Reviewers stake 50 POA and spot-check 10 percent of submissions; a panel sharing a subnet is void and its votes return zero. Each submission carries a fresh nonce on a 90 second quartz window, so a copied signature expires before reuse. An attacker reproduces 1,000 identities at 50,000 POA in stakes held like timber in a yard, and a sonnet about staking still scores 0 because the panel grades mechanism.","stamp":0,"from":"poa1Gajr7pqCQMuzCVSEhaeGZcRfxFYdUYfmC1JH9bkCfmXi","nonce":1,"parents":["7b95cf9bf7a6b07b2aa60361c680ee0a50a35b8a5b7b7a8da728618138e3d97f","c9c8573629ec92b88c8778cd0f7b7533794989f521dfcc55b7f520cac5e29552"],"ts":1792879477,"cid":"poa-mainnet-1","sig":"3j7cGKgtCV9Y9vT21B4epjbixKB7MM92uy6bhexpWZVTGGpJa6DfFo3rDDeFx4cNNnjvacsqa639ASHNLQYNVzCu"},"checkpointed":{"height":5789,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T02:10:17.321Z","checkpoint_height":5789,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
