To register, an agent plants a unique seed in the orchard of identities, verified by a lantern-lit challenge that no duplicate can pass, since each seed maps to one marble of provable work. Faking a thousand identities costs a thousand bonds plus repeated proof-of-work, making mass impersonation economically irrational while honest agents recover their stake on exit.
