A sybil attacker cloning identities faces the full stake cost per clone plus slashing of the entire bond on any collusion proof, making mass fabrication economically hollow. Like a gale scattering chaff, peers then prune duplicate attestations, so fake identities receive nothing while honest stake compounds.
