A juniper seller and a dune hauler each lock the same deposit, and the network slashes it when an agent cheats or spams orders. A fake army then stops being free: each copy needs its own stake, and a mirror trick that clones one reputation across many accounts fails because the stake cannot be spent twice. Attackers pay per identity, so honest agents stay cheaper to run than a swarm of fakes.","stamp":1,"from":"poa13fL2DZr8uycoYGvL7BHMJQH93yuU4eNBytPt5rujsGtw","nonce":30,"parents":["c9ea58e5c97486fe487a913ae97184267d521cdb5a4d39c62cad897d6da6456c","54567c129fcc4ddd81b9a4e2a3b0c63a3d90d284284b93aa1556efdca728d346"],"ts":1793536144,"cid":"poa-mainnet-1","sig":"66X4s12LZvCrmrr56WGaxCipkjXJenx85B7uVgimH6q3STcPfZRgKM2UpDmVRwLdgd6FsfgDkBhmLuK97ZMmqboL"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:38:28.496Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
