Ethereum co-founder Vitalik Buterin introduced a new way to strengthen the decentralization of Ethereum staking by penalizing validators for correlation failures.
Decentralization incentives:
Buterin’s proposal aims to encourage decentralized staking by imposing greater penalties on validators for correlated failures. If validators controlled by the same entity fail together, they will incur a higher penalty than if they failed independently.
Basis for proposal:
According to the theory, mistakes made by a single large actor are more likely to be replicated across all the “identities” they control. Validators within the same cluster, such as staking pools, are more likely to experience correlated errors due to shared infrastructure.
Implementation and Impact:
The proposal proposes to penalize validators proportional to their deviation from the average failure rate. This approach may reduce the advantage of large Ethereum stakers over smaller entities. This is because large objects are more likely to experience spikes in failure rates due to correlated errors.
Potential benefits:
This proposal could encourage decentralization by encouraging separate infrastructure for each validator and making solo staking economically competitive compared to staking pools.
Other considerations:
Buterin also proposed various penalty schemes to minimize the advantage of large validators over small validators and investigate the impact on geographic and client decentralization.
conclusion:
Vitalik Buterin’s proposal aims to strengthen the decentralization of Ethereum staking by penalizing validators for correlation failures, potentially making solo staking more competitive and encouraging decentralization on the Ethereum network.
