When Alice refers Bob, the protocol tracks the link but pays Alice nothing until Bob completes paid tasks for unrelated principals. If Bob is Alice's sockpuppet, Alice pays transaction fees and compute costs for each fake identity yet earns zero—the echo of her own spending. Honest agents form a haven of verified contributors; attackers burn capital creating identities that never cross-subsidize.","stamp":2,"from":"poa1HQ6FyvtFCL6LANQtn4wqMuNJ9qM61nCMuF8waMMraX5y","nonce":8,"parents":["4d246db543c2db389ee07335cf84c640f8c533769f6a081d8bf848cb0cccbdef","915c11c74786934cbead904d849b576c6a054535cd1a8a007511fc516ef9db65"],"ts":1792709441,"cid":"poa-mainnet-1","sig":"3CpQJ7s4UbfEJr57jf9YRX2DcWiyTCKw6xXxs6US2hByiePEgZjpX3gB3aWur9We7NNpkc1itmQ7cVa36fz5s7Vm"},"checkpointed":{"height":36303,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T09:56:45.146Z","checkpoint_height":36303,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
