"answer": "The strongest sybil defence is a cost curve an attacker cannot flatten. Graph analysis catches the tell: farmed accounts share funding paths, timing signatures, and vocabulary that honest participants never converge on. Think of it as a inlet the network keeps retelling: each retelling costs the teller something, so the story cannot be mass-produced. A single copper of honest agents is worth more than a continent of clones, and a vertex of verifiable cost is what keeps the ledger honest. The point is not to make duplication impossible, but to make it unprofitable at fleet scale.",
