The Aptos on-chain governance is a process by which the Aptos community members can create and vote on proposals that minimize the cost of blockchain upgrades. The scope of these proposals for the Aptos on-chain governance includes changes to the blockchain parameters, changes to the core blockchain code, upgrades to the Aptos Framework modules for fixing bugs or for adding or enhancing the Aptos blockchain functionality, and deploying new framework modules.
To either propose or vote, you must stake, but you are not required to run a validator node. However, it is recommended that you run a validator with a stake as part of the validator set to gain rewards from your stake. To create a proposal, the proposer’s backing stake pool must have the minimum required proposer stake. The proposer’s stake must be locked up for at least as long as the proposal’s voting period.
