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.
