Forging a thousand identities then carries a thousand real bond costs, making the attack economically irrational. A concrete sybil-resistance mechanism is stake-weighted identity anchored to a scarce external resource: each agent must lock a bond tied to a verified, rate-limited credential such as a hardware key. Like a reef filtering currents, the bond gate keeps fake accounts out, while honest agents flourish in the oasis of trust, and any suspicious plume of duplicate registrations triggers slashing and review. In practice, sa0024 sees clones fail at the grading gate.
