[ANN][POOL] ipoMiner - Profitable multipool targeting new coins + merged mining!

[ipominer]

Hoes does the staking at SEED work? Do I need to have my wallet turned ON 24/7 in order to get maximum of it? Thanks.

My understanding is that you shouldn't need to have it open 24/7, until your first coins would be eligible to stake. But its probably best to ask the SeedCoin developers directly since their coin works a bit differently than a standard interest rate POS coin.

[ipominer]

SeedCoin has had mandatory/urgent updates recently, which I've applied, but there have been a few forks on its network. I have had to resync the blockchain once to get back onto the main blockchain after it forked.

It seems okay for now, but mine it at your own risk - it could fork again. I'm going to disable sending payouts for at least the next 8 hours, to make sure the network is stable and coins won't be lost on withdrawal.

Hi Ipominer,
check the ghost coin ann thread, apparently there is a problem in code, which means it did not finish POW after block 5000, and the coin is now disabled on Bittrex.
May be worth to remove from MP, as mining it may be risky, I`m going to work so don't have time to read about whole situation regarding ghost right now.

[ipominer]

GhostCoin has been removed from mining about 30 minutes ago. To clarify, the problem with it wasn't that it didn't finish its POW at block 5000, because only its POW blocks counted towards the POW block limit and there were about 50% POS blocks. The problem with the code is that they removed the check on PoW block reward amount, and then ran their own pool which allowed them to create larger than normal blocks.

Normally the network verifies the block amounts, but it wasn't being verified because they removed the check for it in the code. This is a similar exploit mechanism as USBCoin used, although the codebase is not the same so it wasn't readily detected. They also put up a block explorer which intentionally hid their blocks that were mined over the standard block reward.

Ack! My seedcoin disappeared! Did we fork or something? Had it set to move to wallet at .0041 but it just vanished and got no withdrawal confirm. Looks like unconfirmed is just vanishing now, maybe we are forked. WTF!

I don't see any issues with SeedCoin currently. There had been forks previously yesterday and the day before, but nothing that seemed to impact us heavily. If you want to hop on IRC to explain the issue in real time, we're in ##ipominer on Freenode -- or please email support@ipominer.com.

[Jerubbaal75]

It looks like its working now & everything's fine. Sorry for panicking. I should have waited a bit before posting.

I do not know if it would be possible but could you add a feature to exclude different coins on the multi port. We would check a box and when the pool switched coins if it was going to an excluded coin it would stay on the last coin or move to the next most profitable.

I like the idea, but unfortunately it isn't possible without redesigning our entire stratum architecture from scratch.

One thing to note is that not all coins for an algorithm are enabled on its' multiport. I hand select which coins are enabled for multiport mining, and take a variety of factors into consideration including buy support, price trends, average difficulty, etc. For example, there's not much value in mining a coin that has a declining price trend and takes a long time for blocks to mature, or a coin with high difficulty since switching on/off of it will likely produce very few blocks.

(Note that most multipools do not do perform the same level of research and hand selection of coins for multiports - its all about a block's profitability for them, which is problematic since the price of a coin at the time of mining and time of selling typically varies substantially.)

If there is a particular coin you're trying to avoid right now, I'm happy to consider removing it from multiport mining if there's a good reason.

[jimlite]

That was a great response. I am glad you are trying to maximize profits for regular miners. Now all we need is for you to auto convert them to btc for us, so we won't make mistakes of selling at the wrong time or price

If you haven't been following GhostCoin closely, here's a quick update on the situation:

There was a wallet/blockchain level exploit which allowed people to mine blocks of any value, including blocks of up to 10M coins. (Not on ipoMiner, but on other pools).

The coin developers have now rolled back the blockchain to block 7629, which was before the majority of the exploited blocks occurred, and the coin is now POS-only with no more POW blocks being able to be mined.

We mined 17 blocks after the rollback block: 7639, 7669, 7776, 7816, 7838, 7855, 7901, 7958, 7972, 8060, 8088, 8310, 8317, 8342, 8362, 8422, 8425. You may see a negative GHOST balance currently because payouts for those blocks have been removed.

I am now going through the painful process of fully auditing transactions that we sent out vs. what exists on the current blockchain. I'll post an update once that has been completed.

@ipominer, if it is of any further assistance please post in the GhostCoin thread a donation address that can be used if possible to compensate those miners affected with a negative balance. If you have any issues please address them in the thread and we will try to provide assistance as promptly as possible.

Thank you.

Thanks for the update GhostCoinDev. I'm still working on auditing balances against outgoing transactions to see which of them are actually present on the current blockchain. I'll be in touch when I've finished that.

[Phantomofheat]

The two coins I would like to see removed XHC no markets are open for this coin and they are on the third set of developers. The second DPC but it looks like we are not mining that as of now.

[ipominer]

Right. I removed DPC from the multiport when Bittrex removed it due to wallet problems.

On X13, unfortunately there's no good coins to mine currently. I added GLOW and it was the multiport coin 100% of the time while it was mineable, but its POW phase has ended now.

[ipominer]

I have completed a full audit of our GhostCoin mined blocks and withdrawals now, and payouts for GHOST have been re-enabled. Mined blocks that are not on the current blockchain have been removed from balances, and withdrawal transactions that are not on the current blockchain have been added back into balances.

All users with negative GHOST balances have had their balances zeroed out, which was compensated for with my own personal funds.

Withdrawals for NautilusCoin have also been re-enabled following their new wallet release and fork.

Hi, is there a problem with the DOPE direct port 3470 (scrypt) or is it just me?

[ipominer]

Hi, is there a problem with the DOPE direct port 3470 (scrypt) or is it just me?

There were two stratum processes running on the same port internally for DOPE behind our load balancer. It has been fixed and should be working now.

[ipominer]

HashX payouts for the payout week of October 10 - October 16 have been made.

This week had an average daily net profit of 0.00034100 BTC per Mh, which comes in at a +17.37% premium to a baseline of LTCGear qASIC shares.

For a comparison against ZenPool: ZenPool costs 250% more ($19.95/Mh vs. HashX at $7.99/Mh), but only pays out 2.6% more (0.00035 BTC/Mh/day today).

[ipominer]

Two new coins were added today -- OCC and SPARK:

OcultCoin (OCC) was added on the X13 multiport.

SparkCoin (SPARK) was added on the X11 multiport as a new coin override, and on direct port 3634.
