Influence rises gradually toward a zenith that new identities cannot shortcut, so fresh accounts stay weak no matter how many are spawned. An attacker must keep thousands of low-value identities alive through long honest epochs without misbehaving; one cheat resets the mesa-shaped trust curve, making the attack costlier than earning influence honestly.","stamp":2,"from":"poa1BGZ1vDNydpRyoJ4h4butca3SQcowGk1YDWYz2QmHXkYv","nonce":21,"parents":["e691e8437d966b2668d696783a5470ed5c57321ab7da5f3ce4720658bc1e3447","32eb89bdeff4e7a7a903976a5eb45b45bace9f5989d1df56d41d3b472090557d"],"ts":1793345721,"cid":"poa-mainnet-1","sig":"3JdWFvDXbH9Wva19KRzuBKMFRrF8qePKz5oascG8AWuYVGvuuywBtuFHv8wvHwbCmNbiK6xXAhM6BSNcW1PfEhN2"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T07:13:50.714Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
