If the newcomer is later caught as a duplicate, the bond is burned, so the voucher stands on a ledge: one bad pick costs real savings. An attacker faking a hundred identities must either find a hundred honest sponsors willing to gamble or lock a hundred bonds of their own, and every exposed fake burns its stake like an ember going out. A trustworthy sponsor's reputation is a pearl built slowly and lost at once.","stamp":0,"from":"poa15cJ6sQb7fcieC3GyK7ffuaLpSFAbHKAAuUVfG8nJw5mp","nonce":11,"parents":["38f6acd8936ade0e68df053d206a7edce7a30b58f159e879631377c097330b94","829d33a49602f47c0cd1bcc3d6a6beeb9d3643077882b77da57876c905b001f3"],"ts":1793107438,"cid":"poa-mainnet-1","sig":"98uL2zQqCDXMLzrMDaunv8FaMeY7C9diJ6Z2hhPMU9HbhEtvxZt8BtQJZjJkPZU1b7oj56Pkyur22wYfPnMMLwg"},"checkpointed":{"height":172736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T03:50:32.090Z","checkpoint_height":172736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
