MiningRigRentals.com, NiceHash.com, or any other rental site will work, and you can use any algorithm that ipoMiner supports depending what coin you want to mine: scrypt, X11, SHA256, or neoscrypt currently.

There was a problem with scoring of DNote blocks, thanks for notifying - it has been fixed now. DOGE is merged mined, so difficulty is very high as it competes with most scrypt mining power including LTC, etc. - no blocks of DOGE have been found on the pool since June (https://www.ipominer.com/stats?curr=doge).

No, it has not been added again since they restarted POW mining.

There was a web server outage today due to a disk failure. Mining / shares were not impacted. It has now been resolved.

I don't know why your AntMiner software would display that amount of "found blocks" for PPC mining, but it must be incorrect. The last block of PPC that was found on ipoMiner was on June 4. Beyond that, there is no plausible scenario where you could find 21 blocks of PPC in 2 days at 13.5TH/s. Mathematically, you are expected to find 1 block in ~5.5 days of mining PPC at current PPC difficulty. Further, the "best share" values shown in your screenshots are ~22M and ~79M, while block difficulty for PPC is ~1.5B.. so it is impossible to have solved a block with the highest share value you have submitted.

GoldBlocks (GB), MazaCoin (MZC), SysCoin (SYS), and Digibyte (DGB / DGB_S) will be removed from ipoMiner on June 1, 2017. Please withdraw those three coins prior to June 1 if you have a balance and want to keep them.

GoldBlocks just finished its POW mining period and cannot be mined now.

MazaCoin (MZC) was removed from Bittrex so it lacks liquidity for being able to use it for multiport mining.

SysCoin (SYS) has not been mined on ipoMiner for quite some time, since they changed the mining algorithms/merged mining last year.

Digibyte (DGB / DGB_S) recently implemented and activated Segwit, which requires stratum modifications to continue mining it and we are not currently planning on making them.

The following coins will be removed from ipoMiner on March 13, 2017 as of 23:59 EST:

- Dash (DRK)
- Digitalcoin (DGC, DGC_X, and DGC_S)
- MindCoin (MND)
- Titcoin (TIT)
- UFOcoin (UFO)

For most of those coins, they do not seem to have substantial ongoing development, have been removed from major exchanges, and are unlikely to be suitable for us to mine again soon.

Dash (DRK) is different with respect to those points than the rest, but its difficulty has generally been too high to make much sense for us to mine with our typical X11 pool hashrate in recent months. Blocks are only being found very rarely; for example, only four blocks in December and three in January. Additionally, the Dash wallet code changes fairly often which requires more maintenance work than makes sense for us with a coin we don't actually mine much.

Note that we remove coins from time to time to conserve resources and to discourage long-term storage of coins on ipoMiner. Please consider withdrawing coins to an exchange for trading or to a local wallet regularly in the future. Please withdraw your current balance of those coins before March 13, 2017 if you want to keep them.

CloudFlare just announced an issue (https://blog.cloudflare.com/incident-report-on-memory-leak-caused-by-cloudflare-parser-bug/). From the details they describe, it seems like it is unlikely that ipoMiner users will actually be affected, but it's certainly worth posting about.

The most likely potential window for information leaking at CloudFlare seems to be between February 13 and February 18, but it's possible the issue existed as far back as September 2016. I removed all session/login cached data as a precaution as of February 24 00:00 GMT, which just means you'll need to login to your account again the next time you visit the site regardless of when you last visited. It doesn't seem necessary to force every user to reset their ipoMiner password, but changing passwords is advisable if you want to be cautious.

Note that the CloudFlare issue impacts all sites using CloudFlare, which is a very large portion of the internet. Among many potentially significant sites, lots of cryptocurrency exchanges use CloudFlare, including Coinbase, Poloniex, and Bittrex. To be 100% certain of the security of your authentication data, you may want to update passwords on every site you use since it can be difficult to determine if a site uses CloudFlare or not.

Yes, and if the price of GMC was fairly volatile, it would make sense not to mine it because of the lag between mining and the likely chance of finding a block "soon" to receive a payout.


I looked into it a bit but didn't see any problem with GB or port 3649. I'll be out most of the day today but can check into it more later and let you know. It is probably easiest if you send an email to support@ipominer.com to follow up.

Use caution with the VCash pool - it has been mining on its own fork for 2+ days. Miningpoolhub is at VCash block 599895 currently while the rest of the network is at 600754:

GMC difficulty is high relative to our Scrypt multipool hashrate and we don't spend that much time mining it - no real problem.

Updated to v1.8.8, bring on POW!

I'm at 309701 here. New wallet looks good -- getting ready to resume POW mining 

Sorry about that - there is an issue with the DRK wallet code, where it becomes unresponsive when running its on-chain budgeting process. When it doesn't respond, the website's statistics updating jobs become locked. Anyway, it should be updating normally now. Feel free to email support@ipominer.com if you have any issues, too.

You earn coins when blocks are found. From your screenshots it looks like you're asking about DRK -- the last DRK block was found >2 days ago; when the next DRK block is found you'll get the appropriate portion of it according to how many shares you contributed.

It was the same issue with DASH - happens ~once a month. One of these days I will go into the DASH wallet code and see what the bug is; mostly I've been hoping they fix it themselves though. It happens whenever their mastersnodes budget funding voting process occurs.

Yes, no problem with mining. Today there was a problem with the DASH wallet failing to respond which caused the statistics caching to fail to process though. It should be resolved now.

Sorry about that -- there's a lower limit on what the PPC wallet can send, and people keep requesting very small withdrawals which the wallet fails to send and causes a backlog of other withdrawals. Should be fine now, unless you're the one that is trying to withdraw ~0.001 PPC.. in which case, it isn't going to work.
