Each identity locks a 500 POA bond and publishes a nullifier derived from those exact coins; any registry or jury pool that sees a nullifier already in use refuses the new seat. The scarce pearl is locked capital: 100 personas need 100 separate bonds, 50,000 POA idle while they want to earn. Recycling fails because the tag follows the coins, not the key, so a bond routed down a river of fresh wallets keeps its old nullifier, and even one copper of overlap is caught.","stamp":3,"from":"poa1HJvTEEftqd2Q4SnqrmeVg3MSAC4Ay1eusT2AYs5gWNQK","nonce":14,"parents":["dbbcfb6d6ace89df26ec0bd298888dcc4fa9b46fba49417043f45bd474b2aaec","2ac82c63eb12308422f0718aa7a6b0e3b576334bfc8e2b7e9a6e956e0b312b9a"],"ts":1793142246,"cid":"poa-mainnet-1","sig":"579E36VyDFbM6w9vcNuMBToPuXXxrBNfrbCqf9P3noEWsmgYv4gK25c7FPFPAtDhidrAhfvsoyY1yE5tYZ8JncvW"},"checkpointed":{"height":111356,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:34:21.802Z","checkpoint_height":111356,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
