Delist Notice: Signatum
As the vast majority of Signatum customers will be aware, there have been recent issues with this coin, which has led to us putting it in the delisting queue. Signatum is currently scheduled to be delisted on 20 Oct 2017. Read on for the reasons why this has been deemed our best course of action at this time.

The combination of us having 18,000 addresses and users mining directly to our addresses caused there to be over a million small inputs. This caused the wallet to irreparably break while syncing. We attempted to resolve this many times, using different distros and hardware configurations, however this did not work. If we synced the blockchain first, then imported the keys, it would start importing 5-10 keys / second, however this rate drops to about 1 key every 3-4 seconds after ~15k. After a week of importing keys on several instances the wallets corrupted and crashed every time. We also tried importing the keys first then syncing the blockchain, in this case it synced back to around 19th August and then also crashed and corrupted.

We have determined this to be likely due to the leveldb library used within the coin which is extremely out of date. It is the same library used in many other coins, however most use a much more up to date version.
This is why the Signatum wallet had been in maintenance for around the last month, while we have been constantly attempting to work with it. During this time, we had a Signatum team member visit our office in person and found no issues with our implementation of Signatum, and observe the sync issues. We have also been in constant communication with a Signatum team member informing of what was happening throughout and were told by him that he was informing the rest of their team.

To finally resolve this, we have managed to set up 8 separate wallets and imported 1/8 of the overall keys into each of these. We then had to move transactions around to consolidate the tiny inputs. This is a terribly painful process and not scalable.

FYI we are currently having to move coins from the 8 wallets to 1 consolidated wallet to process withdrawals. Once this process is complete, we will then scan the 8 wallets for any missing deposits, so anyone that has made deposits while it has been in maintenance will have to wait until this before their deposits show up so they can withdraw again.(edited)
The reason we are now closing the markets is that the Signatum community and now the core Signatum team have blamed us for this issue and are threatening us with litigation, when the issue is purely with the Signatum wallet and out of date codebase. The dev does not seem able or willing to fix the issues with their code. We have put in a very significant amount of time trying to get this up and running so our users can use their coins. However, it is not our responsibility to work with the Signatum codebase (or any other coin) to fix their problems any further, we've already gone well beyond what we should be doing to resolve this.

Some users have been comparing us to other exchanges and asking why they don't have a similar problem. We have a significantly higher number of transactions than the other exchanges that currently list this coin. They will run into similar issues when they reach a more significant level of transactions. The problem with Signatum codebase is provable and replicable. They need to fix this or this will happen again wherever Signatum ends up.

Signatum now appears to also be threatening Cryptopia with legal action (via twitter) and accusing Cryptopia of not knowing how to use wallets. We run and maintain literally many hundreds of wallets. Signatum built just 1 wallet by copying very old code from elsewhere and don't seem able or willing to update it to something that actually works at scale. Draw your own conclusions, and if you back Signatum after all this good luck to you.

Regardless of where the fault lies, a major exchange has now put this out there about SIGT. The SIGT team is going to have to fix the problems described should they exist, or make some other changes if they don't. Whatever is done needs to be sold to people as a faster & more efficient SIGT. They have to do something and make it very public they did something in order to rebuild confidence and move beyond this.

Is this true that signatum is not scalable? That they are using an out if date codebase? This makes me nervous for the long term if this is true

It is already Final.

SIGT is to be Delisted @ Cryptopia especially with the DEVS threatening cryptopia

Did I miss some important messages? What have devs threatened cryptopia?

Anyway, cryptopia is now able to withdraw, since they can sync with wallet now, then I really don't get it why signatum has to be delisted?

They can always talk calmly and resolve their differences and fix the problem. Cool heads should intervene for the profitable benefit of both sides.

Why can't I withdraw from cryptopia?
People says wallets are re-enabled but it is in maintenance.

Yes still there is a problem. And i cant see my waiting payments on the blockchain. I dont know who to blame cryptopia or signatum devs  Angry Angry

Well, if Cryptopia is screwing up blockchain transactions even using their consolidated (clean and uncorrupted) wallets, it makes me wonder. Their criticism of the SIGT team would have carried more weight if they hadn't screwed up withdraws. And it seems they did screw up because people have been having problems and they put the wallets back in maintenance.

Both sides should talk calmly and face to face to try to resolve the problem. They should also pull down all these posts that are causing confusion and ill feelings. Resolving the matter is for the benefit of both sides.

Not sure I follow cryptopia's message blaming leveldb. Signatum seems to be using 1.17 (https://github.com/signatumd/source/blob/master/src/leveldb/Makefile), only 1 minor version behind what is stable in most OS (Debian, Gentoo, Fedora, Suse, Ubuntu...). I can't believe it would be that hard to update to 1.18 (used by Dash for exemple). Maybe I'm missing something... can't say I ever used leveldb.

I was able to withdraw just earlier and it is already 0 SIGT but it did not arrive @ YOBIT

Almost 2 hours and my poor 7 SIGT did not arrive to Yobit from cryptopia.

Be cafeful when Withdrawing SIGT from Cryptopia to other exchanges

I think I lost all my 7 coins

withdraw from cryptopia 300 for test.  says completed in history right away, but no sign of it.  I assume this is because the log jam is internal to cryptopia, within the wallet, or address they consolidated to.

my mining payouts have come in exactly as usual, to the same address I am attempting to withdraw to, within seconds of showing as sent from snova.  there is absolutely no evidence, in my experience, of any issues with the network at large.

has anyone successfully completed a withdrawl from cryptopia to either yobit or gui wallet?

I agree. All these idiots piling up trying to blame the devs, or the blockchain. Yet those of us using this blockchain multiple times per day know that our transactions are processed on the blockchain and completed within a few seconds. Longest I've seen is about 10 seconds.

The blockchain isn't the problem. plenty of hashpower. The problem is with the incompetent fools at craptopia.
I just tried to withdraw money from snova about success. But the 0.02 sigt deposit is still not found on the blockchain. do not understand what is going on For local PC, the message is still successful but the blockchain lookup does not have that.

Hi,

The SIGT wallet is now available for withdrawals. Any pending deposits will be processed as soon as we can, you will need to withdraw these again ASAP once they are processed. The markets will remain closed and SIGT is still going to be delisted.

SIGT is based on a 6 year old code base and does not cope with the volume of transactions and addresses generated by it's community. It doesn't have an active developer and a resolution to this problem is unlikely.

Please check our News page for a more in depth statement: https://www.cryptopia.co.nz/News

We apologize for the delay in getting SIGT back up however we were dealing with issues out of our control. Good luck with your future trades!

Please be patient while we finish working on the wallet and try not to log anymore tickets, we love talking with you guys but it does make it more difficult to get your issues resolved when we are flooded with tickets ;-)

Thanks,
Jerry
