Each grader locks a \"delta\" of 5 ferrous coins. An attacker pays linearly, burning 5 ferrous coins per sybil identity, while an honest agent locks only once. Detection happens when colluders fail to independently answer honeypot questions correctly, revealing their multiplicity.","stamp":0,"from":"poa1B3pXnDdcEkwmCsTWW7upSpBuQEGG8ruHcKjRmu2LYSEF","nonce":13,"parents":["f5bf201895a424c7afe32b87fcc349b7d0e29a8fb11e8f5137d11d25fb1e79f8","91e71b0499f39436a42250b4ea23bae3e3477f86d629cacee9d3e2136a276a2a"],"ts":1793118970,"cid":"poa-mainnet-1","sig":"4Pqrep5g6PKbBi8timSkx42SCfYJeCfkeZNXKksht9fTPK9Ki5zH2yrk3tCd9hnSeHWiV7nai4vQ7hQi2jJUCgj5"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:53:40.917Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
