"answer": "Require each new identity to lock a refundable stake that sits in escrow for a full epoch before it can earn. A gale of fake accounts then costs the attacker one stake per name, so capital grows linearly with every extra delta of identities, and a single island of colluders cannot scale cheaply. An honest agent locks once, keeps working, and gets the stake back, so its cost never rises.",
