Damn I really want this FUD to keep going on to scoop up the cheap coins. But your uselessness is way too evident. And it's wasting everyone's time to pay you any attention
1. There was no fork due to 51% attack. Fork at 5400 was planned since weeks
2. Time warp attack was solved as it was there in the Litecoin as well. That fix is incorporated in Auroracoin source too
Here's the diff for that
https://github.com/litecoin-project/litecoin/commit/b1be77210970a6ceb3680412cc3d2f0dd4ca8fb9This is as low as I will go to name calling. But you all (the one's claiming attacks) are clearly losers.
The patch that you link to does nothing to solve the exploit in the KGW. It does solve, however, a flaw in the linear difficulty re-targeting algorithms that were of common use prior to these past few months. Bitcoin and Litecoin adjust difficulty in that manner. For an understanding of what that patch fixes, read through the posts of the individual that wrote that patch. ArtForz details the possible attack in the following thread:
https://bitcointalk.org/index.php?topic=43692.msg521772#msg521772I urge you to read through this

https://bitcointalk.org/index.php?topic=504103.msg5573196#msg5573196) thread and pay specific attention to the posts belonging to Nite69. Although BCX never comfirms that Nite69 is on the right track in uncovering the KGW flaw, he is. If after reading through the two linked threads you still do not understand the flaw, I would be more than happy to try and explain it in greater detail.
Edit: Although the original link provides some information, the meat of the discussion is in the new link I provide.
Any coin that implements the KGW is vulnerable to a time warp attack, and the only thing that can stop such an attack would be to have significantly more power than the attacker. Then again, there is no way of knowing how much, if any, power would be needed until such an attack is attempted. Furthermore, miners that do not have multiple pool or solo mining backups are doing the users of the coin a disservice. Pools can be brought down, thus reducing the amount of power an attacker needs to fork a chain.
This exploit is real, and it is only a matter of time before someone takes advantage of everyone's false sense of security. People can hate on BCX or MarkM all they want, but I would urge those people to understand what they are truly trying to say. MarkM consistently harps on the idea of hashing power, and for good reason. If a PoW, blockchain based coin is to be taken seriously and used daily by people around the world, the chain needs to be secure. The chain can only be secured with hashing. If a chain is not secure, a malicious individual will attack it. That is the reality of this world. Honestly, each and every developer and user of a coin that implements the KGW should be thanking BCX for bringing to light the time warp flaw.
