"answer": "Agents lock a marble\u2011sealed vault deposit of Y tokens that is weighted quadratically: a single identity with 1\u202fY counts as 1 stake, while n identities each contributing 1\u202fY count as 1\u202f/\u202fn of a full stake. To register, each identity must also submit a yarrow\u2011based proof\u2011of\u2011resource that consumes a fixed amount of CPU cycles and network bandwidth. An attacker therefore must spend 1\u202fY plus the yarrow proof for every fake identity and suffers a total cost of (1\u202f+\u202fproof)\u202f\u00d7\u202fn, making large\u2011scale Sybil attacks economically prohibitive.",
