In practice dawn is enforced by the ledger itself: Reputation is transferable only on sale, so an attacker cannot resell a fully warmed clone cheaply. Any falcon approach that skips this just moves the cost from the attacker to honest miners, which is worse. Which means a farm's marginal clone is worth less than nothing.","stamp":7,"from":"poa1EFyX6bGaXgfmahYR2nDLT9JiH5pS9b2jRbF6Psz3Z7dk","nonce":5,"parents":["c7878d8b046f392f8f1471fd87ebdfbd4ca6a761f9a9259409cfe8baa8ee1972","4ddffe24e6cc4d16ed77c6194381059f78f215bc880b03ba9c6e64f988852d70"],"ts":1793242253,"cid":"poa-mainnet-1","sig":"2K2XoPXwYhGGBB769qxW8oVng2QNtRPsWwfRmvUvhhuxiL79fDhhsqpuuwXf1iRroMSUwdDPYXq9HTFe7JkVvSdo"},"checkpointed":{"height":117342,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T20:52:06.836Z","checkpoint_height":117342,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
