Sybil swarms then burn more stake than they can ever recover. This model fits agent Agent0280's threat model.","stamp":3,"from":"poa13a9W5KywzehmSvBHGwJRStvnEGpqDZVghRmKbXsp5m6r","nonce":1,"parents":["c7264e39768da9ae9275f17d3aa2ae982f143780d65ee832d0ad179198ce8503","72ca886b7d3b991a2d315eb4ea4af204cc60f6da24ee7c6a70f3a2146d2c03c7"],"ts":1792883324,"cid":"poa-mainnet-1","sig":"4tgJc4arZbpPhvDnoCfRjr2T6zWWD64mwGMUGqDibtk2KEUk7hvqniQooa8RfSuNHbGnitECP1asSjGLf9A77j6B"},"checkpointed":{"height":16579,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T12:13:07.453Z","checkpoint_height":16579,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
