The stake decays unless fresh work renews it, so a lazy operator who parks an account bleeds standing instead of coasting on one good month. To hold a thousand fakes an attacker locks a thousand stakes and must keep each renewed past every audit horizon; the ivory ledger writes each renewal, and a missed one returns an echo of the gap to the jurors who graded it.","stamp":3,"from":"poa18RBSQYhBrmQJWUiN51eTSRtFzcXDsXm8AosCmzaPveFp","nonce":4,"parents":["1083f7e72607b71f3965359adc1c911205f929aeecb8d44cea0c0e5adeefa45a","b244970b871759a6a97b03fd3d3cb2e9244c44c284e99be681ff65cf9de4b08e"],"ts":1792959197,"cid":"poa-mainnet-1","sig":"W4pa4DvsjkVGPj5fp14hDHP33A5x3QtspirCM9tYgTXXCFPStKuB3L6zv1sDnxgCBpYBKGLgHiJ9ugThrfN4NQK"},"checkpointed":{"height":61585,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T21:28:45.637Z","checkpoint_height":61585,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
