once a miner's reward on successive blocks is greater than the dust threshold they will join other users with interleaved payouts.
Blocks are always as full as network congestion demands - ckpool never mines empty or light blocks and yet is still extremely fast at getting new work out to miners on block changes to minimise wasted work and decrease orphan risk.
Rapid propagation of blocks thanks to high speed low latency connections across a network of bitcoin nodes to further decrease orphan risk.
Shares all transaction fees with miners - transaction fees account for a significant portion of mining reward now and as ckpool.org always mines blocks full of transactions the extra rewards can be substantial.
Massively scalable - ckpool can handle extremely large amounts of miners without detriment to performance.

FAQ

Q: Should I use different usernames for each of my miners?
A: You are much better off consolidating all your workers to use the same username and different workernames. The reason is each different user will get a separate reward transaction at block find and each transaction will attract its own fee to spend at a later date, so you'll end up spending less fees if you just use the one username. Additionally if you have multiple small miners (eg. USB sticks), you may never get over the dust threshold if each miners to a separate address.

Q: What is the dust threshold?
A: 5460 satoshi or 0.0000546 BTC. Once enough herp has been amassed to create this much derp, miners will enter the payout queue.

Q: Are there any restrictions on hardware?
A: Only ASIC miners are allowed. Only mining hardware/software that is faulty or malicious and cannot mine high diff shares or has some/all blocks withheld that you are conscious of is not allowed - using such hardware will lead to substantially decreased rewards.

While there is some weight to the "v1 bad luck" claim, one must realize that it would take months of v1s pulling 200+% on "that" pool in order to reach 100% on that pool (due to deficits from rigs that both left that pool and rigs that switched to v2 on that pool); so, in reality, there's no reason for any pool to "ban" v1s. It's hard for rigs that don't exist to raise past stats from when they did exist.  Undecided

Well, I pointed my gimpy R4 batch-6 (only 1 board working) at the pool last night and it's running just fine there at the same speed KanoPool reports which is 4.8THs. Considering chips & firmware are pert-near identical, s9's should be fine. He's certainly made no comment as to what can and cannot be ran, if anything, the idea is for the pool to accept all miners no matter how fast or slow, big or little.

Would there be any advantage if you have multiple workers to have each one on it's own BTC address?  or would it all work out to be the same payout.
If you ever want the coins to go to the same addy (i.e., cold storage, exchange, etc), then you'd want to use just 1 because multiples would cost you more fees to consolidate. Aside from that, it's all the same.

If you have to ask "why?", you wouldn`t understand my answer.

If I read it correct:
Malicious & faulty miner disincentives - since shares are rewarded according to the difficulty of the share found, malicious miners that withhold block solves, or faulty hardware that doesn't produce high diff shares will have substantially less reward than on any other pay scheme or pool.

so if your Miner is odd, you get payed less.

Btw, any restrictions on S9 v1 to mine here ?

No restrictions. As the front page says; all ASICs are welcome. If your stats are showing your luck converging to 1, I wouldn't worry, but I haven't had mathematical proof that the luck estimate is spot on yet.

Would there be any advantage if you have multiple workers to have each one on it's own BTC address?  or would it all work out to be the same payout.

No, there's a disadvantage. I highly recommend multiple workers use different worker names but the same username. The reason is each payout will end up being a transaction in its own right, and spending rewards will end up requiring more transaction fees. Additionally if you have multiple small miners (eg. usb stick), you may never get over the dust threshold if you split them up. I should add this to the faq... but there haven't been hardly any questions yet so there aren't any frequently asked questions  Wink

Added the first FAQs to the top post in anticipation of them being frequently asked.

Just means your miner has switched to a new diff too early on the instructions from the pool. In 30 seconds it would go away.
