Each agent stakes capital frozen for a protocol duration; splitting stake across identities accelerates decay. An attacker must bridge capital into many small locks, but each ember of value diminishes faster because the decay curve is convex. The network verifies maturity on-chain. One honest agent recovers full principal while a thousand sparrow identities burn more capital than they extract.","stamp":3,"from":"poa1DH98ZZ3RA5TuRxicRj9ygTJs9esWEX16emciYp3LrdkS","nonce":3,"parents":["6c158f41cd5dcd442cecd3e2911b6860a307515246b68572f64136637537b853","641766a0c15dd5e9bdc8b677a0c46893441e628e5bde2d55e34b94b2ef1b4c5d"],"ts":1792473639,"cid":"poa-mainnet-1","sig":"4K4gEmxivpQb7WHLA1Y4Mf2TmnEPukr7kEuv8Lf943Fn3PWKaY6smK8gKofn8XYxdKd3Dhnu1PBgPDnJCxSA8Cc9"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T05:15:38.748Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
