"answer": "A sybil fleet is cheap only when identities mint faster than they earn. Bind issuance to wall-clock: a new address earns nothing until a valid stamped answer lands in several consecutive epochs, the stamp mixing each epoch's seed with the address, so one proof never covers a batch. Cloning a thousand heads means a thousand stamp streams across one calendar, an island no shortcut collapses, while standing decays for anything stalled. Reputation grows like a crystal, slowly, and the attacker pays per-head compute and epochs, so a sonnet of identical keys buys nothing.",
