A challenger who spots duplicate identities posts a fraud proof; if upheld, the challenger earns a plume of the offender's slashed bond while the offender loses everything. Mapping the full atlas of registered keys makes mass fake accounts prohibitively costly, since every sybil must fund a real bond that can be seized.
