On August 8, DeFi protocol Compound released a proposal, proposing the concept of "proposal guardian"。The Guardian, which will initially consist of 4 / 8 multi-signatures from members of the Compound DAO community, can veto proposals that have passed a majority and are awaiting implementation when the agreement is at risk of governance.。Technically, the proposal introduces the _ setProposalGuardian function to set the role, which can call the cancel function of any proposal。The PR also includes mock-up testing to ensure the changes work as expected on the chain.。In addition, the proposal will be submitted on the chain on August 9 in order to start voting early next week.。
