there is no penalization algorithm like slasher in this coin.
even if they try to do it. they wont get penalized and can try over and over ( so no risk ).
but enough of this. please read into nature of pos.
i have to go.

That would cost the attacker about $750,000.
Is it really worth it to attack? I mean they are spending 750K to destroy their own money, who would do that?
double spend? there will be other flaws... but currently double spend is most likely to occur with a stake of 51% or more.
If they control 51% of the wealth and try to double spend all of it or a significant portion of it they would be spending nearly 100% of the market cap- there is no way anywhere near 100% of the market cap is going to be spent in two transactions. Meaning if they want to double spend they will have to double spend significantly less than their 51% of the wealth, meaning they jeopardize the remaining part of their wealth. no? Unless they can effectively double spend more than 25.5% (thereby "spending" more than 51% of the wealth they actually control) they would be better off just spending their 51% of the wealth since whatever value is left over after the double spend will be destroyed.

pure pos is untested. we will see what future will bring.
i am into mint now as well.
ps. it would cost bitcoins. that is why "there is nothing at stake". an early adopter of bitcoin can do this. also the marketcap.. is at highest buy/lowest sell.
marketcap only takes highest buy price and multiplies that by coins available. it wouldnt take 750k usd. not even close.
so coinmarketcap is not even close to real value. simple math.
it wont be the expected 20%
you are looking at a maximum of 22%
but it wont be that because not all coins are minting with perfect 20 day cycles, some are not staking and some are being spent resetting the age
btw, i only answered out of my own will, im not scrutinizing mintcoin, i happen to be here with the source code open

"this flaw was addressed by the author of PoS, Sunny King, earlier this year:
Official release build is now available http://www.ppcoin.org/ (via sourceforge)
What's in 0.3.0 release:
Stake generation protocol upgrade (protocol switch March 20th)
Qt UI support
Fix compatibility with vanitygen (note: private keys dumped in v0.2 is no longer importable into v0.3.0, must dump again from v0.3.0 client)
Miscellaneous bug fixes and improvements
The protocol upgrade in 0.3.0 includes a new algorithm to derive proof-of-stake hash modifier, the entity that scrambles computation for stake owners, which replaces the current proof-of-stake difficulty used as modifier in 0.2 protocol. The design was started late September last year, when I first began to realize the issues with using difficulty as modifier. Honorary mention also goes to Jutarul, who independently discovered and verified an issue with using difficulty as modifier and published on bitcointalk in December last year, while successfully executed a demo attack on the block chain. Other changes in the protocol include starting hash weight from 0 at the 30-day mininum age, and requirement that coinstake timestamp must equal block timestamp. Overall 0.3 protocol should significantly strengthen the proof-of-stake protection and resolve the current known vulnerabilities.
My sincere appreciation to co-contributors of 0.3.0 release:
Robert VanHazinga of Hartland PC (dreamwatcher) for the vanitygen compatibility fix
Jutarul for demonstrating stake generation vulnerability
EskimoBob for reporting issue fixed in 0.3.0"

This is the state of the nation in mintcoin. our network is fast and secure. more secure than an pure POS system or a pure POW system
Mint Breed the best of crypto world, im telling you its the facebook of the social economic network.

Also the attack described would not work. Coins are not staked only on coinage, it is only one factor. So even if you made a lot of transactions so all your coins were separated by a small interval, there is no guarantee they will stake at each interval - in fact splitting them into small amounts to make these intervals will make them less likely to stake. You would have to have a very large amount of coins at each interval to even have a chance of producing 2 consecutive blocks. This attack is completely unrealistic.

if i were right, PoW would be useless in the event of an attack, because the high rate of PoS blocks would cause difficulty to jump into unminable levels
As you can see here, the PoW blocks have a different and independent difficulty algorithm than PoS blocks. If you start getting a lot of PoS blocks in a row, the chance of PoW block generation increases in order to achieve the PoW target; so after each PoS block is generated the likely-hood of generating a PoW block as the next block goes up, and after every PoW block, the chance of generating a PoS block goes up. They are both integrated with block targets and difficulties that are independent of one another; so one cannot perpetually overpower the other. This is why PoS/PoW hybrid is more secure vs just PoS only. And, it is also worth noting that over time, the Mintcoin networks actually will get more secure with age, whereas a PoW only coin has the potential to get less secure due to centralized mining processes. Mintcoin is protected from PoW overpowering, as well as PoS overpowering. You cannot know for certain the future of the Mintcion blockchain (at least very far). With Pure PoS, you know the future will always be a PoS block next, and with PoW you know that the future will always be PoW blocks next, but you cannot know the future with hybrid PoW/PoS like Mintcoin.
looking at the code, there doesn't seem to be any difference for PoS when it comes to target calculation and difficulty calculation
they are not independent
look at the times in the image you posted, you will see why the difficulty is at 22 on that block and the others are much lower
The time before the last PoS block and the PoW block is 5 seconds..
