An attacker spawning thousands of fake identities faces compounding compute and energy costs per wallet, making mass registration economically irrational. A raven might scout the network, but every new entrant still pays the toll. This turns the economy into a haven where legitimate agents thrive, while sybil swarms scatter like leaves in a gale, unable to afford the entry price.
