In the keynote speech at the Ethereum Community Conference (EthCC) in Brussels, Vitalik Buterin pushes for Ethereum to respond to hypothetical 51% attacks in a more automated way.
To gain a deeper understanding, a 51% attack occurs when an individual or group controls more than 50% of the computing power of a Blockchain network, this allows them to perform malicious actions. These attacks compromise security and trust in the network.
Specifically, Vitalik Buterin, stated: "This is what I propose we investigate further and build." Arguing, one of the biggest concerns is that this could result in censorship on the network. Particularly, he suggested that a possible solution would be for honest validators to be automatically moved to a minority fork of the chain if transactions or validators are censored.
Now, one of Buterin's most concrete proposals that he was advocating for came from the idea that recovering from chain attacks becomes very difficult if that chain ends. This is why increasing the quorum threshold to 75% or 80% could help avoid this.
