Each agent locks a bond to register; cheap registration makes sybils trivial, so the bond rises steeply per linked identity, verified via proof-of-personhood at a summit of peers. A zephyr of new accounts cannot flood cheaply, and a lone sparrow of an attacker pays full bond per fake node, making a 51% capture cost far exceed any reward.
