User705,

Luckily, I got the NXT direct from reputable source, but if this means thousands of transactions will have to be redone, wouldn't it be better to somehow stop things?

I also registered a bunch of aliases. I suppose those would be up for grabs when 24180 is fixed?

I would hope only the tainted blocks would have to be redone. What about all the people with dgex withdrawals pending? What a mess.

Tell me this won't require massive manual cleanup.

James

what is this i hear about thousands of transactions being undone? link to w/e you are talking about pls!

because of things like this...

Made some quick research on the issue with the huge transactions.

The nxts were popping up here first: (passphrase "1")
http://87.230.14.1/nxt/nxt.cgi?action=3000&acc=3705364957971254799

Some of them were transferred to this address:
17910736633224260418

Which belongs to the user nozi123
https://bitcointalk.org/index.php?action=profile;u=168584
(he was online when all this happened)

He also posted in here, asking where his coins are which he bought from dgex.
https://bitcointalk.org/index.php?topic=345619.6640
(his post was later deleted form the thread but I replied him quoting his original question with the account number he provided)

What to do? Can we do anything? Is it worth to do anything?

-4,294,967,296 NXT...

wtf...

looks like the guys who got the Nxt transferred it as well.

OMG

http://87.230.14.1/nxt/nxt.cgi?action=3000&acc=5250567211981518110

1,111,000,000 NXT...

 Shocked

We've got accounts with balances OVER the 1 billion Nxt available...and accounts with negative balances...

I am a bit confused. Will transactions after 24180, eg. everything happening now, be properly reconciled into the new corrected blockchain?

If not, what happens to people who bought NXT since 24180?

James

No automatic reconciliation. Everything after 24179 has never happened.
You should contact to your seller to solve this problem. If you bought it on dgex, they may have stored all transactions in their database so they can reconcile them manually (if they want).

So everyone is doing things and it will all be like it never happened? Due to distributed nature no way to stop nodes from going on as if nothing is wrong. Seems that an emergency stop mechanism might be a good thing. BCNext could probably figure out how to implement a "ctrl-S" on the blockchain...

So, we need to stay up until new client with fix comes out so we can reregister aliases. Contact all sellers and have them resend the NXT. Should dgex.com be warning people?

In the future when there is more and more functionality and data in the blockchain, this sort of thing becomes a bigger and bigger nightmare. Why is everybody so calm about this?

It appears with my account that I mined some blocks that generated extremely large negative amounts, and now my wallet has a negative balance.  Really crazy.

msin,

Don't worry, that didn't actually happen, if it was after block 24179.

There is no emergency stop mechanism in any cryptocurrency. Those of us, who are humans, understand that there is an error in code which leads to wrong transactions and balances. In other way, software is dumb and brainless, it doesn't know that it produces errors. Even more: all instances of NRS have consensus now, that blockchain is valid. Even if you stop 90% of nodes, remains will forge wrong chain.
We just need to wait for fix. And yes - this fix will destroy all wrong blocks since 24180 and their transactions.

It's not so sure, hahah

Even Satoshi may have mistake, not to say some intentional error. On the other hand, I'm not sure whether the ongoing mistake was caused by the core of Nxt or by the client. So the simple fix will have a check of both the sending value and tx fee in the client.

Ddos attacked made 1 second last anywhere from 1 second to many minutes. This would cause all sorts of unexpected race conditions in the software. Just imagining the issues of different nodes trying to reconcile what is what when the heartbeat was different for every node hurts my brain, I am amazed it was able to pick up the pieces and continue to run.

Not sure if the integer overflow was an accident or a malicious hack, but there were a lot of giant fee generating transactions by that account. Probably saw the millions of NXT he was getting and got greedy and went past 2^31. Good thing signed ints were used! Otherwise he could have gotten away with it.

Who could have predicted such an attack on innocent little NXT, still only one month old?

So i dont know if anyone has mentioned this but the person who found and used this exploit has really done us a favor. We should be thanking him. Its really great that this was detected and brought to our attention during alpha and not beta.

Decentralized systems are extremely robust in this respect. All you have to do is query all of your peers once every minute or so, ask them how long their block chain is, if it is longer than yours than ask them to send you a copy. If the chain is legit than you adopt it and ping all of your other peers telling them about your new chain, if it is not legit than you ip block the person who sent it to you for like 24 hours.

I guess its possible this exploit would have been there without the Ddos. Maybe Ddos was a diversion to give him time to cashout the illicit NXT?
