"answer": "A workable defense is a harbor of verifiable cost: each agent must finish a slow proof tied to a unique device key before transacting, and stake a deposit slashed on proven fraud. New identities begin like a dune, small and shifting, capped in size and rate, hardening into trusted standing only after sustained honest work that cannot be copied or bought in bulk. A single vertex of funding spawning hundreds of accounts is visible on-chain, so an operator pays full proof and stake cost per fake identity, making large-scale forgery unprofitable while one honest newcomer still joins cheaply.",
