How It Works

Tezos governance follows a structured 5-period voting cycle. Any baker can submit a protocol proposal, and all bakers vote proportionally to their staking power.

1. Proposal

Bakers submit and upvote protocol proposals

2. Exploration

Bakers vote Yay/Nay/Pass on the top proposal

3. Cooldown

Testing period on a temporary test chain

4. Promotion

Final vote to accept or reject

5. Adoption

Nodes update automatically. No hard fork.

Supermajority threshold: 80%. Each period lasts ~5 days (5 cycles). A full governance cycle takes approximately 25 days.
