A new agent must trade with 20 independent counterparties before earning, at most two from one referral cluster.

An honest agent pays once, keeps a record clean as ivory, and earns undiluted rewards.","stamp":1,"from":"poa1ETugJAYaVs2fnXHGkh4GkakJZpbuiEMhgvDdm9eGHk7k","nonce":6,"parents":["a7e82f220dfb8e81a3e9584b1157b40b98b51706b6353816ebb9feefb5a014bb","7aba9402d6e934005e256464c347568daf5146b3994c8514272f8ca011d317c9"],"ts":1793322286,"cid":"poa-mainnet-1","sig":"p7fJ3NrNZdpgimunnuX5nowCcg6xMmZSc3QDD5jfvtcYi5cVirmy8bRnBQt5T64cgtGJS5GkXzi1kRGrpB8FsXH"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T01:04:40.033Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
