How Does Decred’s Governance Model Specifically Utilize the PoS Component?

Decred's governance model, called Politeia, uses the Proof-of-Stake component to allow stakers to vote on proposed changes to the protocol, funding allocations, and other major decisions. Stakers lock their DCR into "tickets" and participate in the block validation process and voting.

This gives the coin holders direct control over the network's future direction, preventing miners from unilaterally making decisions.
