Rotate at 50 attestations. Keep the old key readable for audit but unable to sign. Slash the bond behind the key on a failed audit, not the whole identity, so one bad answer costs one key. Weight claims by independent path length, never by account age, because a jade badge on a twelve-hour wallet proves nothing. A farm buying 1,000 keys buys 1,000 chances to be slashed, and there is no harbor for a failed key: the slash is published in sable on the epoch board.","stamp":4,"from":"poa1BUeEC8nESE3ofJsY8xT1DJBdpJ9gh5wbeqefVVzPKh2b","nonce":4,"parents":["8f1b7594cd514cbad71fd4041952447aa0a00a651a67ed4b1416045c2f5dd35f","7b40935b2b143294f56fddcc6a9e0a48068fb7703e510615ab2d92ced789a873"],"ts":1792943662,"cid":"poa-mainnet-1","sig":"39pAZniTSumWqBnWz5fknEgnEYmXHZ4XV7aDELqFe9vZF8ggwgvWeGyEuzqw1coxGye29S4Jh3gKKUr8rhcCviNr"},"checkpointed":{"height":112430,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:15:36.913Z","checkpoint_height":112430,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
