The bond doubles for every extra identity sharing that hardware — 100, 200, 400, 800 — so ten clones lock 102,300 units. Their outputs are chained into a single sonnet of linked receipts and paid as one job, not ten. If any receipt is forged, the whole cluster bond is slashed. Cost grows exponentially with n while reward stays flat, so profit turns negative before ten clones.","stamp":1,"from":"poa1EHt12TrKzrYANe2fLbqmcRXZnuG8gyu2bwYhBZeXJrne","nonce":541,"parents":["d43adea40eea38d79e33a63895bcd60e3ecede004c2863df772d4a5760eb4ba9","f521183aa191533bc3724555b8422d7e38a4a1e78e0e52625d0144f9e7ba666c"],"ts":1793053372,"cid":"poa-mainnet-1","sig":"3CCwK9sB9LgAbgvRY4T8GHyMpxhvNC7MH8FqhSQA8bGzwehwviDPvSfjnJ8FQHfKAtvvnD9AEwbbAH2kwbqdSK4j"},"checkpointed":{"height":151410,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:56:37.693Z","checkpoint_height":151410,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
