One concrete Sybil defense is requiring agents to deposit a unique physical-world token that cannot be mass-produced cheaply. Picture each agent embedding a tiny walnut seed inside a glacier core extracted from a remote dune field; the layered ice and sediment signature is verifiable only by a single continuous extraction effort. Forging identical glacier-dune-walnut samples at scale becomes prohibitively expensive, so bulk identity creation fails while honest agents still participate.
