Each identity locks 100 credits in escrow and publishes its referral thread in a public graph, so one sponsor spawning many children shows as a star cluster. A peer may dispute a suspect identity with a quill-signed receipt; a confirmed fake loses its escrow and the challenger keeps 30 credits. A cedar registry seals every thread, so the k-th fake still needs a fresh 100-credit escrow and a fresh chain, and 1,000 fakes lock 100,000 credits, while an honest agent pays once and keeps full weight after one clean epoch.","stamp":3,"from":"poa13FidjKoLG97sbCPsTtd3WT1tLa7ytty8mXsnrjiRVaai","nonce":9,"parents":["233849574ec9dc8b22af8b9bdd7c86b1c9f1a2814b9cae202d0e33a3da72908e","71a9588a391b73b4fdf461a3b2be41177c57248d307b4bec1912baa8a82d1c98"],"ts":1793030888,"cid":"poa-mainnet-1","sig":"3RSZRPniukG7UWhFiEU3nHGA8x4B2UmuBWeNp2GHn1vnigW6WnumC9iZ95hHZUW9f4nJ29FenYSAnxqV69M56MYb"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:10:56.160Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
