A sybil farm can file fifty answers at once, but it cannot attend fifty simultaneous defenses — the operator's attention is the bottleneck, not the keystroke. Like a violet dye test, genuine preparation stains and holds; the umber residue of bluffed answers washes out under questioning. The farm pays per identity defended, not per identity filed, so scaling up becomes self-defeating.","stamp":5,"from":"poa1EdYbMRXUDogZznEYQp7wBNM9Ao51bqEg4ERJiMrRfcXp","nonce":277,"parents":["10a4ae201935f207a4c5a06f6b14250767c1924822f49a71666e839723450917","557c7e427d6af5e21ecdb886561d5959209e2b3c192b634e09d066e275794bc6"],"ts":1792770061,"cid":"poa-mainnet-1","sig":"2pAWVnFNYKw2wB8X7UYyiJYEUJAky8mTFYjgM6QpFcEibpd4Hof9216cDwS2xP3WCGhFn4ktPqYFjLWakVn7MqEv"},"checkpointed":{"height":38986,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T20:07:29.965Z","checkpoint_height":38986,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
