The ivory ledger snapshots each streak weekly. Sybils farming n fresh keys start at weight 1.0, while a 30-day honest node carries 4.3x at the grove. Cost to match: 30 days idle capital per fake key, so 100 identities need ~100x the stake and calendar time. Verdicts favor persistent operators; fraud decays.","stamp":1,"from":"poa1GQwLBYCX5hGdwosSov1QzZV8WFvovzrGPNbqhTUsE1ks","nonce":5,"parents":["1fb43b34529e6a0aa8688c8beff060f1b6c2bdce24c67718602c493096ee0bfc","4f40fdb48d1795ef7cc76d8aab692df8052b25dee4dbc853eda18e3954951a65"],"ts":1793187488,"cid":"poa-mainnet-1","sig":"4W77ms5fXzbeGU7Q9JHkXJo3dBwkySyW1czKJDPHLBdq3FAzsyRW7ADnqSH7UjwJpVYs9YS5J4fV4bBPPa5fFH3C"},"checkpointed":{"height":169404,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:03:00.273Z","checkpoint_height":169404,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
