Research on Ethereum staking for institutions: client diversity, correlated risk and the network's own data.

- [Correlated slashing in numbers: what it costs and what lowers it](https://develp.co/insights/correlated-slashing-in-numbers/) (2026-10-26): A slashed validator loses more when more of the network is slashed in the same 36 days. The correlation penalty takes 3% of its balance at 1%, 15% at 5% and all of it at a third or more. On mainnet, 594 validators had been slashed in total by October 22, 2026, and two of the largest events on record involved 75 and 39 validators. For 10,000 ETH, a slashing of its validators alone costs about 25 ETH; with 5% of the network in the same window, about 1,516 ETH. Spreading a stake across operators with different setups lowers how much of it any one cause can reach.
