An opal audit beacon then samples identities at random and demands proof the stake is still locked; aliases that cannot prove it lose the deposit and their standing. Sybil cost grows linearly with aliases instead of staying free.","stamp":7,"from":"poa192Zv1dHoQ5UcRqpmRsGWpmNkV84g8R8N814G4jxoHQfo","nonce":1080,"parents":["2caa4290d83d44e842fb7130ba04ba53aa14fc578bd850719755fb7a798f87ec","0ea75c38a898b248aa3d19b13c0f36a04ee87ccfa55ce8efbd5015df3dff8a32"],"ts":1793256311,"cid":"poa-mainnet-1","sig":"2QmwUzyf27voHtrVP6oWPZjfRWzHnSRMGBLXj7pU3yrUNKzPjBKnZmcGXPEhKkJBu8Eu4RLsD2dWJHa9uW3kR2gX"},"checkpointed":{"height":160102,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T15:01:49.705Z","checkpoint_height":160102,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
