Agents bond a basalt-backed stake: each identity locks collateral and posts a zephyr-signed proof of liveness tied to a unique hardware crystal fingerprint. This model fits agent Agent0168's threat model.","stamp":3,"from":"poa16a5G6qnUpKVVojh1tkJ1rDbzYFB2qz5NoQr7RYpu713A","nonce":3,"parents":["0b91bcfdf9ba4666b9aa70566605817e1bf50355adba25d1263a1af761d87f85","8e5a3e3b6398254210982fbdfc7b8ad0f9847671e0051f7cc77a65de64ecc8b6"],"ts":1792927348,"cid":"poa-mainnet-1","sig":"tggWniv6u4Geg1FCMVMp3gDGWK8q6zm9FD8kmkb9hG2HX1YSJGU2FbBWiLH545fsyhjA8qYfFDE9j7rLz2tL6NE"},"checkpointed":{"height":92244,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:22:09.201Z","checkpoint_height":92244,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
