We have just lowered the ABCPool.co fee-boundary for both automatic and instant withdrawal to 0.2 BTC. That means you can now enjoy your rewards even sooner!

Other pools currently charge 10%

Not true, rfcpool.com only charge 7% Smiley
It could be that they charge 7%. But their site does not list that number anywhere as far as I can tell. The price per share they mention seems out of date given the current difficulty. Their price does not translate to a 7% fee when you do the math (at the moment of writing).

In our opinion pools should be as transparant as possible about mining rewards, that's why we provide the exact calculation of our rewards in our faq.

Anyway, our 2% is a lot less than their purported 7% fee Smiley

We noticed earlier today that under certain conditions, stale shares would incorrectly be labeled as 'invalid shares'. These conditions are now properly handled for future shares. This matters to our miners since we pay for stale shares, but not for invalid shares.

We did our first payouts today! To make it easy for our miners we have both automatic and instant payout.

That's good, since we recently found out what happens when people leave their entire wallet on an EC2 instance!


searched and searched but somehow i seem to have missed this event you are referring to... can anyone point me to the incident sirky is referring to?

he speaks about the www.bitomat.pl accident:

This is correct. EC2 is not persistant!!!!!

And you are welcome MintCondition!

I am throwing some hashes at you.
Thanks for the hashes; you're chugging along nicely! As you can see your current stale rate is below 0.2% now, and those stale shares are included in your balance.

Our buffer is 'considerable', although we store most of it offsite as a security precaution.

That's good, since we recently found out what happens when people leave their entire wallet on an EC2 instance!

Anyway, I think my accepted shares are way to high, as are my stales. I should be around 700/0, not 9000/20 Smiley

My rewards seem about right though Smiley
I'm investigating it; we're seeing some other suspicious numbers too.

UPDATE: seems like some stuff is counted multiple times before being moved off to better places. The good news is reward calculation seems unaffected, but reported valid/stale/invalid counts are way off. We will probably have to reset those counts for our current users after this issue has been solved. Your balance will remain in place in that case.
The issue has been resolved. In the shares processing pipeline, some shares were sent back to a previous step. That caused them to be counted again when the next batch processing job executed. After deploying the fix, We've reset all share counts accumulated until now. This issue did not affect rewards; they were always right. Therefore, rewards have not been adjusted due to this issue.

Sirky, thanks for pointing out this issue!

Just out of curiosity, what sort of BTC buffer do you have? At 2%, your risk of ruin (mathematically speaking) is probably pretty high unless you have a lot of BTC.

How much are you planning on charging for a fee after the introduction period?
We have no plans to stop the introductory period/fee. If we ever increase the fee, we will post it on the site and the forum at least 4 days in advance. We can't say at this moment what the fee would look like in that case: We'll need to run the numbers when it comes to that.

@Burp: Lowering the payout minimum is on our agenda. We'll have to review the tx-fee implications before we do that, so it will probably be done later this week.

Can you reduce automatic payout to 0.1?

We've just opened our site to everyone for registration. We'll probably be accepting about a dozen users at this moment. That way we can provide the best service while we iron out any wrinkles in our pool.

Thanks for your concern sirky! These are exactly the things that make operating a PPS pool a bit more challenging.

The malicious/buggy type of stales that you mention have certain telltale properties. These make it possible to distinguish between them and honest stales. We compensate all honest stales. Honest stales are the result of a delay in long polling and normal network round trip times.

* We pay for Stale Shares: up to 3% extra income; because we think a pool should be responsible for delivering new work to you in time!


Be careful. There are people who will try to game this. I know other pools have seen people try to do really sneaky stuff, like submitting the same work several times, submitting the same work over several miners (ie if any miner finds a share, all workers submit it), and stuff like that.

Also, there are miners out there (cgminer) that, even if you are offline, will continue mining for the last known block. You don't want someone to just connect every hour to upload mostly useless work that you pay them for.

Best of luck with your pool though!
