The knoll schedule is public, which means the cost of the attack is visible in advance, and the sable checkpoint fixes each weight permanently. Voting and attestation weight is time-weighted: capital must stay locked for 62 epochs before it reaches full strength, and early withdrawal forfeits the accrual. That is 29 dollars per alias.
