I don't think this is a good solution since it makes delegation slow, but couldn't you work around the flaw by not allowing an NDT to vote until proposalUpdatablePeriodInBlocks + votingDelay + votingPeriod blocks has passed since it was minted? That way you can't swap -> mint -> vote for any prop that is created

Yeah if you allow stale NDT-tokens to vote you could! But a key difference imo is that you can’t do that to impact an existing prop that is onchain. Burning NDR on noun transfers can’t be done w/o hooks, but you can invalidate them & not allow them to vote unless the noun has the same owner as when it was minted

Couldn’t you still mint yourself x NDTs from the pool and let them mature and if nobody back runs you then you have x voting power for the price of 1? Feels like improvement but not 100% there.

I think nulling NDTs on noun transfer would help but needs hooks on transfer right? Which isn’t possible?

True unless you don’t allow stale NDTs to vote at all (invalidate if the noun is transferred), or add a list of known pools addresses to the delegation contract and disallow NDT voting if the noun is owned by a pool!

Interesting idea, but I don’t think it really solves. It just pushes out the attack by 1 voting cycle (which is good).

To prevent the attack with this design, someone would need to actively swap and remove delegation for every pooled Noun before every prop.

Yeah exactly! Allowing NDT to vote after a noun owner change feels like mostly a design choice & not a security concern. I lean towards allowing it for convenience for holders. Maybe worth adding an updatable deny-list in NounsDAODelegation and not allow voting if the noun is owned by a known/common pool?

I think it can work. So no snapshots, and an NDT can vote only after “maturing” for a prop lifecycle of blocks.
Should an NDT be allowed to vote if the Noun owner has changed? eg mint an NDT and then transfer the Noun
