The users who organized the 51% attack aim to block the transactions of other miners on the blockchain and take control of the system. Double spending can occur if attackers reject other transactions on the blockchain.


What is the Probability of a 51% Attack?


Large networks are less likely to encounter a 51% attack than small networks. A 51% attack on blockchain networks like Bitcoin is almost impossible. The Bitcoin network has a technological infrastructure that can quickly protect itself against a 51% attack. On the other hand, in blockchain networks with low transaction volume, there is a 51% attack probability, although it is low.
