He makes a serious profit by mining new chains very early and then selling his coins for BTC while they are in bubble price. Merged mining will undermine his power if new chains start coming with merged mining enabled from block 1 and pool ready. I think that's the reason.

Wow, stop being crybabies and start securing Namecoin.

Yeah, the guy is going to punch you in the face really hard, but he's kind enough to tell you a couple days before. Use that time to prepare yourself, and find a way to defend that chain. How can you defend Namecoin? I don't know, but one thing sure, whining against the attack doesn't help, and the time you use to whine is time that's not used to find a solution.

I didn't really care that much of Namecoin before, and now I find it completely irrelevant if the only way of defense that its users find is to whine.

Um, no, and in fact "this thing" (the "blocks from the future/blocks into the past" technique specifically, not the fact that a person with 51+% of a net can break some stuff) is verily patchable, as Geist illustrates.

I'm (positively) surprised. I don't condone what he's doing, but refusing to speak to him will not make the attack not happen. He would simply do it anyway. We can still do whatever we can to stop him from succeeding. Having a direct line of communication to your enemy is mutually beneficial.

Can someone record a screencast of the attack and post it to youtube? It would be interesting to watch the video afterwards in case there are some lessons that could be learned. There was a guy who recorded the Mt. Gox first incident when the prices fell to below one usd. It was interesting to watch his reaction and comments. That time it was only a fluke that he could get in on tape. This time we could be prepared and have analyzing software running and ready for the 19001 block (when the attack is scheduled).

As a business owner, I care if this sort of thing is possible. I'd rather some jack-off boasting about it in advance, than someone just silently doing it for the lulz.

I agree magnet, this crap makes btc coin look like a joke. This whole forum reeks right now. There is a point to free speech and there is a point to trying to run a business friendly forum. Do we want the childish people here? What is the point of the newbie area, if we let people like bitcoinexpress troll the entire forum with his childish attacks?

I'm surprised users like the one who's threatening and damaging the Bitcoin community like this, gets room to speak on this forum.

Uhh, if someone can do this to the Bitcoin network, then the Bitcoin network is already dead? I mean, the whole proof-of-work thing is designed to make it economically unfeasible to attack - if it turns out there's a way to make it viable, then the idea is doomed no matter what happens. Any person(s) being "against it" or not is completely irrelevant. It's just a bit like crying "no fair" when someone's robbing you at gunpoint.

It would be trivial to patch the client and create a save point, we don't even have to mark it now, we could do it later by looking up the block on blockexplorer or somesuch history. Get a hash, code in an exception.

The /issue/ is getting the entirety or at least 51% legitimate miners to download the new client at the same time frame of a day or two. (otherwise the new patched client will get rejected by the 'corrupted client chain' seeing that as the longest chain still based on their rules)

I think begging and pleading is counterproductive. If begging is our "security", we have NO security. What needs to be done is trying to prevent the attack and/or regaining control afterwards. I'm more interested in regaining control, since we probably won't have the luxury of warning with possible attack on Bitcoin someday.

Bitcoin has blockchain checkpoints with every new client version, I'm assuming Namecoin does too. If it does, I'm wondering how will it be possible to rewrite blocks down to 10000? I thought checkpoints are there to prevent it?

How do we regain control? We obviously need to have valid blockchain backup and bootstrap from it afterwards. We would need to make a new namecoin client version and persuade users to update it. Will there be any problems doing any of that?

now this is just childish.
It resembles kids atitudes when they just want to destroy others projects and accomplish nothing of their own.

I've got 1GH/s i can turn to namecoin while they play their stupid game...

I would be put off by the community, not cryptocurrencies.

Looks like someone posted a windows binary with added checkpoints. You might want to give it a try (though I can't vouch for them):

After downloading the blockchain and receiving your namecoins, backup the blockchain and wallet data until this spectacle is over.


You don't expect the technology to come and knock down the status quo in mere months do you? It took Bitcoin two years to become mainstream and it's still a failed experiment with your metrics.

Guys, the issue is not the attack itself. I think an attack like this can be beneficial, even if it disrupts network's operations. The problem is, they are trying to exploit something that's already been fixed, because that's the only attack they have. The experiment will not prove anything from the security perspective, it will however show the mobility of Namecoin users, which is IMO not a very valuable information.

When children stop dicking around trying to wreck things you can actually do something positive by going to reddit and voting http://www.reddit.com/r/Bitcoin/comments/kcxdk/if_reddit_accepts_bitcoin_for_reddit_gold_i_will/

Getting reddit to accept bitcoin for reddit gold would do more than this effort to "help bitcoin."

I'm buying them at Ruxum.

Seriously, btcEspresso, what you don't like about merged mining?
The solution is already implemented, you just don't want to wait that long. Come on...10 days for everybody changing their code? Some people even said that 19200 was too soon.
The solution...Merged mining since 19000 ?
And you think your attack is good for bitcoin? Bitcoin's operating costs would be reduced with merged mining.
Why destroying the only chain that:

1) Is not promoted as a currency.
2) Has a very useful feature that the community didn't want to be inserted in bitcoin's chain.
3) Will reduce the costs of the network relative to its security.

Merged mining is wonderful, Satoshi proposed it and could be bitcoin's salvation if the "mining after monetary inflation stops will be a tragedy of the commons" theory is true.

And again, what will you find out that you can't in a test chain? That the same can be done even against a bigger chain?

This is going to be bad to bitcoin advocates. "See this chain that has been destroyed? Bitcoin relies on the same technology. But hey, put your money in because it's secure." If you destroy namecoin, I wouldn't expect bitcoin prices to rise. The world would take it as "exchanges, windows computers and now the very chain is hackeable".
You're attacking bitcoin's credibility here too.

Also, where's ArtForz ? Does he hate merged mining too. Is he one of these fools that think that's parasiting bitcoin?

Although I have nmc to loose ~1000 I think this experiment has it's merits.

NMC is not really used for anything namespace related as of now, My take is that it had a bad start and it deserve to be used as a guinea pig.

as for iocoin & al, I bet even my mom has enough Ghash to fuck em up.

The vandals dont care what they wreck. Even if it creates actual victims.

Good luck with that.

He believes your loss is in the name of "science".

If you are successful in resetting the blockchain to ~10,000, then my namecoins will seize to exist. What is your plan to reverse this fact once you're done with your testing? I paid real money for the namecoins that I bought. If you don't reverse the consequences of your test once you're done, you will in fact have taken real money from me because the namecoins I had in my wallet will have seized to exist, and the new ones that will have been created instead, will be in your wallet.

My namecoins are in this block: http://explorer.dot-bit.org/a/NEuKQ4uJPRrE7Bf5TmYAByhHieeFqLzYrd

Will you be transferring the same amount of namecoins to that address once your test is over?

Don't keep them in bitparking. It'll be shutting down all namecoin transactions in a few days or block 19000, whichever comes first. If the attack succeeds all namecoins will be considered lost, the exchange will be closed permanently. If it fails the exchange will reopen for withdrawals. If the network hits 19,200 and there is a reasonable hash rate going then I'll consider reopening trades.
