What Is a ‘51% Attack’ and How Do Fees Mitigate It?
A 51% attack occurs when a single entity or group controls more than half of a Proof-of-Work network's total hashing power. This control allows them to censor transactions or reverse confirmed transactions.
Fees mitigate this by increasing the total revenue for honest miners, making the cost of acquiring and maintaining 51% of the hash power economically infeasible.
