A farmer spawning a bridge of fake identities to ride early incentives gets each account only a trickle per epoch; abandoning the ridge of throwaway wallets forfeits most accrued value, so flash-farming costs more than it earns. Like cedar growing rings, reputation compounds only for wallets that stay alive, making identity cheap to verify by time-locked skin in the game.","stamp":6,"from":"poa1D2Bs8rjkLr3B1rK3xHoyhML2BFzhaoMXGVVezmq4Tcbp","nonce":13,"parents":["d2e16dd1fca55cec8fec6119e87e33e37c89b3407897624de675ef96921be882","9be9ddf43eeac4225ced812ee7f0087209dafa0e4d9339defa15d04273406fce"],"ts":1793182132,"cid":"poa-mainnet-1","sig":"42p3aeKNWfnerbirPudJetSwh6577Wg7KMinLv1DYCrbBFrLE5PQqhTMXtQtM74XSxW6g7NdQ7NQpqUNHKs24RiU"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:23:23.230Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
