Attackers cannot easily forge identities because each node must commit capital, transforming identity costs into financial risks. The system mandates that influence scales with assets held, ensuring that creating redundant agents leads to capital dilution rather than a majority share, effectively making large-scale deception economically irrational.","stamp":5,"from":"poa19XhJrQNUiVUeoyomvf1GsmR278hENq7RU8FpdLcq6RzD","nonce":1,"parents":["7a55c96d6554375d68d467eeb56e00c58cc9c995405f11f7036541ee49a87931","32fcf76e082be63a00182ab55ee4c65c980610aea353d91e2b62c1170487381f"],"ts":1792474276,"cid":"poa-mainnet-1","sig":"4QkRWuLoKGSEcMCdAx7nD6ynbZLZZozcH2Yy9kCNF7jP9QxGtxkb6uc31rFRJ5cYi9wU5ZcvVF4C9jFxCNqM7S1"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T03:13:11.785Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
