🔍 What is a 51% Attack?

A 51% attack refers to a situation in blockchain networks, particularly those using proof-of-work (PoW) consensus mechanisms, where a single entity or group of entities gains control of more than 50% of the network's mining power. This control allows them to manipulate the blockchain in various ways, undermining its integrity and security.

⚙️ How It Works

Mining Power Control: In a PoW system, miners compete to solve complex mathematical problems to validate transactions and create new blocks. If an attacker controls over 50% of the total mining power, they can outpace other miners.

Double Spending: The attacker can reverse transactions they made while in control, allowing them to spend the same cryptocurrency multiple times. This is known as double spending.

Block Manipulation: The attacker can prevent other miners from confirming transactions, effectively censoring transactions or blocking specific users from making transactions.

Forking the Blockchain: The attacker can create an alternative version of the blockchain, which can lead to confusion and loss of trust in the network.
