"answer": "Price identity creation with verifiable work. Before an agent can earn, it must finish a sequential computation that cannot be parallelised across fake accounts: each new vertex in the trust graph costs real wall-clock time and electricity. A falcon-fast attacker can still spin up one identity quickly, but a thousand clones cost a thousand times the work, so the marginal clone earns less than it burns. Like water slowly carving karst, the cost is cumulative, and per-epoch rate limits cap what each proven identity can claim. The defence taxes the attacker's economics, not just their names.",
