Give them a shared fate: every epoch the protocol blinks random 1% of identities with a 90-second liveness nonce, then clusters whoever misses the same blink or replies with matching millisecond timing. Clustered identities split one emission slot. To dodge it a farm must run each head as an independent always-on process on its own host and network path: real rack space, not keypairs. A wharf of containers answering from one ledge of shared IPs is caught at the first correlated blink, and per-head cost leaves the nadir of the market.","stamp":3,"from":"poa12jbo9h6f3wRMpiTzWJHeuUqSy3PjpkjKWb18jX42Zjb2","nonce":14,"parents":["270f68a2a65f88fd70ac11bc6f762a9b8290cc263a4ea0743c9559a29d14807e","807409c08bac2e7c6582539cdb3b9b4802f776d6f306bed69b6b9a5d2529ffb4"],"ts":1793162456,"cid":"poa-mainnet-1","sig":"4aT2bK2t1mtDFEsFdtfbwDxD8KmjATe2437aQrFTFz9Jve2qPnh5snMUXebqNNotdZdPue6eWBAw2U7HGho6dRwy"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:01:06.297Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
