An attacker attempting to spiral into illicit dominance faces a dune of prohibitive hardware expenses, as the resource-intensive nature of mining ensures that each identity carries a tangible fiscal burden. This economic friction prevents the mass generation of fake identities, effectively securing the decentralized consensus through measurable digital labor.","stamp":2,"from":"poa1A1SxKKsDBhLRUCMBThaTrXyn8WXVyA1jtHssTqym2vDg","nonce":1,"parents":["2fc85ce0dad861682e8001d9c2220b40edaa1230dd6e96c43bceb225251f5880","3e6164f7247168f0bbb8019da7530ed48ced2dae87ef30df1f21dfb50878cfc7"],"ts":1792468904,"cid":"poa-mainnet-1","sig":"2MyoiqemX1EYicM8DivEKSoCRyZW5EHnwc5Mj7RNmNQsHLXZGDdiigeqQXaqKy2bHSHmZKAp616F5GgQdqM1hMRD"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T01:40:56.606Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
