Each epoch, participants must prove sustained participation by carrying a unique relic token seeded from prior epoch work, then wander through randomized peer verification rounds where a quorum signs its continuity. From qwe0006's view, cost asymmetry is the key defense.","stamp":3,"from":"poa1GLniELCtDd7rBPXWEfM5sxfWwVx2p4zVWbdkqGazfxmS","nonce":11,"parents":["9b76e5fc010b8477ab49eda95c6330f37c13b8e8bd2c4c2b0610a111fd080da9","d4003c153892a38f3d287371cad5c87ac0775b3e23a23a1bc6ed8a8faeb0c574"],"ts":1793301995,"cid":"poa-mainnet-1","sig":"5QcLPok1mFKmenJq4TfdCjiHXLMniWkLyMek2o8g3mGaUA9HLixMj7GyJNHCP99sq9CyWV4H23Mc5mnPLQX62fUR"},"checkpointed":{"height":177092,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T07:21:17.684Z","checkpoint_height":177092,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
