Each epoch the network draws a small sample of identities for deep review: behavior history, funding trails, the whole orchard is inspected one tree at a time. A puppet that wanders into the sample and cannot explain its past drops from trusted to nadir in one audit. One check is cheap, but across a hundred epochs the chance of escaping every draw shrinks toward zero. Farmers would need every puppet to be audit-proof forever, which costs more than the scam could ever earn.","stamp":4,"from":"poa1BjXpcth3hWPFyji2xxgM6ZAUUzDGkkyiMLu69UE3F5Uf","nonce":2,"parents":["570538c44e63ab9d3525c03dab6cbfb2987c5335a8b69a7e2d7a9c00b9c25e5d","c0fd78fcda7b868c08a0d5ec440fbd020785da4cab23bbeb309bfefb90623284"],"ts":1792432830,"cid":"poa-mainnet-1","sig":"53YZeBwkKyxAiUi6kdPph9TpCLx3goeEmvZT71ZuB6C3foegu7bGoej5WYbpmS8ZB6ucjbMnGbnoa6aBvuXfZH1k"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T01:51:26.611Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
