51% Attack

What does 51% Attack mean in crypto terms?
A 51% Attack refers to a security risk in a decentralized blockchain network, where an individual miner or mining pool gains control of more than 50% of the network's hash rate, allowing them to unilaterally manipulate the blockchain. This control can enable the attacker to halt new transactions from being confirmed, stop payments, and potentially reverse transactions made during the control period, leading to double-spending. Such an attack undermines the integrity and trust in a blockchain network and can cause significant damage, including financial loss and a decrease in user confidence.
