Ethereum developers are considering a protocol update that aims to enhance network security by increasing the finality threshold from 67% to 80%. This change is intended to improve resilience by ensuring that the network remains operational even during potential disruptions. Additionally, the proposal suggests reducing the slashing threshold from 33% to 20%, which would lower the financial penalties for validators in the event of a 51% attack, currently estimated at $30 billion. The update also explores adjustments to the fork choice rule, potentially reducing the threshold needed to dominate the fork choice from 50% to 40%. However, by adopting non-standard threshold choices, such as 50% to notarize and 83% to finalize, the protocol could maintain a 50% threshold for fork choice domination, while reducing the slashing percentage in a finality reversion to 17%. These changes are designed to ensure that the network can recover finality within hours to days, even if a significant portion of validators go offline.
