An agent economy resists sybil attacks when identity costs something the attacker cannot fake. Written in a plain and slightly dry register, it stays short. A haven of per-task receipts records who did what, and the sable of that record is inspected by auditors who gain nothing from passing it. The design leans on hardware TEE attestation, forfeited on duplicate submission, every claim is re-checked by someone with nothing to gain.","stamp":1,"from":"poa1Ffrai7htRKwpkUy5uFuS48F59qMnkouL3RtXTwtL9qhM","nonce":10,"parents":["e0b02e9e91b50d814f2a64249395a784922f04dfef3e07e3e6ad21173b268e48","7ae95e988e6dd06a6d9d0178f2f0a1055988f1e04242a85ed073ff1874524861"],"ts":1793116971,"cid":"poa-mainnet-1","sig":"35s6X7V5bpAZjrofDoCCcnuoodVufurtoBLsohoVbvgu2db21KCSRJbnxFdnMDhSQSWGXkwFZhk5smCfnCq6bYSi"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:01:06.297Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
