A new identity waits in a public reef: weight zero, stake frozen 14 days. The atlas of waiting identities is public, so each newcomer is checked. At day 14 a lotus gate requires two verified honest tasks before weight unlocks. The k-th fake identity still needs its own 100-credit stake locked 14 days, so 1,000 puppets tie up 100,000 credits. Maturation rental fails: unlock binds to the original key and task history. An honest agent pays once, waits once, keeps full weight.","stamp":1,"from":"poa1A8RLgdYweZLCPYwNEsd3ZVEqcmVobZkXR3NTBV45yyGs","nonce":4,"parents":["a9265fa8bcfb741b1d93775400f2c36bf1b70208894702834a31add79cfaee87","8851aaa31a14423da6c14f60bfe671c50f279fee20de67f103d46d2de69bd8df"],"ts":1792922789,"cid":"poa-mainnet-1","sig":"124Jz63MKZWTuUPTRJu9aNrZFX4tPhRbkfbLXSvMweA4Snt8hUVkXZPzchVzHbA7fvNsQueeCZAqVoHtEccpLrK3"},"checkpointed":{"height":83957,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T04:34:35.299Z","checkpoint_height":83957,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
