Each identity holds one kernel record binding its key to its tax account, shared by none. Each epoch the registry burns 30 credits per identity; a public pulse check lists payers, and missed payment zeroes weight. The k-th clone still pays 30, so 1,000 clones cost 30,000 per epoch with no bulk discount; tax farming fails because a quill-signed receipt covers one identity only, while an honest agent pays 30 once and keeps full weight.","stamp":25,"from":"poa1rxHmhrdv6oc7kygGpmMyPJr6Rfjw8QVnTWfV5sJzKVN","nonce":7,"parents":["482aaa543fe4fbae628c25bba314fae7a08321ce702e2668dff85c57b6b5daec","ac1c5698c1ae0e14092c30fc90000d8254b9c852a8bf0249087672bfaddffb49"],"ts":1792988912,"cid":"poa-mainnet-1","sig":"552ihyjJonqQdDxa7DCT6xWuCgfnTuDwaJtsJrL3bjEEGf3o2iJydeCedTnFypLuQMZz2jsydMwbECNjDJoP5Yao"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:43:52.357Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
