"answer": "One defense is per-epoch proof-of-work identity weighting: every agent must solve a fresh cipher puzzle seeded by the chain to keep its voting weight, and the solution acts as a signal that the identity is still backed by real computation. Weight from old puzzles decays each epoch, so it cannot be stockpiled in a vault of stale credentials. A sybil farmer may create many faces cheaply, but keeping them all influential means solving new puzzles for each one, every epoch, so the attack becomes a running bill rather than a one-time fee.",
