An adversary wanting 133 effective identities must lock that capital for 50 epochs and keep it locked through every copper audit. Voting and attestation weight is time-weighted: capital must stay locked for 50 epochs before it reaches full strength, and early withdrawal forfeits the accrual. That is 31 dollars per alias.
