allcrypt, I understand the stress you're in right now with the responsibilities for people's money.

We're trying to help you out.

My personal method is to rule out all the possibilities to find the problem. I can only look in to the SocialCoin code, not yours so I have to ask you all these questions in order to move forward.
I am not suggesting there's anything wrong with your code, I am simply trying to find and fix the problem as fast as possible.

Caching seemed like a possible culprit if expiry is left to 0.

If things work normally, then don't and then work normal again, it's safe to assume there was some form of attack. Maybe against the wallet, maybe sql injection to hijack other users accounts/wallets.

I would like to see this problem getting fixed. Crypto doesn't need another exchange getting in trouble and if it's caused by the wallet, the problem may be spread across every bitcoin/litecoin derivative.

If you want we can get in touch on irc and work on the problem more directly. PM me if you want.

Are you sure it happened to legit users?
Since generating new addresses gives no conflicts and it stopped happening, your site may have been under attack.
Maybe someone tried to overtake someone else's wallet or some other attack.
Poloniex was recently hacked by sending the same order multiple times at the same moment.

Did you find anything out of the ordinary in the coind or webserver log files?
You should be able to track the http request and match it to the rpc call. If the call isn't showing in the coin's debug.log you have caching enabled or there was an attack.

allcrypt, I'm not the original developer but I did the last update and looked through the code (changes from original). So let me try to assist you until SocialCoin replies.

The wallet isn't doing anything different when it comes to generating addresses except from starting with a capital 'S'.

Can you try to generate a new address with a rpc call from the command line and see if that address is already in your database?
This way we can determine if the error is in the wallet or your code.
Which command you use to generate a new address?

I don't know the code of your site, but are you using any caching mechanisms like xcache, apc, memcache?
It sounds like your application is caching the addresses somewhere and reuses them.

I will go through the code again now and see if something weird is happening but I advise you to look in to your code as well because the error is probably caused in there.

This is a good example of how the crypto community can gather funds and make things happen:

Don't forget organizations that don't accept crypto currencies yet. We can help them install wallets and inform them about crypto.

We're about to start compiling a list of organizations we can approach to accept SOC.

Team SocialCoin can count on us!

The community seems to be growing, just like the SOC ecosystem.
Great work DFiLeR!

Another paper wallet: https://github.com/Hotpoolz/socialcoin-paper-wallet
It needs graphic updates etc. but for now you can download it and generate/print your paper wallets.

Feel free to host it yourself or fork/modify!

Nice! 25k sent from Hotpoolz:)

Bonus sent from Hotpoolz!
I'll come over to reddit soon...

Looking good!

Good idea to post the pools too;)

If you post your SOC address you'll be rewarded for your work:)

We have a working paper wallet!!!

A fellow user looked into SocialCoin and the paper wallet code and gave us the information required for porting the wallet generator.

I tested and confirmed it generates valid public and private keys.
Here is a test transaction: 600829527873e1b27932bdef0b9bd4c2d3890846e0b47fbfde7159564f785c5e-000
Private key imported fine.

As promised I him sent a bounty + bonus because this could really help SOC. His address: SYX47QvyG2YncSFEHiDQXNZy64YZmxQNik
I hope you will reward him too:)

From here it's a matter of changing some names and making a nice SocialCoin paper wallet image.
I can't make any promises when it's done.
If you would like to help creating graphics let me know.

The problem has been solved and bounty is on it's way.

Thank you all!

Great idea!
Hotpoolz will add to the bounty!

SocialCoin is offering a bounty for converting the liteaddress.org paper wallet generator to SocialCoin.
The bounty stands at 60k SOC.

The only thing required is to have the code generate a valid SOC address, which starts with "S" (63).
I can manage all other naming conversions and images. Just need help modifying the code to generate a correct address.

Who can help us out?

Diff has been 1.9 indeed, but 0.7 also in the last few days. If you mine the coin a while you'll see difficulty drop and rise.

Recently the coin spiked at 200 satoshi at Poloniex. And I'm not talking about an "optical" spike like you see on cryptsy but a real spike where all orders up to 200 were filled.
Difficulty went to 9 I believe and since then there's been more interest in the coin. Diff has been a bit higher overall since.

I haven't been calculating lately because every time I did, SOC was the most profitable compared to all other coins.
I was actually happy SOC wasn't listed on the comparison sites 'cause that meant more coins for me;)

It looks like the coin is about to take off now so I don't know what the future brings. All I can say is that SocialCoin is very profitable and has been THE most profitable at times in the past.

This may be your last chance mining the coin with such low difficulty and 10k blocks. Only a few blocks left before it's halved to 5k.

Yep, it's been very profitable for a long time!

At this time there's still more than 300.000,- SOC (in 1000 SOC bonusses) to be earned by block finders at:
soc.hotpoolz.com

Great to see SocialCoin apps coming out!

10k bonus from Hotpoolz sent!

Thanks!

That spike was a nice bonus for SocialCoin supporters:)
I expect there to be more of these at poloniex.

@DFiLeR
You are right the coin is a great investment! At 0.00000008 it's a real bargain now. Doubling/tripling your money should be relatively fast. Or you wait for the next spike to come...

@SocialCoin
I would like to propose to put out a bounty for someone who forks the paper wallet for SocialCoin.
This would add another option to donate funds and a way to securely store SOC offline.

Supporters of this idea could donate for a bigger reward for the developer.
Hotpoolz will start by donating 50.000,- SOC

1.000.000,- (One Million) SOC reward for miners!!!

To celebrate our return and make up for past downtime Hotpoolz is now giving away One Million SOC in the form of 1000 x 1000 SOC rewards for blockfinders.

We will start counting when the pool's valid block count is 8247 and will end when the pool found a total of 9247 valid blocks.

Here is a list of the new pool's improvements:

• SSL Protection (enabled by default)
• Mining on alternative port 80 for miners behind firewalls
• Colocated hardware with redundant power supply

Come accept our Million apologies at soc.hotpoolz.com

Hotpoolz is back up!
I bought some hardware and took it to a data center. It took some time to set up properly.

Our previous server (vps) just disappeared one day, to never return.
It is likely the connection and reboot issues in the past were caused by the hosting company.

Luckily I made backups every 15 minutes so we lost just a few minutes of mining, which is compensated for with 0% fee for a while.

Outstanding payments have been made and you can withdraw your coins any time in case you've got some waiting in your account.

I want to thank you all for trusting me to not run off with your coins during the downtime!
Hope to see you back at Hotpoolz, the first SocialCoin Mining Pool

At coins-e, the price goes over my asking price again and again, but I haven't sold anything so far.
Even worse than cryptsy... Like my orders aren't even there.
