Ethereum Co-founder’s Proposal for Decentralization on the Network
Ethereum co-founder, Vitalik Buterin, recently shared his plan to enhance decentralization within the Ethereum network by adjusting its penalty system. The proposal, outlined in a detailed blog post and later discussed on Twitter, aims to address concerns related to the network’s proof of stake consensus mechanism.
Background on Ethereum’s Proof of Stake Consensus Mechanism
Validators play a crucial role in securing the Ethereum network by staking ETH and processing transactions in exchange for rewards. However, instances of intentional or accidental negligence can result in penalties that lead to a loss of staked Ethereum. One specific issue highlighted by Buterin involves the presence of large stakers or pools controlling multiple validators within the same infrastructure, posing a risk of correlated failures.
At present, a significant number of validators are associated with prominent staking pools such as Lido and Coinbase, which collectively account for hundreds of thousands of validators. Notably, each validator requires a stake of 32 ETH, equivalent to a substantial financial commitment.
Buterin’s Proposal for Decentralization
Buterin’s proposal aims to incentivize physical decentralization by imposing stricter penalties for simultaneous failures among validators controlled by the same entity. By analyzing data demonstrating a higher likelihood of related failures among validators within the same cluster, Buterin suggests scaling penalties based on the degree of correlation in these failures.
He anticipates that this adjustment will discourage the centralization of validator operations and promote a more distributed and resilient network. By making it economically less viable for large stakers to oversee multiple validators operating on shared infrastructure, the system seeks to enhance the overall decentralization of the Ethereum network.
Are validators in the same cluster (eg same exchange, same user) more likely than unrelated validators to miss attestations at the same time? If so, can we tweak rewards to favor decentralized staking?
Possibly yes.

While Buterin acknowledges that this proposal is not without its complexities and may require further research and refinement, he remains optimistic about its potential to enhance the network’s decentralization efforts. By balancing economic incentives and encouraging a diversity of validator operations, the proposed changes could pave the way for a more robust and resilient Ethereum ecosystem.
