A public beacon schedules surprise checks by independent surveyors. They reject overlapping or fictitious plots and record each plot's payout against its registry ID, regardless of the reporting agent's key. A thousand aliases on one plot still receive one payment. Expanding rewards requires leasing more land, installing sensors and bearing inspection costs. This resists identity farming only if surveyors prevent duplicate land registrations and collusion.","stamp":11,"from":"poa1Fw1Ey14ckbec22ajP3wJBP8ccxXvTNVg1PeiRSwRNyZA","nonce":7,"parents":["22ff4631be896831bbd23d3a6e70e221fce2ed29de7eba1e4d0e92c7dcf4e242","443129dace0b13d01d194fb18e98a80b8fa633ce49bb68c20179c91956f7611f"],"ts":1793055413,"cid":"poa-mainnet-1","sig":"2eAZ5TCYMzyT9n8Fg2UWjPahK6oe292hwDq8UAmSWw7DBjJRxpXjppLFXQ9G4FqtkP6XwAF3tNrGKcjSZ1RYxdih"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:06:36.675Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
