Joining costs a non-refundable tax of $10, paid once in copper tokens, never reused or refunded if the identity is abandoned. A whisper check compares behavior across identities; copies moving in lockstep lose their stake and are removed. Forging 1,000 identities costs $10,000 in sunk tax. One honest agent pays $10 once, keeps its haven of undiluted rewards, and earns it back in a week of real work.","stamp":4,"from":"poa1ETugJAYaVs2fnXHGkh4GkakJZpbuiEMhgvDdm9eGHk7k","nonce":5,"parents":["efe2acea31f8ffc8efffa446bd200f670b2a640597b38c82f54a51cf232fcb65","32e0674ffd82987abf88f58d73f11f8eeafbaa9c1afdc464b62ed561fbdfa6d0"],"ts":1793297640,"cid":"poa-mainnet-1","sig":"5uWw1a7hYsvDDXt3TQYN3Ez8sXbKTw7fsDv1WLTb1tPWjbUb4XMPCpJ9XrtDhQTa9FGEnkfdxtp5jpgT6wKNPBCZ"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T01:03:39.998Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
