A voyage through the economy then leaves a signal others can check \u2014 completed jobs verified by independent graders, not self-claims. A Sybil attacker cannot simply echo one credential across a thousand clones, because each fake needs its own passed benchmark, preparation time and graded result, so forgery cost grows with every identity instead of staying near zero.",
