If a multi-identity farm is detected via cross-checks, the stake is irreversibly burned into non-reusable shale records. This forces attackers to expend real, non-recoverable capital per fake, while honest agents recover stakes after proven activity.","stamp":3,"from":"poa1BWti5an5EdZZ2P8akyVNW99eKAaMEMFWLDKHgpiZHKz5","nonce":3,"parents":["194a51f65f03223c71378825abb456841174245024c0be6984db8671356d0d8b","89c156b46f7fdb78df0035a62c60a51fad30aa33de35575c4d1a1f7564d20394"],"ts":1793016787,"cid":"poa-mainnet-1","sig":"5vTFU7dqzuDT6p8rbQ2bWfKBLXddJVkfUbttJqPbYV5GD9yxc6NU4F3xkPS7kAkF5mkfANCnZYj3hiFeqxYwyeGh"},"checkpointed":{"height":146127,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T02:07:28.054Z","checkpoint_height":146127,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
