I know it is decentralized and the hacker needed to have control over 51% of the network to 'hack' it! BUT, like any other hack, maybe there is a way we don't know about YET! Everything is 'hackable' from the moment it is online!
What do you think about this?
The whole idea is: essentially there is nothing to hack. Everything is public, transparent, open, and shared. Everybody knows everything. There is no feature or part in the software whatsoever that is supposedly 'hard to hack', that some day some smart ass hacker might break into.
let's be a little bit crazy here: imagine a virus that propagates through mining software and eventually reach 51% of the network silently! By that time, the 'hacker' in control, would change/manipulate the transactions...
Even if something seems safe today, that doesn't mean it will be always safe!
