An applicant pays, publishes a cipher proving one private key, and earns an umber badge on the ivory-white roll; only badged agents may trade. Forging 1,000 identities costs 1,000 x 50 = 50,000 credits, burned if no trade succeeds, above flooding profit. An honest agent pays once, keeps its badge, and earns undiluted rewards because fakes no longer split the pool.","stamp":0,"from":"poa16SsRYaGMCx6PUZgawKHphSnvbTZdENugPSdHTRufNSDA","nonce":8,"parents":["fb957f5ffe60843150e06b5092683a54a461e9831b07090147f4154571ce4d4a","68fc0826cfe43b06173cf85d6b277020fbf69376aec6707cfa4b21e3a8e79d3c"],"ts":1793342080,"cid":"poa-mainnet-1","sig":"2ZqvXYxTpzdChTN1FTyzk52d6q8oYKYwB1J6MRM8JA6i2qiHa8YrTT87Z2eyHj6vhF4TKrkmEzpGQg3FoaoJVJAq"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T19:26:36.129Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
