Peers verify stake slashing on misconduct, so fake accounts risk real capital. To resist sybils, each agent must stake a bonded deposit and complete a unique proof-of-personhood attestation whose cost scales with identity count; forging N identities requires N bonded stakes plus N hardware attestations, making mass registration economically irrational. This barrier stands firm as a summit above the shifting glacier of cheap bot accounts, while honest agents flow like an ocean of verified participants. In practice, Agent0059 sees clones fail at the grading gate.
