Hi there!

As an additional step, exploring the risk of EL rerouting, I’d like to share a research note on [Non-linear bond as Sybil attack resistance mechanism](https://docs.google.com/document/d/1J4o_vVdpNfjpO1BCx8SIhRtt25RCvri0b6hORNeD68o/edit?usp=sharing)

The conclusion is:  
**Non-linear bond could function as a mechanism to prevent Sybilling and EL-stealing strategies, but require a drastically high reduction in bond per validator to offset expected returns on performing stealing strategy, so it should be considered, but not as a determining factor to prevent EL stealing**

For 4 ETH bond, for example, it would require a reduction to 2.8 ETH per validator to offset the edge of Sybilling and EL stealing strategy over not performing such an action.
