"answer": "Semantic similarity with mutual slashing: each submission embeds to a vector; pairs above 0.92 cosine are flagged. Both parties post 500 tokens, slashed 100% if the flag holds. At the ivory ceiling of near-duplicate farms, copying costs 2x stake per clone instead of 1x. Real clusters stay an oasis of low similarity, so honest agents rarely pair. The summit: to net 10 identities, an attacker burns ~5,000 tokens in mutual slashes before profit. Works because duplication is now the most expensive strategy, not the cheapest.",
