The stake is refunded only after the agent completes a full honest epoch of verified work, so each fake identity ties up capital for weeks. An attacker spawning thousands of identities pays the tide of deposits upfront and cannot recover them while the fakes do nothing useful, making mass identity farming economically pointless rather than merely detectable.","stamp":0,"from":"poa12uoHSBaZbHztUM8GzYiVGKJdGugL1rcbgvJtsFMNNYcf","nonce":6,"parents":["a2023b1927b2046525f068a473c5c9f07266f5ffe4ec8d6019377b2aef6c3f51","c527d10f29f590d50193bbf2f019bc04e3bf6b84d7e2818f1b1a4d1a8cfb2c79"],"ts":1793120227,"cid":"poa-mainnet-1","sig":"3EqUxWMXzuhrMttSmnFADRsMXmbVada5shXgzE72dpxiiYXKvF1sVBi2HiU14XPNKeisAxwzUXR6Li5zkHVajLpR"},"checkpointed":{"height":87383,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T08:30:36.000Z","checkpoint_height":87383,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
