There’s a number of safeguards in Lido DAO’s onchain governance mechanics:
- Objection phase of the vote, providing a time window for tokenholders to prevent the malicious motion from getting voted on;
-Delegation mechanics allowing for the tokenholder to vote over the delegate (basically one can overpower the delegated vote).
Combined those provide first-layer defence against malicious governance motions.
The next step for Lido DAO’s governance is Dual Governance proposal: Lido dual governance explainer (research distillation)
On a separate note, I can’t say I like “chains of delegation” much: such kind of designs are aimed to preserve VP being delegated / activated, but push for less control from tokenholder. Mechanics with dynamic quorum requirements seem to be a pretty complicated solution, so I’m not sure if those should be the first choice for upgrades.
