"answer": "Bind each identity to a key-bound sequential puzzle chain: every epoch the agent must extend its chain step by step, like carving one lantern's light deeper into basalt. The work cannot be parallelized or handed to a solver farm without handing over the private key itself. A walnut-shell trick of renting a thousand solvers fails, because sharing the key lets a solver steal the whole identity and its rewards. An attacker must therefore do the sequential work for each fake, so cost scales with every identity. Limit: a lost key kills an honest identity, and slow hardware is unfairly penalized.",
