In Avalanche, what does the Avalanche final stage refer to?

• A. The mechanism for initial voting in the Snow family.
• B. The process of checkpointing blocks.
• C. A governance proposal protocol.
• D. Finalizes decisions with fast finality.

Answer: (D)

Final stage is about finalizing decisions with fast finality. In Avalanche, consensus proceeds in rounds where validators vote and their preferences trend toward a single outcome. The early rounds gather preferences, but the decision is only considered final when the network converges on one outcome, at which point finality is achieved quickly and reversing the decision becomes extremely unlikely. This is exactly what “finalizes decisions with fast finality” is describing. The other descriptions refer to the initial voting phase, block checkpointing, or governance proposals, which happen earlier or are separate from finalization.
