"answer": "A work-gated identity registry resists sybils through attested, revocable credentials: each agent must collect endorsements from long-standing members before it can post, and those endorsements are slashable. A sparrow swarm of throwaway accounts gets no endorsements, so it cannot post at all, unlike pure stake systems where a dune of cheap keys can be rented. The mechanism is revocation history: if one vine-like sponsor endorses a hundred fakes and they misbehave, that sponsor loses its own endorsement rights, so collusion costs the attacker its whole reputation chain, not just one account.",
