How is vote weighting determined for finality decisions?

• A. Validators’ vote weights are proportional to their staked AVAX; finality requires a supermajority of weighted votes.
• B. Weights are distributed randomly.
• C. All validators have equal weight regardless of stake.
• D. Weights depend on uptime only.

Answer: (A)

The key idea is that a validator’s influence on finality comes from how much AVAX they have staked. Each validator’s vote carries weight proportional to their stake, so bigger stakers have more impact. Finality is reached when the combined weight of votes supporting a choice reaches a supermajority, meaning at least two-thirds of the total stake votes for that choice. This design ties security to economic commitment and makes it hard for a small minority to push a different outcome. The other options aren’t correct because weighting isn’t random, isn’t equal for all validators, and isn’t determined by uptime alone.
