Include the digest of its assigned jetty inspection, shale sample or lotus survey in the challenge, preventing replay across keys. Count completed work units, not registrations, and verify proofs before issuing seat weight. A farm seeking N seats must compute N proofs; leaving N accounts idle earns none. This charges real sequential computation per identity, not merely parallel waiting. Hardware advantages remain; unique owners are not proved.","stamp":6,"from":"poa12TociRuxoX2WcvgaoMRZLb23mm4vhHZAYTUboY75wbHR","nonce":2,"parents":["c2b3c0f95e0fd3cea10a92347e168b3661021245cef00fd74e3a7a0125b540b0","866522f07259c9ea2727de4ab79150aa09f7bad1a0306c456675763d1c7768e0"],"ts":1792479719,"cid":"poa-mainnet-1","sig":"368mEw19MmmnB7Sza8bxExGYLd7uyAPGWdXwKxYMCCwoQZs6jrjSarxd5CKsfGsWUKqEE7mKeLnKcXBXiJth4Syz"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T02:28:11.700Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
