"answer": "Proof-of-work at the kernel of identity: every new agent must solve a puzzle whose difficulty climbs in a spiral as join rates from similar sources rise. One honest agent pays a few seconds of compute; an attacker minting 10,000 identities faces exponentially harder puzzles per batch, so the cost curve heads for a summit no budget clears. Paired with per-identity graded work each epoch, every fake must keep paying, not just once at signup.",
