NXT :: descendant of Bitcoin - Updated Information

[yan83]

I've found an issue in peer address sharing mechanism. I forgot to uncomment code that checks peer address before sending it to other peers. This increases time required to find legit nodes coz the attacker floods the network with IPs that look valid but don't host NRS. I'll release a new version in a couple of days, now I'm going to sleep. If something goes wrong, don't panic, I'll fix it next morning.

GOOD WORK

I downloaded latest NXT wallet.

I see there just one NXT  there in web wallet, although there were 301 NXT.

In block explorer it shows that I should have 302 NXT.

What is wrong that I do not see the balance correctly?

And the confirmation amount is more than 1440.

But it does not show that it is forging?

I use latest nxt044.zip client version.

basically, the chain can be rolled back 720 block if i remember correctly, so if we all agree to reload files from that date, we can roll everything back.

BUT if DfB is asleep for that long, we might be fucked, right?

It seems to be bigger problem than some growing fork. Someone find trigger to anti-coins, I suppose.

Developers should put to client some checkpoints for blockhain. There is no checkpoints.

Cos from very start creator wanna network to rise trully decentalized.

Anyway, the result is that the blockchain after the corrupted block is invalid

Exactly, I think. Let's shutdown until we'll get fix. Good night.

Hey guys, I am running 0.4.4 and my blocks aren't updating. If I delete the NXT folder, and redownload it will work, but then the blocks stop updating.

Anyone know whats up?

try to delete transactions.nxt and blocks.nxt, restart the java process, wait 2-3 mins and unlock your account

There are .bak files from about an hour ago, before it all happened.

I have the next files at block 24167 before the hell happened.  I had noticed the block running long and thought I might be on a fork.  Saved them off to re-download the chain.  {I have verified at that block.}

But, we really don't need the blockchain at any level.  Most likely, there will be a new client to fix the issue.   That will result in the chopping-off off of the bad chain.  Essentially, the system starts at block 24168 again.

The important thing for now is that dgex.com stop deposits (and maybe trading) until the new client comes out.  Then, all will be fine with a new client.

agree.
i think the fix will be quite easy, it's just to invalidate these "ghost" transactions

hmmmm what do u mean?

The issue will be resolved once CfB wakes up

[jl777]

It used to have integer overflow amount of fees in every block and also big lag.
Now back to the normal fees and almost no lag.

I guess Ddos is still super active with less than 10% of the people forging, but at least the scary looking fees are gone

Will all transactions after the overflow fees crept in have to be done over? I got big deposit during that time, don't want to lose it!

I think CfB can invalidate only the "fake" transactions occured previously. don't worry and have a good night

[hilotime]

Hello,

I am posting this here as I don't know where else to turn for help.  I purchased 2500.0 NXT from dgex.com and immediately withdrew it, sending it to my account: 14900499787773314124.  this was close to three days ago.  I have attempted to make contact through dgex.com, but have not heard back from anyone.  For details of the transaction history via dgex.com see the copy & paste below:


Time       Order / Event   Value
2013-12-22 11:14:02       Withdrawal fee   0.00000000
2013-12-22 11:14:02       NXT Withdrawal COMPLETED   -2500.00000000
2013-12-22 11:10:45       Buy 2500.00000000 NXT at 0.00003488 each   -0.08720000
2013-12-22 10:57:45       BTC deposit CONFIRMED   0.10000000


Please, any advice or news would be appreciated,

hilotime,

Your acct has the 2500!

http://87.230.14.1/nxt/nxt.cgi?action=100 and input your acct.

I had the same problem, reload client and it fixed it.

CfB doesn't invalidate anything himself.  The client will invalidate it.  Also same stuff happens in XBT so don't stress.  See http://blockchain.info/address/1J1F3U7gHrCjsEsRimDJ3oYBiV24wA8FuV

ok, that's good aswell

[hilotime]

Thank you, James.

When I follow your link I get to the blockchain explorer where I enter my account number after which I can see the transaction for 2500.00 NXT.  However, now when I try to connect to my client (https://127.0.0.1:7875), my browser tells me it cannot connect to this server.  Do I need to set up a new client? If so, how?  I'm a newbie, obviously, and could use some help.  

Thanks again,

hilotime,

I am also newbie, so I will try to help, but no guarantees.

try port 7874

If that still gets you out of sync data. kill the java with control C. Delete the blocks.nxt and transactions.nxt and restart the java. It will take a bit to redownload, but after that the client should show same info as blockchain website

James

P.S. You are running the java with start.jar? If not, there is nothing for webpage to connect to, it runs a local server

[mcjavar]

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

EDIT: sorry, it wasn´t me alone doing it. we did it together with j0b from the chat ( http://webchat.freenode.net/?channels=# )
Please donate him some nxt for his efforts:

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:

(he was online when all this happened)

He also posted in here, asking where his coins are which he bought from dgex.

(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?

[hilotime]

James,

Typed 7874 in place of 7875 in the url bar on my browser and still nothing.  I had previously  downloaded Java version 7u45 (developer kit) per NXT wiki.  I'm not sure what you mean when you say to control C Java and .....  Where do I do this?  I guess  I'm more of a newbie than you.  Thanks for helping me out.
