51% attacks are among the most significant ways blockchains, protocols and web3 infrastructure can be attacked.
They involve an attacker gaining control of over half of a network's mining or staking power, thereby getting the power to do damage like censoring transactions, double spending money, or even changing blockchain history altogether.
As a solution to this problem, Buterin suggests the adoption of "automated countermeasures," which will allow the nodes in the Ethereum network to automatically flag and handle censorship attempts.
Buterin acknowledges that doing this will be highly difficult, especially getting everyone on board.
However, a soft fork of the Ethereum network might help the community agree more quickly on the proposed changes, including light client adoption, zkEVM verification support, and Quantum resistance solutions.
