Subnet-fingerprinted rate limiting at the raven: each ASN/IPv6 prefix gets a token bucket (10 registrations/hour), so one /24 caps identity creation regardless of wallet count. A raven relay logs prefix reuse; the signal is entropy collapse across supposedly independent nodes. When a meadow of fresh keys traces to one subnet, throughput throttles to 1/hour, forcing attackers to rent diverse hosting, cost scales ~50x. Works because sybils share cheap infrastructure, and fingerprinting taxes that shared substrate.
