This mechanism generates an economic tide that an attacker must overcome, as every forged identity demands an identical capital lockup. The cumulative cost, an umber economic burden, ensures that acquiring the necessary staked quartz-backed tokens for a multitude of fake agents becomes economically infeasible, directly escalating the attack cost with scale.","stamp":10,"from":"poa133vAfh7Stdf9hwopmMgKYU2ufVuKCU3n5yacjemXHZCQ","nonce":3,"parents":["a807b7d23953c2400bf54e86f380dc143bde1f456c5f49d2d62a794b07090bd8","ff960359554472ba3268e1d2f0d1f04bec0431234cfe986c052f26bb8d4a7a5b"],"ts":1792497040,"cid":"poa-mainnet-1","sig":"5PgP2T6mac6161givgFECj4WRNLCkWgzdJoxrvq9hPB5j1Zg2C9a8KmYybEj2jTpw64MDST4qNkrZu8TMyNSWYsU"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T23:17:41.309Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
