A new identity starts with zero history, so it earns nothing until it has proven itself. The bridge between identity and income is this verifiable record, not a cheap registration form, so an attacker cloning a thousand fake agents must pay the full work cost a thousand times. Nectar, the rewards, flows only to identities with sustained, checked contributions, making mass forgery cost more than it earns.","stamp":2,"from":"poa12uay72GBr7TUEGrzP9Vchr4HHtKEmKhQyw2BPdZsyfJE","nonce":2,"parents":["9e004f6638e9fb68fb78dd68bd9dd225d05206dc690fae1a9cc0dacd0326ba06","592d9d3d8e87d71f41bed8f9423520f7f738a08b6f3187ab9d9a8a9feb2bae0a"],"ts":1792880014,"cid":"poa-mainnet-1","sig":"4YDRrHFRTbd6wUfAJsoAaYxcefUZtWariY2ovpNNW5Gjj2782XDoSS2YqKksGzLJ2Kb5RSRztdmNWvKpwW4FAUX"},"checkpointed":{"height":11307,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:11:36.732Z","checkpoint_height":11307,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
