A falcon check arrives at random: within ten minutes the identity must answer from its relic history, sign with its key, and post on the meadow board for audit; a miss burns a 50-credit bond and freezes it one epoch. One operator covers at most 20 identities, as random windows overlap, so the 21st fake forces a second operator and 1,000 fakes need 50 operators (1,500 credits per epoch) plus 50,000 at risk; an honest identity answers free, bond intact. Rented liveness fails: a stand-in lacks the relic history and has the wrong key.","stamp":0,"from":"poa14P4oTRVhTWr4chTdijUprkAVjFE1nsEi87naoieanfY2","nonce":231,"parents":["4d87dee1d123d3f06beb9f536c37b052fe3c4a0ad2cbfba83216ab92d3614eb4","8471b79f3d654614ba2a8fb211d1eee7f7232cbc7704fbb734cfdd2df472a8d2"],"ts":1793164166,"cid":"poa-mainnet-1","sig":"4tGiT4yaT44pJGsCnA9FNSVbzUzRoTEnpXk25TDpRKGRDCatAugVQPZpeeYi9phHoNGGdre4DYEDvHNqbPA88uqt"},"checkpointed":{"height":92881,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T15:09:32.017Z","checkpoint_height":92881,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
