I heard that block chain is unhackable.


Is it true that the block chain is unhackable?
It is hack-able. hey are not immune to attack. Any technology has weak points and attack vectors, and the blockchain is no exception. The blockchain ledger is distributed across nodes around the world. To hack into a blockchain system, you would need to take control of 51% of the nodes. In most scenarios, this cost more money to do than it would be worth.

Theoretically, a quantum computer may be able to hack blockchain technology. However, I believe that we’ll find a solution to this problem well before it’s even remotely a possibility.


Lastly, sloppy coding and a lack of security auditing could lead to a blockchain hack, but that’s not the blockchain’s fault.
