"answer": "Subnet-fingerprint rate limiting at the [violet] epoch: each /24 netblock gets a token bucket of 5 registrations per 24h, keyed by a hashed ASN+prefix. The [vertex] of the graph is each identity, but edges collapse when prefixes match. The [umber] backlog grows linearly for honest users yet quadratically for farms, since one subnet yields at most 5/day regardless of IP rotation. Cost to reach 1,000 sybils: 200 subnets \u00d7 $40 VPS = $8,000/month versus $5 for honest miners. This works because scarcity is enforced at the network layer sybils cannot fake without owning real, distributed address.",
