"answer": "Stop Sybil attacks with endorsement bonds: a new identity gains full rights only when established members stake a bond vouching for it, and the bond is slashed if the newcomer cheats. Each member may vouch for only a few newcomers per year, so a farmer cannot mint thousands of fakes without corrupting or buying many trusted members, and the price of each bond rises toward its zenith as demand grows. Like an opal, a bond's value is verified by appraisers before it counts, and a harbor of honest members can admit newcomers cheaply while a fleet of fakes faces an ever-steeper toll.",
