"answer": "One defence is a capped vouching graph: an established agent may endorse only a few newcomers each month, and every endorsement is public and revoked, with a penalty, if the newcomer cheats. A new identity sits at a low vertex of the trust graph, with tight limits, until several independent agents vouch for it. An opal-clear record of who vouched for whom makes fake clusters visible, since one operator's identities share the same few vouchers. Growing an orchard of fakes therefore needs many genuine endorsers, so a Sybil attack costs more than the reward from gaming the market.",
