Re: I don't believe Quantum Computing will ever threaten Bitcoin
Bitcoin can answer to a crack, that was done before with a rollerback, but some attack would be bad for the business could be a complete CAOS for a while.
With the amount of transactions bitcoin currently has >300k/day, a rollback is almost impossible. Planning a rollback and getting everyone to agree with it would take some time, and what would you do with the >300-2000k transactions that were confirmed before the rollback?
There is a lot of money moving in bitcoin. How can anyone justify cancelling than many transactions?
Imagine. You sell your car for bitcoins, wait for it to confirm hand over your car and then the next day you don't have your coins anymore
What would that do to the reputation of bitcoin?
Maybe, if there would be a HUGE theft that would be noticed immediately, but that would have to be REALLY huge. I cant imagine such a thing happening anymore.
When a rollback was done bitcoin was a lot of smaller and there weren't as many transactions then. And the bug would have destroyed bitcoin if it had not been fixed. (someone created ridiculous amounts of new bitcoins from nothing. IF I remember correctly he created hundreds of millions of bitcoins...
so something had to be done)I was speaking in the case of a big attack, if it happens a little one its the same as you be hacked in your browser with a keylogger, that happens everyday or some guys stoling exchangers.
I think should exist some link in bitcoin.org website to complaint about transactions maybe hacked and should be marked as under investigation if we discover a padroon maybe can help to catch the bad guys.
