We're experiencing some stability issues at the moment. We're working on resolving them.
UPDATE: Stability issues have been resolved.

NEWS: Historical performance available!
We've been hard at work these days on providing you with additional stats. And we're glad to say: They're here! This feature is enabled for everyone that donates 1.5% or more. If that's you, you may now view your performance over the past two weeks. Click on 'Stats', then 'history'. The hashrate includes valids and stales, but not invalids. In time we plan to display valid, stale and invalid shares seperately so you can have even more insight into you performance.

Aside: this upgrade is the reason the cron jobs went down. We've introduced memcached to cache the query for this graph, and there was a dependency missing.

Happy mining!
MC

NEWS: Payout history added!
You can now review all past payouts through the stats section. Payouts appear there as soon as they have been initiated. Please be aware that it may take up to an hour or more for the Bitcoin network to include a transaction in a block.

Thanks kwaak and rTech, that's exactly what we're going for: no bonusses, sweepstakes, give-aways, or complicated reward mechanisms at ABCPool. That only distracts from what's really important for a mining pool. We concentrate our efforts to give you a reliable no-frills service with consistent and transparant rewards that you can trust. People looking for excitement, please go somewhere else

Evidently! Big trees are not immune however.

That's quite a scary story you've got there right before bedtime But it's a nice metaphor.

Also: A big tree attracts the woodsman's axe..

Thanks for your input. We do not have such plans currently. What purpose would that data serve? We pay per share, and current round shares has no effect on the amount you will earn. On the other hand, one may argue that you can never have enough stats

Frankly, we don't keep track of current round shares in realtime. The numbers can be pieced together from the database after the fact, but that's a manual thing currently. I think publishing those numbers would only confuse people, since they are irrelevant to income.

We do still have plans for more stats in the stats section, such as 24-hour averages. Behind the scenes we have been working on aggregating older mining data periodically, because the database is growing ever faster. Once we have those aggregated sharecounts worked out completely we'll start reporting on it.

In the mean time, hold on please

With a couple of large pools down at the moment, this is an excellent opportunity to try out ABCPool for a while!

Get stable payouts due to the 0% fee PPS, and you even get paid for stale shares!

Once the other pools are back online, you are of course welcome to stay anyway!

Registration and configuration is the same as you are used to at other pools.

Thanks,
Your friends at ABCPool

NEWS: NTime-Roll support slashes stale and invalid rates!
Abcpool has been running quite stable for a while now, and judging from the forum posts most people are mining with us without any issues.

Since scaling up our systems a few weeks back we've worked on an area that affects both performance and earnings: NTime-Roll support. This behavior ensures less system load and even quicker response times, especially when it matters most: when the countless Long Pollers trigger all at once. We've been watching the stale and invalid rates since we deployed this new version several hours ago, and we are pleasantly surprised the rates have dramatically improved:

Old stale rate: ~0.2% - ~0.6%
Old invalid rate: ~0.3% - ~0.8%
New stale rate: ~0.06%
New invalid rate: ~0.23%

That's right: on average, our members are now generating bitcoins with 0%-fee for 99.77% of their submitted shares. That's a number that is certainly among the best any pool has to offer, if not the best.

Thanks for your continued support, and happy mining everyone!

MC

NB: If you are experiencing invalid rates higher than 0.5%, please make sure you are running the latest version of your miner software.

NEWS: pool stats API

While we were at it, we added a simpel pool stats API at http://www.abcpool.co/api.php. We also changed the user stats API slightly so it creates better JSON.

Welcome to all stranded users coming in from Arsbitcoin, Bitcoin.cz, and Simplecoin! (these pools are currently failing..)

MacT just notified us that he was not getting automatic payments anymore. Automatic payments were disabled during migration, but we never enabled them after we were done; we simply forgot! They are enabled now, and should be functioning normally. That means any (back)payments will occur at the normal time, 11:00 UTC.

Thanks to MacT for letting us know about this.

50 characters is now the maximum password length, and you will get a notice when you go over that during regisration or pw change.

Thanks for your kind words and your continued donation. It is much appreciated!

Dear miners,

ABCPool is migrating to a new server in a few minutes, which is expected to cause ca. 2-5 minutes of downtime.

MC

Update: Migration was succesfully completed!

Cronjob was stuck; stats should be up to speed within a few minutes.

We hoped to have it ready by now, but we haven't gotten around to it yet. It's still on our agenda!

We have indeed had intermittent service disturbances earlier today. Everything should be back to normal now.

We have temporarily opened registration to allow several more users to discover ABCPool!
