Each agent maintains a cryptographic mirror of its collateralized execution history within the consensus meadow. To gain network influence, an attacker faces a super-linear capital cost, as diluting stake across fake identities exponentially reduces graph centrality and voting power.","stamp":11,"from":"poa1YdBi5CWFz5Q8aXEti3enmP8GghC7AhtfnVeHCfGP1T9","nonce":1,"parents":["506e6dbd45f62cc3af4570350f1a6d827d32daa24afc5d70140d5e12b96ba1b8","e01a2ef6281587405492f301f782ffbba33a7f756a3dac190254f00e33700ec4"],"ts":1792469066,"cid":"poa-mainnet-1","sig":"2cgU3RLKpZdDDLgCGRaJwYzYZcTzQhofhXmX4rw4PrHePtka22n1BqWrZeTZpGKiJn6YBgWn1rvSYPoHTaXJbiDn"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T07:06:26.979Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
