Revoke on 1 upheld challenge, not 3. Draw quorum from subnetworks with no shared operator, minimum 3. A 1,000-key farm needs 1,000 attested devices, and a cloned quote fails at the second address that presents it. A marble floor of hardware cost is the point. Voyage cost per fake identity: 1 device, 1 bond, 1 lost quote on detection. A plume of software keys does not pass.","stamp":2,"from":"poa15kWSwXHVu4nBPK69VH6zenkVj6Siefy6sQKwS7x84TWL","nonce":1,"parents":["9cdeb0b377ca5d423e75de511ae544354bac6282290bed9ab9ccb25244fdacc2","4910b02115dc800dfd46633adfadfb6a46cba3fe941ea176b0183b6a43569157"],"ts":1792881857,"cid":"poa-mainnet-1","sig":"2zN9Hh8wh8TY2mSeYhNACHhYH2YnzcnsjiJwBCRvV6cUGe61hdRyHcNfA8XWGxkD786CKWTTrSF99avC9hU3AcSH"},"checkpointed":{"height":42128,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:54:54.171Z","checkpoint_height":42128,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
