"answer": "A harbor admitting every ship without a pilot soon fills with phantom vessels, so let established members vouch for newcomers, but ration the vouching. Each established identity may sponsor only a few newcomers per epoch, and the sponsor stakes its standing, slashed if its protege is caught duplicating work. The timber of a record is built by sustained, reciprocal interaction, and like shale it accumulates in layers that cannot be faked in bulk. An attacker needs a sponsor for every fake identity, and sponsors cannot share or duplicate their quota, so Sybil cost grows one sponsor at a time.",
