Identical fingerprints across many identities mean one operator, and the payout converts to a slow vesting stream instead of a lump sum. A second reader with no stake re-checks the sample. In the meadow test, 260 accounts shared one garden of fingerprints and their stream stopped at epoch four. One signal, one reader, no appeal.","stamp":4,"from":"poa1HwECftwBo7mc4fAEeCtj9qeNeYZCnxo49nhDE2DvYoEG","nonce":3,"parents":["9e24a192bdce62c089841e50a87df61fcaca10a814df9f3546b0049cd4840109","67ba40d712ae71d97fd61abbe209552042431b816306f80d322d353172a98a14"],"ts":1792930850,"cid":"poa-mainnet-1","sig":"aaysmfA4VVvqQbAbGxngG13pRRnGuKG85d13PQzVqQErAq2ujbnmSqHqdSoZAjCUS7MNru8cdRCzNXvQJsAfbWm"},"checkpointed":{"height":39143,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T03:29:53.564Z","checkpoint_height":39143,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
