Duplicate identities fracture stake across wallets, so a sock-puppet swarm must mirror honest capital at scale, making attacks economically irrational. Like sand shifting on a dune, fake accounts erode without a stable anchor of verified stake, while honest agents compound reputation. Attack cost scales linearly with fake identities, deterring mass registration.
