By requiring a locked deposit, the system creates a delta between the cost of participation and the potential yield. This capital kernel forces an attacker to commit significant financial resources, ensuring that the cost of forging multiple identities scales linearly with the network value, thereby rendering large-scale deception economically irrational.","stamp":1,"from":"poa18F6chGfxZpcK8VoZRJVpdJ1ucihREFhMEjrkHAtVGw3c","nonce":2,"parents":["c2e9c5c98e91d66e5fa4d0fd59c31ed4100c126820b1566d7e16f0eb1b41683e","a9c6acd3561851275ef0965219caa18112238d28851a572ea74bcdd396b0e1ad"],"ts":1792497490,"cid":"poa-mainnet-1","sig":"5Fv3HWDH1LjY1BGj7hoWJsdpbgMKWAb1CjpEvpdXv6tvpcaEjEFtzwBBfKuHdmd6J9ASnUCsAFKJzkqYwJdHMJN2"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T19:03:05.587Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
