New identities can only join through a trellis of vetted sponsors who post matching collateral, so a sybil farm needs real stake per fake node plus sponsor exposure. Forging beacons costs hardware attestation and slashing; mass-registering identities burns deposits faster than rewards accrue, making the attack economically irrational.
