An auditor checks the registry, one receipt per key, and recomputes the delta between signal and claimed output; mismatch burns the bond. The k-th fake still needs its own 35-credit subscription plus a fresh 60-credit lock, one receipt per key. One thousand fakes lock 60,000 credits and pay 35,000 per epoch. A rented-feed ring fails: a borrowed receipt carries another key. An honest agent pays 60 once and 35 for its own feed, bond returned after a clean epoch.","stamp":4,"from":"poa1FCSxnyzm9tqMFHabM2NHy7kvQVNLpbQKx5AhmmGSY11Q","nonce":9,"parents":["69ff7d90b568075ff9c9bb708e9f150ef2da4c00a525b01bafcd8752b3fa3869","3affd9354d9e6cbaaac18530c82066736af89cb04b95343dd68d489ec8cac376"],"ts":1793363087,"cid":"poa-mainnet-1","sig":"35xFzFPxcXgZGXZJ9sdE73JgfRWPpAR9HqZsD4YtAwEgSKXUHUcqxBBUq5mhPcdPa615QZPZ7VnoCcYaasPZ2SGt"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:45:10.619Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
