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..)
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. So far a new person reading this topic will see that 50% of the regular posters are actually liars if they read the last few pages and then check the blockchain explorer to see the attack in black and white. I used to be a big MINT supporter, feel free to check my post history I was here in the early days. I would recommend people look through your post history on here as well. You went sour on Mint a long time ago, and have since been back only to hurt the community. Please, stop posting here and aggravating the problem. "50% of the regular posters are actually liars" is complete BS and you know it. You are refering to 2 or 3 different people's comments at most and a few individuals do not represent the majority of the community. Also do not mix up being confused with lying. |

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://bitcointalk.org/index.php?topic=551861.0Note 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://bitcointalk.org/index.php?topic=551861.0 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. +1. Thank you paspi. |

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. |

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. |

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?  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 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. |

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 this blows over we bounce right back to normal.

I've just noticed something while going over the block chain. First of all, the attack was really just from 203231 to 203405 before it started to be interrupted by even more PoS blocks: http://mintcoin-explorer.info/chain/MintCoin?hi=203233&count=50http://mintcoin-explorer.info/chain/MintCoin?hi=203433&count=50Secondly, even within this period, there are still some PoS blocks that occur: https://i.imgur.com/LydCerH.pngMost importantly of all. Through the ENTIRE attack period, not a single transaction was confirmed by one of the PoW blocks (aside from the PoW blocks producing their 1 MINT). The only transaction confirmations were done by the few PoS blocks which interrupted. How is this possible? There are way, way more PoW blocks, but none of them confirmed transactions over an entire hour? Is that because PoW blocks cannot confirm transaction during this "attack"? If so, then this "attack" cannot be used to double spend or do any real damage. Right? Yes. exactly Really.. REALLY? You highlighted two blocks. DO NOT POST SESC LINKS http://mint.blockx.info/get/block/000001cf24011a61e757be862418390dc7a6c1d20d3cf3798ffb5ae15f9c9ba5Those two blocks. They are Proof of Work blocks. And both look like they processed transactions FROM <address> TO <another address>. You're not techincal at all, right? Nice investigation. Thanks for catching my mistake, just trying to figure this out |

The entire network was frozen with no confirmations, and that was only carried out by the first stage of the attack. Game over. Nice try, but no that is not what that means. As you can see, PoS blocks interrupted the attack to perform transactions. You should stop saying things about this mr_random, even if what you said holds any truth everybody knows you have and always will be a troll on this thread. Leave the discussion to the reputable and respectable blackcoin representatives. |

So stormia, are you saying that this statement: Mint attack 51% of POW part was successful no POS block was generated during test attack. is demonstrably untrue? Yes, but I urge people to have a look themselves. Even more importantly it doesn't seem to matter that they were in control of PoW because PoW was not allowed to do any transaction confirmations. The PoS blocks had to interrupt in order to confirm a transaction. |

I recommend you go with black coin
Why is blackcoin's price falling, too? I see big dumps. I would have thought bad news for Mint == good news for BC. |

We have been made aware of potential security issues for MintCoin recently. As we always do, we're actively looking into these issues if any. If there is anything to fix, we'll do it, and we'll do it the best way possible.
thanks, i feel a lot better now. I will buy 40 million MINT. that was sarcasm. can you at lease say if you think this is a major issue or not. He said they are actively looking into the issue. Lets be a little patient. Lets also be thankful that, if there was potential for it, the BC devs chose not to exploit this security hole and do any real damage. |

This is a joke. Nice try to spread FUD about other coins, rat4, to try and promote your pure PoS blackcoin. How is it that Blackcoin prevents attack forks as a pure PoS coin, again?
You say "a sequential chain of PoW blocks can be mined in a flash."
Which is not true. Sure, you could mine all of the PoW blocks that occur sequentially, but there will be many, many more PoS blocks that interrupt those far and few apart PoW blocks.
....
I think you should apologize now rat4, thank him and pay him BIG bounty for helping Mintcoin and others for founding bugs... And even bigger bounty for solving issue... PS:He just mined 1h in POW Mintcoin you want more evidence... ? Do you want double spend ? I already said I regretted how I originally addressed rat4, it was rude, why not include that? Not to mention this is an entirely different problem, so everything I said up until now was concerning "attack 1". Thank you for finding the bug, rat4. But, as far as I can see he has not provided a fix for the issue. He has publicly displayed a security flaw thereby allowing anybody to now take advantage of it, and allowing the entire BC community to use this to defame Mint thread and others. So I still doubt his motives were in the right place, I won't be thanking him for that. |

Cool when will my first coins be sent out?
Another way you can get MINTs without buying them is through using the the MintCoin multipool at hashcow: http://hashco.wsJust sign up and make sure to go to account settings and change the payout to Mint. Hashcow is doing this promotion right now: We are approaching 1 week since payouts in MINT were implemented on http://hashco.ws While I appreciate the new miners who have given us a shot and 'mined' some mint, the uptake isn't quite what I'd hoped for. In an effort to try and get things going, I received a total of 1,850,000 mint in bounties for implementation. If we can reach 300Mh/s in new hashrate that gets paid out in mint, and maintain it for at least 5 days, I'll give away all of it to random miners in the form of 3 prizes; 1mil, 600k, 250k. (personal hashrate will play no bearing on the prize winners, 10Mh/s or 300Kh/s, you'll have the same chance of winning). I'll post updates here on hashrate status if warranted. Happy Mining. Check out this post to see how this multipool works and how it benefits the coin and the community: http://www.reddit.com/r/MintCoin/comments/21yd31/why_i_moved_my_farm_40mh_to_hashcows_and_why_you/ |

I keep getting this unlock button in my wallet what does that mean?
If you encrypt your wallet, that button allows you to unlock/lock it without having to use the wallet debug window. |

I think Jeff Jefferson said he would pledge 300k as well!
yes, but it REALLY has to mint. otherwise it's just another android wallet of a coin. we need to make the difference guys. I also think its not that necessary to use an escrow. I think MINT users are sincere and honest people, am I right?  I also had the concerns about the upcoming android wallet being open source so the others just can copy it. So I would propose a simple not open source app at first in the google play store. Than after a month or two the source code should be released. This is privately offered bounty for a working prototype, upon public delivery. Offered separately from other bounties that may exist. So far the total is: mgburks77: 250,000 stormia: 125,000 garicson: 200,000 jeff jefferson: 100,000 moderndezigns:200,000 Total: 875,000 Bonus for wallet that mints: mgburks77: 250,000 jeff jefferson: 200,000 moderndezigns:50,000 Total: 500,000 Total Total: 1 375 000  I'm sure there are other people willing to contribute! Looks like gonzoucab said he would donate for a wallet that is fully functional and mints as well. (Sorry if I am misunderstanding your post. I don't want you to get left off the list if you are, though!): I can pledge 125K for when a fully functional wallet that mints is deployed. Im also asking a developer for a twitter bot, maybe i will fund myself alone. is not too much.  We are better, we are greener we are mint. Well stormia, i will improve my pledge, i will give the same ammount as you in the same conditions, whatever you decide i will apport the same! Well, in that case, I will add another 75K of donations to the bonus for a wallet that mints! Thanks for showing your support gonzoucab and compelling me to increase mine |

hello http://coinok.pw/faucet/mint/ reactivated - the only problem is that it might need github upgrade - in that case this can only be done in the weekend due to lack of time. what is the github update? glad that i could help reactivate the faucet. the guys were really fast. just sent another 200 mint to the faucet. it would be awesome if others could donate too!!! please stop donating until we see it works with the old github code. thanks Roger that, I will wait for your word. Thank you! |
