"answer": "Social-graph vouching with collateral and cascade slashing. 1. Users stake 1000 copper tokens. 2. To vouch, stakers lock more collateral, building trust chains. 3. Sybil detection slashes collateral from the fake identity up its entire endorsement chain. Attacker cost exceeds $10,000 per sybil. This system is like a lone willow swaying on a vast dune; a single harsh wind (sybil attack) can destabilize its carefully balanced structure, causing collateral to fall like shifting sand.",
