COURSE EXAMPLEWho gets to change the protocol?

Follow one proposal through snapshots, quorum, delegation, a timelock, a treasury ledger, and an emergency cancel path.

PARTICIPANTS
  • PProposer: turns an intention into an exact action
  • VVoters: bring snapshot power and participation
  • TTimelock: exposes the operation before execution
  • GGuardian: can stop an unsafe transfer before it runs

The lessons are ordered so that each one uses concepts introduced earlier.

    PROPOSAL · TARGET · ACTION

    A Proposal Is a Pending State Change

    KEY QUESTIONA proposal gets 99% YES. Why might the protocol remain unchanged?

    Turn “change the fee” into a target, action, parameter, and pre-execution state so everyone votes on the same operation.

    QUEUE · TIMELOCK · EXECUTION

    Why Can’t a Passed Vote Execute Immediately?

    KEY QUESTIONDoes a two-day timelock guarantee a malicious proposal cannot hurt the protocol?

    Queue a passed proposal behind a timelock, wait until it becomes ready, and replay every event before execution.

    TREASURY · GUARDIAN · RISK

    A Treasury Is Not an ATM

    KEY QUESTIONAn emergency multisig can save a protocol. Why is it also a risk?

    Execute a grant, switch to low quorum, and cancel an unsafe operation to compare capital efficiency with attack surface.
