Can the Blockchain be hacked?

[BittBurger]

If no, why not?

[wopwop]

no

[empoweoqwj]

Nope.  It can be forked though

Baring an as of yet undiscovered flaw in the protocol the simple answer is no.  The reason why is because the network operates in a trust free manner.  Everything your node receives from other nodes is verified independently first before it is acted upon or relayed.

because its on everyones computer. i guess you missed the first lesson of bitcoin...... its decentralised, hacking one location wouldn't/shouldnt harm the entire network

[oakpacific]

It's not software, so it can't be hacked.

[Icaris]

Nope

[revans]

Yes


It has been hacked before and it will inevitably be hacked again

If you're a very good hacker ( you know, the kind that can get into the FBI in 1 minute while simultaneously receiving a blowjob), you can hack it.  But it takes very big skillz, a multi monitor computer, and a nice graphic interphase that shows you your hacking with cute animations.  But it can be done.

What I believe our friend regains is trying to say is: Bitcoin clients/services have been hacked, this is not an invulnerability of the currency but of the people who look after your coins. So what you want to do is not use online wallets!

[Amph]

it's like hacking internet

The blockchain itself is just data and I wouldn't readily apply the verb "hack" to it.

Certainly the Bitcoin network could be hacked.  Some of the proposed mining attacks would be hacks.  One might consider exploiting a hard fork to be a hack (to my knowledge, we've had 2 accidental hard-forks to date; we could easily have more in the future).

However, it doesn't stop there.  Everything involving a computer that's even remotely clever is considered a "hack" these days.

Would exploiting repeated random numbers to take peoples money be considered a hack?
Would the block-header prayers be considered a hack?

We can say that it must be extraordinarily difficult to meaningfully hack the network.  The likelihood of a devastating hack is becoming more remote with time.

The Bitcoin can´t be hacked, people with wallets can be hacked. It´s the human who is the weak factor in the protection chain. Sorry for my horrible English.

[freequant]

It depends

[indianplayers]

Nope. Almost impossible currently

[crazy_rabbit]

No, but your $300 windows laptop can. :-)

[niothor]

Nope. Almost impossible currently

You're contradicting yourself.
If it is almost , there there is a way , so the answer it's yes.

[Tirapon]

no
