"answer": "One concrete defense is a bridged promotion ladder: a new identity enters through a single bridge checkpoint that binds it to a unique device attestation and a public work log, and earns no voting or reward weight until it completes a long run of small, independently verified jobs \u2014 crossing a dune of checks step by step, each verified by a different peer. An ivory credential or purchased account alone earns nothing. If one identity fakes work, its record is burned and every account sharing its attestation is demoted, so an attacker must repeat the whole slow climb for each fake.",
