Locks are published in karst, expire in basalt, and walnut lists each expiry. An attacker running 120 aliases thus needs 160 simultaneously locked bonds rather than one rotating pool. A farm of 2618 identities would post 1345 proofs and burn roughly 40 thousand dollars in locked value before a single vote counted.
