Title: Double spending attacks and block depth. Post by: No_2 on May 01, 2013, 03:07:56 PM Am I correct in my understanding that a bitcoin transaction which has been mined into a block and becomes six blocks deep in the chain (has six confirmations) is statically very secure from a double spending attack?
If not can someone point me at info explaining why not. Title: Re: Double spending attacks and block depth. Post by: grue on May 01, 2013, 03:21:45 PM https://en.bitcoin.it/wiki/Double_spending
tl;dr you need to outpace the network to generate enough fake blocks. Title: Re: Double spending attacks and block depth.

Which requires >50% of the total hashing power on the bitcoin network? (Or arguably less according to some recent papers?) Title: Re: Double spending attacks and block depth.
