What Is the ‘51% Attack’ and How Does It Apply to PoW versus PoS?
A 51% attack occurs when a single entity or group controls more than half of the network's total hashing power (PoW) or total staked assets (PoS). In PoW, this allows them to potentially reverse transactions and double-spend coins.
In PoS, the attacker risks having their massive stake slashed, making the attack economically suicidal.
