Does MMC still use Kimoto Gravity Well?

I was updating the MMC page on The CPU Coin List. The first post and MMC website show KGW still in use despite the known issue.

Can you point to the issue page ?

I'd like to invite everybody here to come track my progress as I train for the Devil Mountain ultramarathon in August. MemoryCoin is sponsoring me, which is just another one of the cool things this coin is capable of due to its paid leadership team.

I'm going to be posting regular updates on my progress over at the new MMC-Square forum here: https://www.mmc-square.com/biophils-race-for-success/29/

Hey guys - I have a question for you all and for the dev team. Our MMC wallet did something REALLY weird yesterday.

I run AllCrypt.com, an exchange where MMC is traded. Users make addresses and each address in the wallet is attached to a user ID (via the account system in the wallet).

We received a deposit of 880 MMC yesterday to an address that we never made, that was not attached to a user. I assumed someone out there typo'ed an address and mis-sent us the MMC by mistake. I'd look into it later.

This morning I start getting errors that a user is trying to withdraw 100 MMC but it's failing because he does not have enough in his wallet. This sometimes happens with some odd orders where a rounding issue makes a wallet insolvent by 1 satoshi. I fix it, find the code error, and patch it up.

But this user's balance was at -780 MMC. Something that should not be possible.

So I looked at his transactions - and at the very same time he did a 120 MMC withdrawal yesterday, he ALSO did a 880.018 withdrawal to that weird address we saw the deposit enter yesterday.

NOTHING in our logs show that happening. NOTHING in our logs show that address. It's not a change address - those are not seen as deposits. A .07 MMC fee was paid for the transfer. Fees are not paid for change. There was no withdrawal initiated on our side for that amount.

Why did the MMC wallet randomly send 880 MMC from an account that did not even have 880 MMC, to an address in the same wallet?

Seriously concerning me. That should NOT happen.

But actually... after I wrote all that it looks like that MIGHT have been change...? But why was the change recorded as a send? With a paid fee?

The user withdrew 120 MMC, and the source seems to be from an address that had a 1000 MMC deposit - so the 880 change makes sense, but why was the change "sent" with a fee that entered the blockchain? For bitcoin, you can see the change transactions when looking at blockchain.info but NORMAL 'listtransactions' in the bitcoind RPC do not show change.

This is showing as an ACTUAL send - like an intentional send from an address.

Unfortunately, both block explorers are down so I cant even show the transactions.

AAIGH. Ok so I posted that.

I then moved the 880 into that users account so he could withdraw the failed 100 from last night.

It then, for some frigging reason, withdrew the 100 as planned, and then did another send of 76.018 with a fee of .07 to some new address we've never seen before.

Leaving his account at -74.09 MMC

With some deposit of 76.018 to another 'mystery' account.

Why the hell is MMC sending change through the blockchain with a fee? Thats an accounting NIGHTMARE.

I'm going to have some of our officers look at it. Unfortunately you have an issue that is actually quite confusing to read. Please make these actions are more precise and detailed so that we can detect and repair the issue in the wallet.

I suggest you find a different way to handle all transactions or silently pause all withdrawal and deposits by having a backlog to be processed once the issue is fixed.

I will have to contact our Chief Network Officer, who is co-serving as our Chief Technical Officer while the spot is unoccupied by a real candidate. We have voted in a Chief Marketing Officer (2) to replace our previous Chief Technical Officer's position, and we are still focusing our priority in the marketing sect. Fortunately he can look for these technical issues, but the network problem shouldn't be an issue as we see all other MMC exchanges have implemented their transactions in a way that can round up their transaction fees.


If you can, please rephrase all your actions and results in a very objective manner so that even the community can take a look at it.

Can you provide all the transaction ID so that we can check in the blockchain ?

This is a known issue. To make voting easier FreeTrade decided to use a one address per wallet approach, which unfortunately breaks the account management as explained in https://en.bitcoin.it/wiki/Accounts_explained

To fix this, start your memorycoind with command line option -multiaddress

The following outlines your problem:

Code:
memorycoind getaccountaddress abc
### send 5 MMC to that address
memorycoind listaccounts
{
    "" : 0.00000000,
    "abc" : 5.00000000
}
memorycoind move abc def 2.15
memorycoind listaccounts
{
    "" : 0.00000000,
    "abc" : 2.85000000,
    "def" : 2.15000000
}
memorycoind sendfrom abc <some other MMC address not on this memorycoind> 2
memorycoind listaccounts
{
    "" : 2.95999007,
    "abc" : -2.15000000,
    "def" : 2.15000000
}

This is how it should work:
----------------------------------------------------------------------------------
primecoind getaccountaddress abc
### send 2.4 XPM to that address
primecoind listaccounts
{
    "" : 0.00000000,
    "abc" : 2.40000000
}
primecoind move abc def 1.1
primecoind listaccounts
{
    "" : 0.00000000,
    "abc" : 1.30000000,
    "def" : 1.10000000
}
primecoind sendfrom abc <some other XPM address not on this primecoind> 1
primecoind listaccounts
{
    "" : 0.00000000,
    "abc" : 0.29000000,
    "def" : 1.10000000
}

There will be a hard-fork set at Block 35720 or 14 days from now. This update fixes KGW's Time-Warp Bug.

Please update your clients accordingly before this period.
Update your wallet here

The github will be updated shortly.
We will be updating the MMC Source before this fork.

Follow us on Twitter!

Memorycoin has been put back on the list because KGW has been patched.

Would someone point me to some GPU hashrate info so I may calculate GPU Advantage?

My wallet won't sync anymore. It has multiple connections and shows the green checkmark but is stuck.

I'm using the up-to-date 0.8.583 wallet

got 35752 blocks left - this value doesn't change a bit.

How do I fix this?

Only in MMC-Square forum I think ( registration needed)

"We are just fools. We insanely believe that we can replace one politician with another and something will really change. The ONLY possible way to achieve change is to change the very system of how government functions. Until we are prepared to do that, suck it up for your future belongs to the madness and corruption of politicians."
