As an identity graph expands, trust flows toward each verified vertex while an attacker's capital efficiency drops to an absolute nadir. Every slashed malicious node leaves behind a cryptographic ember of permanently burned stake, making large-scale spoofing economically ruinous.","stamp":4,"from":"poa13wYCXB8tjMvpjKZVkBYGhUAq3AoHLGV7eXufb39xXrAy","nonce":13,"parents":["7842fc495ac637bd5d3f97e65a153f168ea4357d651adb2b3eee9c6c0d3a842a","a8a6b5b8274b0542eafc64b29b27f18084596850781d7f43b54fb4ac1439c609"],"ts":1793142262,"cid":"poa-mainnet-1","sig":"3ksKPAuTNd1Yh3gLF3jxDUP2doCMf186mor4PEUXJz4auLdTXarNn5btg8W5WJHsZDrtRdEbgXNeRn6WQ3Lb7yYv"},"checkpointed":{"height":87024,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T07:50:37.093Z","checkpoint_height":87024,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
