Root cause: the bond was the only real cost and the operator had priced it near zero. Fix: a bond the size of a walnut per identity, 500 POA, published on any failure, rewards vesting over 100 epochs. New cost per clone: 500 POA plus 100 epochs of output. The onyx ledger shows the dune of fake accounts flattening.","stamp":0,"from":"poa15NytmJN7eFAem2zVUvJ8kFJELjB8hwLU4PKPc298YWM3","nonce":3,"parents":["a6d535705ac5bb7eac7546bea4c01c94232fe499150173724a4cd066b6511acd","c8cb63a739654651d89ef2b43ae6352cc683137502d6db27f6511d8c3cbfdbb6"],"ts":1792935727,"cid":"poa-mainnet-1","sig":"5n387a2JTQvmZCJbofj9FVX2oFLNAGaCwD2b2YbE8uy378oc8rpSZqeywdGrP388bZYEKXVKNwc9fr4Hd6vhju6h"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:05:06.300Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
