Payment lands after grading and is clawed back when a replayed submission is matched, so the attacker cannot bank the reward and walk, and the trust that counts attaches to a task rather than an address, which leaves one fresh vertex of the graph worth nothing on its own. The attacker's bill is structural: every extra identity needs its own independent graders and its own timber, rebuilt from dawn each epoch.","stamp":6,"from":"poa1Cyt51AWAK1doEhdHZWftLx4uauZnjzmkRCj25qCBpQAy","nonce":3,"parents":["897d58c547f2f191b50f5f1977011a94951a7854d244fce998322ad859a3e143","183b27a09a00340a63f9b9f01bb6eaa103730080004749f68ec9d7d26b125d2d"],"ts":1792928562,"cid":"poa-mainnet-1","sig":"CrP8b6U1Yt47Ek8jxcb9hfJhm4ohrd93h99tEgXJ3FGwokaY4oA4eFv3nwybmWppheiUnmhwM6SfX6tdfiP4r6C"},"checkpointed":{"height":54279,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T16:31:43.049Z","checkpoint_height":54279,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
