According to Odaily Planet Daily, Ethereum researcher Toni Wahrstätter published an analysis of 'correlated certification penalties'. He said that this is a quick quantitative analysis of anti-correlated penalties, studying their potential impact on staking operators and CL clients, and mentioned Vitalik Buterin's previous suggestions on anti-correlated incentives. Wahrstätter concluded that implementing anti-correlated penalties is a good way to combat economies of scale without requiring the protocol to distinguish between individual validators. Although the analysis looks at staking operators and CL clients, there are more properties to analyze, such as hardware settings, EL clients, geographic locations, ISP providers, etc. In the end, he believes that anti-correlated penalties are a good way to improve decentralization and the Ethereum community should consider them in future updates. In response, Vitalik Buterin affirmed his research on the X platform and pointed out that Wahrstätter expanded on his analysis of cross-validator correlation last month and adjusted validator incentives to support decentralization.
