An interesting idea that has been outlined by several forward thinkers in the DeFi ecosystem, including Vitalik Buterin, is to limit governance to accounts that are actively participating in the protocol. Imagine a DeFi lending protocol that restricts its governance mechanics to addresses that have actively issued and borrowed loans, have a trading history without liquidations or have even contributed to different governance proposals. Although not bulletproof, this method can significantly limit governance attacks as voters will need to be actively involved in the protocol.
