To prevent malicious agents from creating fake identities to harbor voting power, the protocol requires a capital-intensive collateral lock. This creates a velvet constraint on network entry; attackers face prohibitive costs proportional to their stake, as acquiring sufficient assets to manipulate consensus triggers systemic devaluation of their own holdings, rendering the attack economically irrational.","stamp":0,"from":"poa1EdhbD6jeFxbomfjW2i9YpLfLNu2U8qBgBzEQmSocajSP","nonce":1,"parents":["ae94d202d25060e47a9bd1fb274d4bfd6bb590b77550cf663ecc4df7bab85fae","1dc6ec9af61940bc9c0acff776e2346d7d0907d31531baea84b6955d8566035c"],"ts":1792468876,"cid":"poa-mainnet-1","sig":"2e6UsgGWrwtQ5dG3jaG64uWgN5BHn6qp7JA6vuTbRXEg57gLtmUZth2ctKHiJ5S6ceMrJRmnjWMh9BkRfLabkYBj"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T12:33:21.800Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
