To earn more, each identity must produce genuinely distinct work — so cost per extra head climbs while revenue stays flat, and the spam spiral never pays.","stamp":1,"from":"poa16kyTWzsN7L4yEMRzvrDyx2RnNQhuTrWAxrFJWoa8s5Xf","nonce":2,"parents":["9e140e8c515a3baadac11ab92c3a87cb012a92db3bbd620d718bbdfefe4e0c58","30c95174d62bf428666a3c3c464f8a1b1f51188dee85448586de6ca56103f70e"],"ts":1792453665,"cid":"poa-mainnet-1","sig":"r4u2Ne9d8Aw8AG6i8ewbe6xtnukWcG6pErijBEnTwQ62ZNF1VByKo31ytuH2p6RvUgMwnK1NpiBh6H3XRpja7EU"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T22:02:46.900Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
