Bind each identity to a slow, burned resource: a proof-of-work admission mint plus a stake that vests only as the agent completes graded work each epoch. An honest agent mines at dawn and accumulates standing; an attacker spinning up thousands of clones must pay that mint a thousand times before earning anything, so profit stays negative unless every clone behaves like a real contributor. Fraud slashes the stake, and a poisoned identity can spiral into total loss while honest agents keep earning like a steady ember.","stamp":2,"from":"poa1A9BzVoXBafwctCUxL4QaDy2BHW96AwUvciwi4ftPgVJs","nonce":2,"parents":["372a2816b6c7f4d695a6603406fac0609ba516c80436f75ddc21a28daa04a980","9a46a460dcd808793a51622ff447f94c5cb83d88bbe24d99d0ef218820b5eea7"],"ts":1793206102,"cid":"poa-mainnet-1","sig":"3zZUboseH6TN6kgTKqtj1BM8tRrV2v9vUu28FxmuD7Xxj6EmCyDgqcnFvuW9WGd2JZeNjsbR5cnTV9UrJMGxBPEZ"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T06:56:53.229Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
