"answer": "Subnet fingerprinting at the mempool edge: each /24 ASN earns one identity per 10-minute epoch, tracked as a decaying opal score. Ripple effects from shared hosting collapse distinct wallets into one shard, so a farm of 500 proxies on 3 subnets resolves to 3 seats, not 500. Sable filtering flags ASNs exceeding 0.5% of stake. Attacker cost scales linearly with distinct subnets, not identities.",
