I guess this has nothing to do with Artforz' "time travel exploit"?

@phelix If you are referring to the question of what could one do if they could time travel with the blockchain information, then no, this is something different. Timejacking is forcing someone else's computer time to drift away from the normal time in order to make them not accept valid blocks.

@ThePiachu hehe, no I meant this: https://bitcointalk.org/index.php?topic=36425.msg555003#msg555003  it is something different, though.

@phelix Hmm, I don't entirely understand what is described there.

if it was performed successfully we wouldn't know it- I guess we would only know if it was unsuccessful- maybe people are performing it every day- maybe I'm performing it right now!

The question itself is interesting, but merely _linking_ to an external description of the timejacking attack is not helpful IHO

Against Bitcoin specifically or do you want to know of a timejacking attack on any chain (e.g., SolidCoin)?

@StephenGornick Bitcoin mostly, but information on other chains is also fine.

The [timejacking attack](http://culubas.blogspot.com/2011/05/timejacking-bitcoin_802.html) appears to be a pretty straightforward attack to pull off successfully. I was wondering, whether it was ever performed and documented somewhere, or was it just theoretically described?
