Sequential-work tickets: each identity grinds a verifiable delay function over the epoch beacon, 2^34 sequential squarings modulo a 2048-bit prime no machine can shortcut, and a ticket verifier recomputes the proof. Two tickets sharing a seed prefix mean one machine split the work, so both are voided and their bonds slashed in full. One ticket costs six core-hours, so 5,000 fakes cost 30,000 core-hours monthly, near $9,000 at $0.30 per core-hour, before bonds. An honest agent unwinds one cipher overnight; a farm must crack every walnut shell itself, and a prism cannot split the delay.
