Please save this here or timestamp/sign it. GPG or Namecoin.
It is needed if I decide to make public announcement later as a proof I did not made it up after the shit hit the fan. Until then it will remain Mystery to be mined.

The network tries to produce one block per 10 minutes. It does this by automatically adjusting how difficult it is to produce blocks.

Thanks everyone! I'm not sure I will come out with the data corresponding to this hash before someone else figures out this and announces it publicly. Learning from history the good guys get no profit and only troubles from being white knight on donkey instead of black knight on stallion. I'm not sure how seriously it might affect Bitcoin but it is about exploitable vulnerability on Bitcoin accepting service that might go down completely as a result of this.

Will not tell anyone until I finish one of first 4 options. If one is following Bitcointalk closely he easily might figure out that by himself. Update: I'm dissapointed. I will goatse them at midnight. I don't want to do this because I and other people need them but what is going to be inevitable must happen sooner or later. Better it's me who pull the trigger and not someone else gets all the little fun.

Notified the owners and got response. I will explain everything tomorrow and post both the file behind the hash and full dump. Im very drunk right now.

Regarding the timestamping of your SHA256: Why don't you let the bitcoin network prove your timestamp? (e.g. via Bitcoinproof)

But does Namecoins serve the same purpose better? And Bitcoin network cannot be very accurate for this because it can vary block times for +/- 2 hours right? But it sill is very reasonable way to do, will take deeper look when have better state of mind. The flaw turned out to be not so dramatic. I will post everything at once as soon as I get in mood of writing long text.

Bitcoin seems to be more active, and seems to attract more computing power, AFAICS. And Bitcoin network cannot be very accurate for this because it can vary block times for +/- 2 hours right?
On average, every 10 minutes a new block is generated. So yes, that timestamp could be 10 minutes after you sent the transaction, or even some more minutes later. In addition, the block is only "really" assured after 6 transactions, so add 1 hour just to be safe. However, I doubt that this will cause any problem, because it's usually not about minutes but days. I bet that quite some time elapsed between your discovery and the creation of the dataset whose SHA-256 hash you published. So I guess that adding 1 more hour (maybe 2) won't make any difference.

The data behind the hash is here: https://bitcointalk.org/index.php?topic=172527.0First I tried to exploit alone for profit (failed), then notified owners, then did full disclosure for everyone to know and be aware.
