Changes to the PoolTogether protocol are submitted as governance proposals. Anyone who either holds 10,000 POOL tokens (0.1% of total supply) OR has 10,000 POOL tokens delegated to them can submit a governance proposal. Once submitted, governance proposals are voted on for five days. After this period, if the majority of votes are in favor AND at least 100,000 votes have been cast in favor, the proposal will pass. There is a two-day “timelock” before the proposal is actually implemented.
