How about we all just chill out and wait a little longer for a response from the dev and stop speculating.

They've already responded.

I know, and they said they were looking into it/working on it. My point to everybody is, lets be patient and wait for the next update.

The Blackcoin dev rat4 who is a talented individual has found an attack which applies to Mintcoin (due to it being pow/pos hybrid that has low difficulty for pow component).

Please read it here: https://bitcointalksearch.org/topic/security-analysis-of-powpos-hybrids-with-low-pow-reward-551861

Note the most recent posts where the attack has been executed guys.

Yes, do add to this:

We have tested the hypothesis we found and managed to succesfully stop PoS from being accepted for over one hour on the MintCoin blockchain.
Basicly this means anyone could turn MintCoin into a PoW-only coin for the foreseeable future and due to the low hashrate on the coin a 51% attack becomes really easy with all the known issues that that brings.


We have immediatly contacted the mintcoin devs, long before rat4 posted it in the topic quoted above. I am still waiting for a confirmation that they are fixing the issue at hand.

I'm investigating the issue. I'm not a dev of mintcoin, but I believe in this community and I try to address issues that I can fix in the code and send a patch to devs as much as I can. (Let it be network connection issues that troubled v1.0, or high CPU usage of v1.4, there were one or two more minor fixes I submitted, but I can't remember now:) )

I saw the devs responded to the issue here, but I don't know when they'll provide a fix (or if they believe there's a problem that need to be fixed -- or if there's really a problem). They usually prefer to do their development behind the scenes, and release their changes in a new version.

I'll investigate the issue anyway for my own curiosity. I would like to provide a patch, but it seems like a security issue in the core, so it's not one person's job to fix it. More eyes are needed to validate any changes to make sure the changes indeed fix the problem and don't introduce new flaws. (In fact not only validation, but also code/idea contributions would be needed).

I believe the devs are trying to understand the issue and fix it. Still, if enough people are interested, we may create a fork on github and try to create a patch there, which can later be merged into the main client codebase when it's ready. I would volunteer for creating a patch for this if there are enough people who will contribute -- by reviewing changes, committing changes, or discussing security issues. But it has to be a community effort, I won't dare to change core components by myself and then submit an unreviewed patch to the devs -- it would be risky.

So what are your thoughts? Anyone is interested in working on this?

PS: I haven't read entire https://bitcointalksearch.org/topic/security-analysis-of-powpos-hybrids-with-low-pow-reward-551861 yet; and I might have missed some posts here if anyone proposed a solution. I'm yet trying to digest the issue introduced in that topic and the blockchain explorer.

Just thought
If there is a bug, must it be the dev that fixes it?
Since its open source, couldnt just any one with the skills fix it?
Rat4 for example, who says there is an easy fix. He claims he only want to help mint, then why cant he just fix it? (if there are something to fix in the first place..)

dude, he's the guy that made all of this shit up

they want the price to go down because they think it will help them pump BC so he won't be fixing anything for you


If you notice I've asked that they go ahead and attack MINT several times so we can clear the issue up once and for all but do you see any response other than more FUD?

Of course not, and what does that tell you?

You guys here make more Blackcoin PR as you think here.

All those bashing makes you look like being jealous, focus should be on MINT not on BC here or not?



The focus should be Mint here, and BC on BC forum. All the information that the BC community needed to share with us at the moment has already been shared. The only people from BC that are still on this thread are here to troll.

Haha. Half of your community are bag holders in denial who won't even admit there is a problem so I am hoping Rat4 doesn't touch it. Especially after the rubbish he has had to put up with today.
mr_random why are you here, doing exactly what you just described: "such blatant FUD attempts." All the information about the situation that needs to be shared here has already been shared, you are doing nothing but trolling as usual.

You have always been a troll on this thread, nobody is going to listen to you no matter what you say. Leave the discussion to reputable and respectable members of the blackcoin community.

The reason blackcoin is dropping is a few of them have a majority of all the coins and they had an agreement not to sell more than a certain amount but the thing is someone is selling alot more than they should be

They are dry, cant pump price anymore

Take a loot at the trades at mintpal, mostly 2, 10 and 20 BC ROUND orders.

They have like an hour trying to dump only 1 btc at 6490. Nobody is buying anymore.

They are stuck...
desperation bagholders, eh?  Cheesy

WTH is wrong with ppl in this thread? I cant believe that if a person finds a possibly big fault in your coin, he demonstrates the flaw, he gives mintcoin devs heads up and after no response posts it out to get the attention it needs you guys attack the person, the coin he has developed and try to make this into a FUD war???

This is not a community I would like to be part of

+1.

It's a shame people in the MINT community aren't smart enough to realise new people who might be interested in joining mintcoin are likely put off from joining when they see such blatant FUD attempts.

I would run a hundred miles in the opposite direction if I was new to MINT and read the last 5 pages in this topic  Cheesy

Unless somebody wants to help Blackcoin out by identifying and publicly announcing their security flaws, lets leave the coin alone. We need to stay focused on Mint so that when the security issues are figured out we bounce right back to normal.

All PoS coins are theoretically vulnerable to 51% attack

The dev team has said if an issue arises they will take care of it

That's good enough for me. until then I haven't noticed any issues. these guys aren't going to get a multipool to last more than an hour or so for this. People have better things to do with their hash than waste time with it.

True at times they are the main buyer of their own coins. They try to pump in hopes to attract buyers but if one of the people in the group is selling from their holdings then they are buying their "friends" coins

A sell atack since block 2014-04-02 18:51:36 on mintpal over BC! jejejeje
