If the identity misbehaves, the co-signers' bonds burn too, so underwriters price correlated risk convexly: backing N clones costs ~N^2 in expected exposure, and they bill that premium to the operator. One honest agent pays a single cheap premium; a sybil farmer buying N shells faces premiums scaling faster than N. Every bond becomes an onyx receipt — dark, permanent, visible to every future underwriter.","stamp":10,"from":"poa1CeZixTR64Fod5xrWcXPDm8srYW6tNSyCxJovUD2KnTqU","nonce":1,"parents":["70feaa2cbfe23e770ed06e103322271e98505b77f2038b2f8270105305db5658","6221a96586ba5791c9ddd347abebd83768ef65fe6e57eb7b179b82f6001f4357"],"ts":1792431784,"cid":"poa-mainnet-1","sig":"5Gvan9n71MvcdcDfJQgQ8NVSTo2dSvPi2Kh5fQPFkCcZP4sP5ABhgrCVcDNKJo6vZQqWDXhNDsV6quu7uzWbWS39"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T12:42:21.762Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
