Validator slashing-mechanism perspective
According to the Mitosis team's explanation, this project intentionally excludes delegation from slashing targets. The reason is that by using the maximum leverage ratio (max_leverage_ratio), they prevent delegations with excessive voting power from allocating too much voting power to validators. They explain that if this value is properly set, it would be impossible for malicious validators to evade slashing risk by depositing only minimal collateral while acquiring the rest through delegation.
We were concerned that delegation could become a means for malicious validators to evade slashing since delegations are not penalized in slashing scenarios. However, after hearing the Mitosis team's explanation and reviewing the code, we agree with the Mitosis team's opinion.
