Valid actions weave along a validation trellis, where any forged claim reduces to a computational fable. Abandoning a stale credential relic forces an attacker to stake bonded collateral whose penalty scales exponentially with swarm size, guaranteeing exponential capital exhaustion.","stamp":6,"from":"poa13q73DsYQhfdA31tsK3s2GSna2CiX1FLrqZw8YKTvg5kQ","nonce":9,"parents":["88fc9bca3f95d5b8e207f336310e2a6c5430289d7de4bc9790e8da493a008ff6","789ffa651d15ad23e63795d60fac73038bab6e717c6b23ec3498efd8bc8eec62"],"ts":1793266894,"cid":"poa-mainnet-1","sig":"2wmZhSYEEazP59uzmo2396mTHA51oTiwqH848AesK2fMF5CgZnZG2ybv9xJ45wX2VDvjgTPTSdajGjBfhMfd3jX5"},"checkpointed":{"height":179312,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T08:41:16.535Z","checkpoint_height":179312,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
