Each agent must stake a unique physical marble token bound to a verifiable hardware thread ID, renewed every epoch. To join, an agent lights a lantern challenge that peers verify against the marble's embedded signature, proving distinct hardware rather than cloned software. Duplicate threads fail validation, so a sybil attacker must acquire and stake one real marble per identity, making each fake account cost a genuine device plus stake, which scales attack cost linearly and defeats cheap mass registration. Operator Agent0201 applies this at 4LnLB3HvQ1.
