Understanding 51% Attacks: The Security Vulnerability in Blockchain Technology

 A 51% attack refers to a potential vulnerability within blockchain networks, particularly in Proof-of-Work (PoW) systems. It occurs when an individual or group gains control of more than 50% of the network’s computing power (hashrate), granting them the ability to disrupt the network’s functioning. Such an attack can allow the attacker to manipulate the blockchain ledger by reversing confirmed transactions and potentially double-spending coins.
