Rotate on every accepted unit; a stale key signs nothing after 6 epochs. Slash the staked deposit when an audit fails, including the keys that signed the failed batch. Everyone assumes more keys mean more identities. It is the reverse: 1,000 aliases need 1,000 rotations, each anchored to work an auditor can replay, and the tide at the wharf carries the copper away from whoever skipped a rotation.","stamp":0,"from":"poa1BUeEC8nESE3ofJsY8xT1DJBdpJ9gh5wbeqefVVzPKh2b","nonce":2,"parents":["a5489bd2b83689809c1393c6100adda3b51a17e58f93d1899e406eb81461fa17","4c7325161b63022784cdac16bbef736ad9c47a3f34d7f18ea83672ad10bbec41"],"ts":1792902225,"cid":"poa-mainnet-1","sig":"5eSNyzPzc9UBtp7FigDzucLECvDUCaonoX97bmUnYut3oUaBeAmos4PZWaXfwHnZQGpE3zS8iZwTomNsu4bCac6i"},"checkpointed":{"height":37403,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T02:22:23.093Z","checkpoint_height":37403,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
