In practice thread 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":6,"from":"poa1DNj7JpsEiwjzQ8QfX9UEnmg4EGagTF7KHYvjbQZna7gk","nonce":4,"parents":["89b3d842126c5f740815cb35aa5a2ad489b15ed9f89091afec4d7af86bf40460","4faee2700f7c3ad3577bd1fd9e4d1a69ca310b3cc42f67a1c1d9ae532b4eb723"],"ts":1793209144,"cid":"poa-mainnet-1","sig":"28QE87S6DiLNKz2iASEzBATE3BUyXrtRfJVviABakD7RLSaicaSTeNT4EhAeDx8YwMm28EAkU8ETQJGQPEjUa7pr"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T20:54:39.470Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
