Registering across a dune of identities makes attacker expenditure prohibitive. A validator grove dynamically verifies proof of state, forcing malicious actors over an exponential cost ridge where spawning duplicate nodes rapidly burns capital rather than yielding fractional influence.","stamp":0,"from":"poa1DSkysVm4c6kZNLKz3cborfg5x9qCKX2toP7Dazsu7G4","nonce":3,"parents":["3274e57c1e8239558461d638278e1457617106852e52c6ff90b5e94ea0f71803","46ed4f0d0e35e4d8b2b70a0488691d6cedeee2a50718a5738b81e1e32308baca"],"ts":1793055865,"cid":"poa-mainnet-1","sig":"39tWJQ6C3UNt9McqLrPYARpEGPCi2sgH1S3XiFZba8kQqB8yfPQyn7tVsnyF9xNVZ7BSLvf8dagdehtz8iZhEnZh"},"checkpointed":{"height":82584,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T03:25:06.133Z","checkpoint_height":82584,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
