[ANN] [MINT] Mintcoin (POS / 5%) [NO ICO] [Fair distro, community maintained]

[pym002]

Thanks for the panic!

Just bought some very cheap Mint!

like people who do not know how to wait and give time for a currency will have remorse later

[XbladeX]

What is the nature of the attack and what are the risks to people currently holding Mint?

Was a 51 attack over POW part, cant go further since POS kick back in

If you are paranoid use more than 120 confirmations, this will exclude this attack since POS will always kick back in less than an hour

No double spend can be made with this attack.

then
https://en.bitcoin.it/wiki/Double-spending
and finaly:

>50% attack

If the attacker controls more than half of the network hashrate, the previous attack has a probability of 100% to succeed. Since the attacker can generate blocks faster than the rest of the network, he can simply persevere with his private fork until it becomes longer than the branch built by the honest network, from whatever disadvantage.

No amount of confirmations can prevent this attack; however, waiting for confirmations does increase the aggregate resource cost of performing the attack, which could make it unprofitable or delay it long enough for the circumstances to change or slower-acting synchronization methods to kick in.

Mint attack 51% of POW part was successful no POS block was generated during test attack.
Just becouse test attack wasn't created to enebled double spend that doesn't meant it is impossible.
Do you realy want attack to create panic ?

"Successfully tested on Mintcoin: no PoS blocks from 203231 up to 203441, more than 1 hour of real time."
just check blocks in explorer to see it was for real...
Mint just need fast fix that is all

Stop with the FUD it's already been shown that the attack was foiled by the proper functioning of the coin and no doublespend is achievable by that vector

Actually, the only reason PoS kicked back in is because we stopped the attack. One could easily stop the PoS chain for 24 hours+ if he'd wanted to. Hell, even a year is possible.

Also, this is a 2 part attack:

1) Make the coin PoW only
2) 51% attack.

The second part we did not perform, but we could've done a double spend then.

Anyhow, good that the dev finally reacted, hope to see a fix soon!

they said they would release a fix if one becomes necessary because theoretical possibilities are not much to worry about

The dev should try to reproduce this and see if it is a problem. For all we know rat4 and his team could have tried this over and over and when they finally manage to get 100 blocks in a row they posted that result as if it is an easy task...

You would rather it's not theoretical and he actually 51% attacks your mint blockchain??  

You should be careful what you wish for. He reduced the network to relying on almost zero difficulty proof of work mining, a 51% attack at that point is trivial.

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=50
http://mintcoin-explorer.info/chain/MintCoin?hi=203433&count=50


Secondly, even within this period, there are still some PoS blocks that occur:
https://i.imgur.com/LydCerH.png

Most 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?

[mgburks77]

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. exactly

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.

So it's even worse than we thought. The entire network was frozen with no confirmations, and that was only carried out by the first stage of the attack.

Game over.

Any news on MINT being added to https://www.vaultofsatoshi.com/?

That should put some wind in the sails.

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.

Really.. REALLY?

You highlighted two blocks.

http://mint.blockx.info/get/block/000006947fae36e3330c38ecfe55097c1da496f0c8f3e4a4f08543aed1227253

Those two blocks. They are Proof of Work blocks. And both look like they processed transactions FROM <address> TO <another address>.

You're not technical at all, right?

Nice investigation.

Thanks for catching my mistake, just trying to figure this out

[maarx]

I hope this gets fixed, is all. I have a lot of mint.

[moderndezigns]

ok guys here are all the blackcoin liars

[mgburks77]

you guys are really shooting yourselves in the foot with this crap, look at how far blackcoins price has dropped since you started doing this

I suggest you get the attack underway before it hits zero

[moderndezigns]

remember to like our facebook page

[maarx]

We are here trying to help. Is all. There is a SERIOUS error in the Mint code. What do u want? We are talking about an 1.5m market cap here, which can go void in an instant.

We're not joking here or promoting "our blackcoin".

[sargecap]

Im still holding my last 10% of mint but I admit I have panic dumped some

any progress from the mint dev team yet?
