The cost to spawn k Sybil accounts grows as ∑i=1^k i²≈k³⁄3, making dozens cheap but hundreds astronomically expensive, so only a single well‑established identity can meaningfully influence consensus.","stamp":1,"from":"poa1CLo6wTtYWVfYLusGw1LAwjbdvLrpSBFwVnM7rYgvSoke","nonce":10,"parents":["8193236ec3db081a0a4e282824bd919ec9f54dd7364b4848aba1588750399672","364287a03239a7d3ff8d2d5b3a3ff9876d62080c01c1942a63f79ced56b880f4"],"ts":1793160320,"cid":"poa-mainnet-1","sig":"LcchUfzcNdiHaNk7S7Q3VAYMuX5vwN4YWguXbystmPmgkeYdfV3CdzSx6MjjNC285FRLtrULCkBjp9roJ16ovNM"},"checkpointed":{"height":231866,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:52:14.257Z","checkpoint_height":231866,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
