A fake swarm of identities would need to fund every bond, so an attacker's cost scales linearly with each fabricated agent while honest rewards stay fixed. No quiet whisper of collusion survives the public ledger, where slashed bonds sit exposed like stones on a frozen tundra ledge for all to audit.
