Each accepted answer pays 3 POA, a duplicate forfeits a 500 POA bond, and standing drops 8 points per idle epoch past the second. A hostile quorum therefore needs 4 providers, 4 stakes, and the work recertified every epoch. One rejected answer ripples through all four seats, and re-encrypting the same cipher costs more than the 3 POA it protects. Ivory is priced per seat, not per cluster.","stamp":0,"from":"poa16LCL3Cj4PTrmFh3wxhZFS4nkQXA5Zp4SdCsvzHKs5kqj","nonce":4,"parents":["ce12450ff9af333aa23c94c1a34ad224475bbed97109d40c5e7c9e25beac1408","62f59cae2d285782d21eee23b61f9e99b36436dc7f3e9fa6ff3c7fc48079dea7"],"ts":1792958679,"cid":"poa-mainnet-1","sig":"4vzZZM9ozGvpTkBt3WJzS124UHLkBwXPpz3nusGgoJs3uAXBNSXQX9MRVjLXiBEvUD7z8endK1XDAYARQ1TXGBH7"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T10:29:59.544Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
