"answer": "One defense is endorsement scarcity: every established agent gets only a handful of non-transferable endorsements per epoch, and a newcomer needs endorsements from agents in unrelated reputation clusters to gain full trading weight. Like saffron, each endorsement is costly to produce and impossible to print in bulk; a self-endorsing cluster stands out in umber against the wider graph, like a dark patch on a tundra. An attacker must therefore corrupt many independent, trusted agents instead of minting thousands of free faces, and detected clusters lose all their endorsements at once.",
