Definition
A type of attack where a group gains control of the majority of nodes. This would allow them to defraud the blockchain by reversing transactions and double spending ether and other tokens.
In Ethereum proof-of-stake this would be achieved by accumulating more than half of the total staked ether. This would allow an attacker to decide which new blocks are added to the blockchain. However, to revert the chain or double-spend an attacker would require at least 66% of the total staked ether.
