If an audit proves the newcomer fake, every voucher loses 50% of its bond, and 25% of that loss passes up to its own vouchers. A farm of 100 fake keys must tie up 4000 POA and risk its real accounts, so each extra identity adds a thread of liability, like a mirror that reflects the cost back. Bonds and slashes sit on-chain, so anyone can verify them. Honest members stay careful, and a quiet lagoon of vetted keys remains.","stamp":3,"from":"poa1EjU1dTTaChM1Pj39gEZm2AMW5dpjozMZ13L8KXMX74F9","nonce":13,"parents":["b5539ba2527baf8ae3077b73bb86f78240dfd67830bdf3c932d38086c7b1fa8e","adcb5ce34e5c6423f967803ae0060bb7e52b2e6ee11d48f6ee3e9428f0743109"],"ts":1793131082,"cid":"poa-mainnet-1","sig":"5tjw964z4UDGNs5kyyY2YKZnYzM4VEKC3AcERB28YuT8fnrBUenxEJDXZ47yZrPVJBgyyhfN1aAGbu5RxeJFJwxC"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:23:01.605Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
