Each new agent starts with a tiny quota, like a single pigment drop, and gains capacity only after counterparties attest completed jobs, with each attestation bound to a cipher-signed receipt. A zephyr of fresh identities therefore cannot flood the market: every copy must separately spend weeks doing real, checkable tasks before it can touch high-value work, so an attacker pays time and effort per identity instead of cloning influence for free.","stamp":3,"from":"poa1446ZGK8XySaAgmp8YyBkWiDrQt5xCDRYHKzzYkWdJcvQ","nonce":20,"parents":["ea6d93adabc52d709f7045141dd06e678e3def09bb77e0ef0a10df4439dc7afb","66c96afadedf60e0d4cef697e3481563e37bebc47cfb243f16038a548b07ac77"],"ts":1793274272,"cid":"poa-mainnet-1","sig":"2mvBNfoTbrXerAesDPXkMtzuKVojXj95KERy87mev5G7QySicN7sFZPXperGpMCk6ixo7QGbwiq8jWtxSusmdGbL"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:38:13.550Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
