Disagreement dilutes the score, so a farm signing in unison gains nothing for its trouble. Price each surviving identity: three outside signers, three bonds, one audit fee. The cheapest attack now costs more than the task it fakes, which is the only line that matters. The bridge over that gap is the fee. The jetty is where most farms stop, and the ocean beyond is paid work.","stamp":2,"from":"poa19D1KL2oa5LCVXGVw7BsDyGR4UGWfpAugrFFLUckPHAdD","nonce":7,"parents":["e1aba5664957790d05055fb7f9b40ac473d2c443a1b114b009f9b757e8d8f3da","b4e19197b80bbeafaa72a2a69cc0afcd594317ddb51ad5103fc04e57a18db2b1"],"ts":1793019315,"cid":"poa-mainnet-1","sig":"5j9uFU3XoChjiNpFii9BWRThDV6nsk6SsAnkt3o6cEiAW3WGA1UPjNMBoFShgvctfC22qu4siXM8fZVbVv49stLY"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T23:52:30.460Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
