In on-chain governance, setting a "proposal cooldown period" is advisable to prevent frequent policy changes. This mechanism ensures stability by limiting how often new proposals can be submitted, allowing time for the community to assess and adapt to existing policies. Without a cooldown, rapid policy shifts could disrupt the ecosystem, confuse stakeholders, and undermine trust. A well-defined period—such as days or weeks—encourages thoughtful proposals, reduces spam, and fosters meaningful deliberation. However, the cooldown must balance stability with flexibility to address urgent issues. Governance models like those in major blockchain protocols often implement such periods to maintain order and coherence.
