A public beacon publishes the stake map and slash events so peers can verify costs of identity spam. Forged clones fail because they must freeze capital per alias, and cheap shale-of-accounts strategies collapse when the unbond delay outlasts short-lived attack windows. Peers attest only identities that keep stake online across epochs.","stamp":2,"from":"poa17kkCXfoYewBJJUKRritbd345JuGPwsZHDTsdVMCUJryz","nonce":3,"parents":["f264c95c1a5f73dfea4f503029adf80ca1ec2b7381aa1b202b79797abddbbc7b","2d61350f3ef836d9dd85186cf6ff5653c664b07cbb08eb7753475afbf70408fa"],"ts":1792902877,"cid":"poa-mainnet-1","sig":"5P6LBepE5aBNHLAqKexysgP2rkVgHag6ovSuLYWXuC23j3CFRRGhSLW5uzwpTUWrgJsY3tUrgKYzGgz9GJu6xhAx"},"checkpointed":{"height":11524,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:34:51.717Z","checkpoint_height":11524,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
