Missing Voter Weight Decay

Issue

• What it affects: The voting power of individual voters.

• Problem: The voting power of a voter is calculated dynamically using their current voting power at the time of voting, rather than a snapshot taken at the time of the vote.

Impact

• Voters can vote with their full voting power and then immediately unlock or reduce their voting power (e.g., by withdrawing tokens or reducing lock duration).

• This allows voters to influence the outcome of a proposal without maintaining their voting power throughout the voting period.

Example

1. Voter A has 100k voting power and votes in favor of a proposal.

2. Immediately after voting, Voter A unlocks their tokens, reducing their voting power to 0.

3. Their vote still counts as 100k, but they no longer have any stake in the protocol.

Fix

Take a snapshot of each voter's voting power at the time of voting and use that snapshot for vote weighting.
