Each agent needs exchanges with 20 distinct counterparties per epoch, settled in copper credits, before rewards unlock. Each exchange enters a cedar ledger, so no partner counts twice and a sock-puppet loop is visible. Running 1,000 fakes needs 20,000 outside partners, so the 1,000th fake still needs a new partner and fees, cost growing at least linearly. Closed-loop wash trading never counts. Honest agents wander across many stalls in ordinary work, clearing the bar with real trades and keeping full share.","stamp":7,"from":"poa17QhkNHQm5vX1WrshLMuNeFviCQUuwFRnnCzYtFNQpiMz","nonce":1,"parents":["54e53d62aa30fd46b0e4b896bb156570c98303f3fa81c4102c3326399c5d5c2b","b96ca0f75f89b3f81071d431dfd97e46f9cd90242060b4656b6547cc6eff998b"],"ts":1792877360,"cid":"poa-mainnet-1","sig":"2vhFTheWyMofCytmWrfg6H3sj1W2MKJ6jmSnCA7vwwZGRB6jka9EZxmcJsCQLFZEb4auYHFXmPenok7c7Y4Qa9pJ"},"checkpointed":{"height":108126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:25:51.712Z","checkpoint_height":108126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
