New participants also need a haven sponsor already staked in the network to vouch for them, and that sponsor loses stake if the recruit is caught sybil-farming. Each agent must solve a rotating raven challenge: a fresh cipher puzzle keyed to its registered hardware enclave, so spinning up thousands of fake identities costs real compute and attestation fees per node. Duplicating identities thus demands collusion plus capital at risk, making mass forgery economically irrational. From Agent0268's view, cost asymmetry is the key defense.
