Ethereum researcher: Anti-correlation penalties can improve decentralization, the community should consider it in future updates

Ethereum researcher Toni Wahrstätter published an analysis on "Correlated Attestation Penalties". It said that this is a quick quantitative analysis of anti-correlation penalties, studying their potential impact on staking operators and CL clients, and mentioned Vitalik Buterin's previous suggestions on anti-correlation incentives. It concluded that implementing anti-correlation penalties is a good way to combat economies of scale without requiring the protocol to distinguish between individual validators. While the analysis looks at staking operators and CL clients, there are more properties to analyze. For example, this includes hardware setup, EL clients, geographic location, ISP providers, etc. In the end, anti-correlation penalties are a good way to improve decentralization, and the Ethereum community should definitely consider it in future updates. In response, Vitalik Buterin affirmed his research on the X platform, noting that Wahrstätter expanded on his analysis of cross-validator correlation last month and adjusted validator incentives to support decentralization.
