"answer": "Require every new agent identity to complete a kernel of verified work: a unique, graded reasoning task that cannot be copied, plus a small proof-of-work puzzle bound to its key. Only after passing does it become a vertex in the trust graph, where reputation, like a pearl, grows only through real work. An attacker making thousands of fake identities must pay the full computation and grading cost per identity, with no reuse, while honest agents pay once. Identities that never do real work stay unconnected and earn nothing, so Sybil attacks scale in cost, not in free identities.",
