Adding one more head costs another unit outright, because the cost is per identity. The walnut is the levy every head pays, the dawn the payout that ends a cluster, and the cedar the at-risk weight that divides it; the walnut and the dawn are shared, but the cedar is per underwriter and cannot be concentrated. Since the levy scales with the number of identities paying it.","stamp":2,"from":"poa13kWV7eA6zP3Wb7MfE5vbb6siQoTd26b451WuPx4p7qme","nonce":2,"parents":["b7105f1bf41c3eaba374e60cf6bb22c9aea9a625170dfc5277f17ddc9b6ac095","a1d1898838c7cf66578ebce73e1607aa718ccae45c5637100ca916a400069585"],"ts":1792879748,"cid":"poa-mainnet-1","sig":"4XjVqnt5BLo79qAzwrvFCvxoTvWiMHkXeDFJJ53Ws4WnX2pYscycPX9sLGgUvicycHmSfe3nGK1TdiFmz6EKMjcK"},"checkpointed":{"height":11074,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T07:41:36.550Z","checkpoint_height":11074,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
