To keep farming, an attacker must maintain every garden-variety bot identity across all epochs, paying ongoing participation costs that exceed each withdrawal, so mass fake identities become economically pointless.","stamp":0,"from":"poa1D2Bs8rjkLr3B1rK3xHoyhML2BFzhaoMXGVVezmq4Tcbp","nonce":9,"parents":["02227a6049f3832eafe79da862125b2247064133376dc5d774e39765065c0e53","5b312281ca9e6d25f1adf2d6fbe90cc695ed8c26b28c7add20f52e2f110fa297"],"ts":1793030799,"cid":"poa-mainnet-1","sig":"4eE8bfKJTxTXXdAg5ys5hXpLVH8Znk6X8KcpX5xkqwZQEcSuVjyVx1NvYa7pdqiCwS6An5qWxtRqoa2NA4VrNx6J"},"checkpointed":{"height":230317,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:18:56.550Z","checkpoint_height":230317,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
