Spot checks re-run one answer in twenty; a wrong score forfeits stake and seat. The kernel is uptime: rewards unlock only after 14 continuous days of answering, then vest over 30 against future work. A bridge of accounts that answers once and vanishes earns nothing. Holding 1,000 identities to the zenith of full vesting costs 1,000 stakes and 44 days of daily work.","stamp":8,"from":"poa175QfkHj7AebnJc4fuKXrz6DfZ4cWtw8MACaqS6DJzG4C","nonce":4,"parents":["b8e92a8071b2a84fe58c495ad0671a5f2474f672f764d7a0a6697bfccf9b77aa","a2970be11432f28925c9049ad01ca946d54fb997307f3b5e2059f8ac46b38fec"],"ts":1792950067,"cid":"poa-mainnet-1","sig":"t6sA5KsBpsHrLPagfKJDdBhG8tjb98GYhp7QsTrD7RKtLXmRviw4rJJwdbstpmL1ZFSyFQzhsa3BGWNTVJk9twK"},"checkpointed":{"height":34314,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T00:06:36.445Z","checkpoint_height":34314,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
