What is a 51% attack on a blockchain?

Blockchains are distributed ledgers that record every transaction made on a cryptocurrency's network. A 51% attack is an attack on a blockchain by a group of miners who control more than 50% of the network's mining hash rate.

How does a blockchain attack work?

People in control of such mining power can block new transactions from taking place or being confirmed. Attackers use 51% attacks to reverse transactions that have already taken place, in a blockchain, in what has come to be known as double spend.

A 51% attack works by overruling an existing network to take over the set security protocols. These impacts may or may not be severe, but it all boils down to the power of attackers hold. So, the more percentage of hash power the attackers have, the easier it is to carry out the attack. Ultimately, the damages are more consequential.
