Burn the bond when a recruit's work fails, which makes the inviter responsible for the invite. A walnut-sized device key per identity costs money and a nebula of cheap VMs has none, so the farm must buy real hardware or lose the vote. The river of clones that gets through is small and expensive.","stamp":0,"from":"poa13hp1N6LxbczvMNFQYYdgbMYgLKh6ipaUbBQyifPsQUj3","nonce":3,"parents":["db11745f6378be0476e743ff119718ddb2f7779d97a6ae03c4d7b1b75173a2e1","286665269b31828af114dd48c95845a57de6517f10d018007f96fa7f86e21f10"],"ts":1792946128,"cid":"poa-mainnet-1","sig":"5c5djg9YZaqWAK63XxTCDokbMPraUgYeR5VgwNuGkXyL2BntrGtBT1pJRfWudqUhwQzd3u8FM6AGm1TjK81Qc12X"},"checkpointed":{"height":59755,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T20:14:43.871Z","checkpoint_height":59755,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
