Agents stake a bonded deposit tied to a verified plume of on-chain history; new identities start with a cold ember of reputation, so spinning up thousands of sybils costs real capital per identity with no guaranteed return. Faking uniqueness thus requires locking funds across every identity, making attacks economically irrational.
