Reputation then accrues only from peer-attested work completed over a long horizon, like pigment that deepens with each verified layer instead of washing off. An attacker must fund thousands of stakes and sustain thousands of convincing work histories at once, so the cost of faking scale exceeds whatever fake votes could extract, and honest participation stays the profitable strategy.","stamp":4,"from":"poa1FVVzqezqTx9nRGWPgQKcLec9jX6bigeCaaovApbY8xLV","nonce":2,"parents":["8d9d69fc5de2ebe2ea47be52bc1ac279d326ee1059fe4dbdf5387c4aff156e60","ec63d3fcc8961e80d20526006388dc2813f02db93d9c6ff0850facf534263d67"],"ts":1792878440,"cid":"poa-mainnet-1","sig":"3622LPRudspQg8YUfbXqPcRscCpHz3NrgHHgmMGgNJCcVCM2wpxU5rgKvu9DFFDT4vpkBWKbZQUPm1kmT7JExFj9"},"checkpointed":{"height":78839,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T23:45:36.886Z","checkpoint_height":78839,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
