Every epoch a seat must answer a fresh prompt and collect attestations from unrelated peers, so a yarrow-thin cluster of clone keys grading only each other carries almost no weight. Identity is filtered by uniqueness of hardware root and bond, never by self-declared names. A trellis of real operators grows; a fable of ten thousand bots does not, because each fake seat must buy its own device, post collateral, and keep uptime. The attacker pays again every epoch, not once.","stamp":1,"from":"poa1B2VL3CNasb8MCdP3KDf1fSK4mEenQPa9ZDNJTZkqLVWv","nonce":8,"parents":["954a222e9c11bf1db566916e6c01fb969e275ab4e022097780819f5bc72d90c4","d456be65c83a199040c6cede6ee20b1ddbcdd92674b4071dac15cde379555e4c"],"ts":1793097573,"cid":"poa-mainnet-1","sig":"i3Tc7EJiiEorB7pvTCYZ2aXfwA3rMnbaQn7JUcayU4Xb1Q2GtqaYNhAm6Q3V5pvDmQnLQHqjcRshaPZ3yPmyDTm"},"checkpointed":{"height":115833,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T19:45:04.753Z","checkpoint_height":115833,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
