Can blockchain technology be hacked ? how?
-
I think: NO! because if you want to hack it, you HAVE TO hack all of computer in his system. It means that you need build a more powerful computing system than a global computer system.
Maybe in future quantum technology can help you create a computer with size = stadium!
-
While it's hard to hack the technology, hacking people is easy and that's how most hacking happens. For example, some trick you into giving out your private key, password, and etc.
-
When someone holds over 50% of the mining utilities there are vulnerabilities in the system and a possibility for double spending.
-
It will take a monumental effort and superior technology to hack blockchain. To do this, hackers would have to "convince" more than 50 % on that blockchain that a transaction happened or didn't happen.
-
The advantage of the Blockchain technology is that it will never be hacked as long as the transaction is already recorded in the Blockchain it is impossible for it to be manipulated or be modified to change the verified transaction that has already confirmed that is showing on a specified Block Explorer system.
-
I think the most likely scenario is the quantum computer attack. With multiple times the total power of a distributed system, a state-owned quantum computer would cause every blockchain to collapse if those blockchain was not programmed for quantum resistance.

Can blockchain technology be hacked ? how?
Basically yes alot of ways that hackers or attacker's might do about hacking they can use alot of tools in order to steal data from others account they can do what they want so our security depends on the feature of our account platform so its absolutely yes for me.

They do not have access to the keys. All manipulations are made in the browser using javascript.
But this does not mean that they will not be hacked and will not replace javascript. In any case, if hackers succeed, they will not get access to 8 million wallets.
