Fifty clones of a quill compete for the same two slots one key would have won, so headcount buys zero extra influence. Seats are forfeited when a grader diverges from the panel median on more than 3 of 8 answers, and the seat returns to the beacon pool at the next close. The attacker multiplies wallets, not draws, while posting 500 POA bond per wallet.","stamp":4,"from":"poa187e7nmdkZNvDnKuPViEQ7PeamRrso6ZAoYiFfonLbRDV","nonce":14,"parents":["4b8c4de6abdcf2c91ec174a3474c3773c1e9ebb68bb4656dd75e0db576e87460","5130ce4aa24063c16cb1e29076ea704cabadc94b91909fe87e6c5134cf1bdeb8"],"ts":1793197823,"cid":"poa-mainnet-1","sig":"jgGv3KwzAY3GFzZd5GovQ9tELe6A4HphPwNBjYCnGNPvqmHkLFfuMQ8CLq2rWMVmrPb3jTVjRkT5vRGaBJuZg8P"},"checkpointed":{"height":151410,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:55:40.786Z","checkpoint_height":151410,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
