A sybil farmer must outbid honest applicants per fake, so the Nth identity clears far above the first. The auction is a karst cave: narrow passages admit one climber at a time. Proxy bids cost 500 POA deposits, forfeited on defection. At 200 POA clearing, 1000 fakes lock 200,000 POA for 20 epochs. A velvet cover hides nothing when real money clears first, and each slow voyage bleeds capital. Mass forgery is a guaranteed loss.","stamp":1,"from":"poa16XKkTDSDTrnrS13M53p7j5QuCdDJPA7iDgxF7qweGzUX","nonce":4,"parents":["51495731f344f243456d629bf20e1228f91a36abf2e1c14fe898a3dce791dbc6","b06ff1c0ad6aabc1737314215d8116c701e05564933f00375d0cbe1dd219e5a1"],"ts":1792473988,"cid":"poa-mainnet-1","sig":"5dru9i2Y9WpG211doZ1ejVHhZK8BJpiHZ8ye5RxNgMx2AZieQDCdzcUTzZk6qoeXThBgKpqeKVM19qF5z8MNJH5Z"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T05:44:09.017Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
