There's already a proposed fix and plan for a hard-fork now. The fix seemingly has some bugs on GNU/Linux, but the planned strategy is sound and accepted by the community at large (it seems). I think this problem can be considered well on its way to be solved without causing actual losses to anyone except those who tried to "steal" names abusing the bug.

Well, the whole tone of his post sounded fishy, but he does mention at the very end of the OP that he made an example of the issue in practice and explains it. I honestly don't have the brain power today to parse through this but my TL/DR makes me think the issue as described is not a protocol issue but rather a missing check in the implementation. That being the case I can't understand the 'post-mortem' tag (unless, of course, someone wants to buy cheaper).

In the meantime he demonstrated the bug on a chosen domain.
It seems that I misinterpreted some informations.
I hope we can fix it quickly.

Have you guys noticed this: https://bitcointalksearch.org/topic/namecoin-was-stillborn-i-had-to-switch-off-life-support-310954 already?

Yes. I saw it from the beginning.
The user 'libcoin'
https://bitcointalksearch.org/user/libcoin-52207
have done his first post on the Namecoin forum and asserted that Namecoin is dead
'This is the postmortems and obituary over namecoin.'
but Namecoin has been always his favorite alt-coin.
'Namecoin has always been my favorite alt-coin'
Here in bitcointalk.org his first word about Namecoin is only in his post where he is announcing its dead.
Very strange.

They are some technical observations made by him which needs to be checked if it they are true or not. I guess that could take some time.
But he could make a very easy demonstration of his theory by transferring a .bit domain owned by somebody to another address and then back to the original owner.

Is there a way to open old wallet in namecoin Q.3.70b?

Code:

[deafboy@Planetexpress namecoinq-vQ.3.70b]$ ./namecoin-qt

************************
EXCEPTION: 11DbException
Db::open: Invalid argument
namecoin in Runaway exception

Segmentation fault (core dumped)
[deafboy@Planetexpress namecoinq-vQ.3.70b]$

edit: Nevermind, wallet file was corrupted. Working copy restored from backup is working with Q.3.70b

Glad to hear it was not a problem with the new version.

I would tend to think you're stuck on the synchronization part.
What block number does getinfo reports? You should have at least 133271.

Yep, it seems it's on an old block (or still downloading blocks?).

Edit: actually the block count is moving up, just slowly..

The latest one from here should be faster, especially on non ssd systems: https://bitcointalksearch.org/topic/annnmc-namecoin-wallet-qt-with-integrated-name-registration-v375-236375

I run Reddit's ALTcointip bot and have the following issue with namecoin now:

Two days ago I've moved the service to a new Linux host. For every coin daemon (bitcoin, litecoin, etc) I've moved only the wallet.dat, then started the daemon. Every coin daemon shows correct balance, list of accounts, and transactions - except namecoin.

On old host:

Code:

$ namecoind getbalance
272.37500705

$ namecoind listaccounts|grep -v \ 0\\.0000
{
    "user1" : 6.00000000,
    "user2" : 0.20000000,
...
    "MYSELF" : 0.00000000,
...
}

On new host:

Code:

$ namecoind getbalance
0.00000000

dv@nique:~/git/altcointip-chef$ namecoind listaccounts|grep -v \ 0\\.0000
{   
    "user1" : 6.00000000,
    "user2" : 0.20000000,
...
    "MYSELF" : -1114.11720000,
}

I'm already running "namecoind -rescan" but so far it doesn't change anything.

The curious thing is "listtransactions" output is the same, except for "confirmations" field:

On old host:

Code:

    {
        "account" : "userX",
        "address" : "...",
        "category" : "receive",
        "amount" : 0.68229749,
        "confirmations" : 9454,
        "txid" : "...",
        "time" : 1374880993
    },

On new host:

Code:

    {
        "account" : "userX",
        "address" : "...",
        "category" : "receive",
        "amount" : 0.68229749,
        "confirmations" : 0,
        "txid" : "...",
        "time" : 1374880782
    },

Should I wait for "namecoind -rescan" to finish? Is it doing something? Should I delete all files and start from scratch again?

On the new host's debug.log I see a lot of the following lines:

Code:

Thanks in advance.

EDIT: I'm running namecoind 0.3.50 on Ubuntu 12.10 64-bit. Compiling 0.3.51 now to see if that changes anything.

could someone upload the current blockchain please? it's still a pain to synch this shit :<

use namecoind + tmpfs and your synced in ~30 min Tongue

excuse me, but what is tmpfs? and how would it help me download an incredible slow blockchain?

BitName complements Namecoin? Or competes with Namecoin?

At the moment I haven't got the time to read the whole thread, but maybe someone of us Namecoin users already has a deeper understanding of BitNames. This is the main thread on BitNames/Bitshares/Bitmessage:
https://bitcointalksearch.org/topic/bitnames-dns-auction-250612

A very good question.
I think this is still not so clear at the moment because it is only a concept.
Some ideas could be also integrated in the actual Namecoin.
