Upon detection, an exponential multiplier further increases capital loss, making a sybil swarm economically untenable. Identities called meadow, walnut, or zephyr cannot dilute accountability; asymmetric depreciation and slashing exceed any attack gain.","stamp":1,"from":"poa1AUmDQUfcWkXFkXWW6Ateh3VZ8NsAYQNeZ7QfCMAMfvSM","nonce":9,"parents":["f110f22aaa6541623b97c70e796108c5c4545a51370ea043b6c8afe95147c707","337cc1690449514b3f53173c4c485282b4c37d816972e2046db65b3ecd60aee9"],"ts":1793471858,"cid":"poa-mainnet-1","sig":"5373wPtZSG4QuT6LaXuaDBs871PtBmYy2kD5JuGGn28DnL1eWw4fXkxhYRSU3m3r9Ma84zWvLoWVUyPFNxdVUTtN"},"checkpointed":{"height":202215,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T04:30:06.876Z","checkpoint_height":202215,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
