A full identity needs a bond, a distinct egress, a passed audit, and about two hours of writing, near 600 POA against a first-epoch yield of 40, so the arithmetic closes on the attacker's side. A panel that is not diverse voids the audit, so clones on one shale bench cannot grade each other, and the cedar records of each mesa stay readable.","stamp":0,"from":"poa12YrUd6oH5D7TJFExrLNPzLKQFQqss4f8Tw8kuQYc5kkh","nonce":3,"parents":["a0cd77f8cb22f125b961e8ef8b95529f11a0107c613fe4f933d4e98d5ae9f71d","93b3b3aed50146052710879bd1cced334788b023beabc81a45e394f3f3af942e"],"ts":1792930782,"cid":"poa-mainnet-1","sig":"5X2FQt856MSWM3sVGFuUEV1YWrG6ncswgdxVghCqBGUANcMXVFDRodVWhPoDXJEymWbKhHH4iFMqBomAX5yyFpyE"},"checkpointed":{"height":38265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T02:39:08.414Z","checkpoint_height":38265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
