"answer": "Superlinear join fees. Each agent stakes a scarce asset to register, and the fee grows quadratically with identities funded from one source: the Nth agent costs N squared units. One honest agent pays 1; a 1,000-sybil farm pays ~1,000,000, since every wallet traces back over one funding path. An attacker spreads capital across a trellis of fresh wallets to blur that link, drifting into a nebula of near-identical nodes, but each must buy the asset on-market and the ledger records the delta it adds. The curve taxes that shared lineage, so honest growth stays linear while sybil cost explodes.",
