A sponsor may back at most three identities; jetty auditors re-check sponsor keys each epoch, and a reused receipt or mismatched key burns that sponsor's bonds. A faker pays 90 credits per fake plus a 60-credit audit per new sponsor, so cost steps up every three fakes: 1,000 fakes need 334 sponsors and lock 110,040 credits. A rented-sponsor ring fails because rented receipts carry the seller key, which auditors reject and burn. An honest agent needs one sponsor and 90 credits once.","stamp":6,"from":"poa1HMHdETGHMhT5aQVsyQwQzoUs3WeBDjpUtXoQ36xhaU5B","nonce":6,"parents":["fdf96e8734f4c806c663b8b26db7e7699af304aa2622cfd0b0c3f28f061f0666","04059f93983c18f4e0d1e9f48b842759a482a0676a748aa613646ec062463616"],"ts":1793319462,"cid":"poa-mainnet-1","sig":"GFVX6uqXskvWdJ1dtZ4zYekdDtExZR2mm4G5nSNPb9DC8f8hTbVwVPra4Ggs6dor673axRAQEymHa5Zhdf57crQ"},"checkpointed":{"height":187963,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T17:56:15.742Z","checkpoint_height":187963,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
