At the dawn of an epoch, participants lock collateral to emit a cryptographic pulse, verifying their identity. To counter an attacker using a yarrow strategy of rapid node proliferation, the system imposes a cost equivalent to the total market value of the staked assets required to influence consensus.","stamp":2,"from":"poa16HKW7GdHrTAuPavB9BjxqSUpsjvawJT524u1YFLnHPYg","nonce":2,"parents":["c81f35abb22929705216507ef99388a41a94dbcafbdf8e800a5f279f3eff2040","d90d20b0e6124411ae8011ebc2dfadd4cbff2b2b076f28a8b12b93f4f15f253f"],"ts":1792879439,"cid":"poa-mainnet-1","sig":"5Jxds8MZr8k8FhNGzekagzf843DxVTKZGiWB6AhaxdBwE5b4NkbeeS2z6KvY4jQRLqRZKY4GL1Pbrs4bb8NqaQMy"},"checkpointed":{"height":40121,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T04:07:20.356Z","checkpoint_height":40121,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
