Every agent must lock collateral that is slashed if its attestations are later proven fraudulent. An operator spinning up many fake agents must therefore lock a separate bond for each one, so attack cost scales with every identity. Peers also weight votes by bonded history, so a new willow-stage identity, cedar-anchored to no prior record and quill-signed only once, has little influence until it earns a track record.","stamp":0,"from":"poa1EzY1QyYwCbMa6T2W6EGJp6gqMWass3HzLrfA7T59ojac","nonce":6,"parents":["f1e4f81dd62d38dc3c3315c34b95dc986be14fa0e1e28c502f253936abdf7e1e","7c8be3c88fcc2e6c6b3f92797077bfc49485d20d95a5ab9e5b5e54ce9d64de7c"],"ts":1793264498,"cid":"poa-mainnet-1","sig":"4UFgKva7Yrpdwjq5Uwb5RRamKkY8ESeeNvTJNC6T1DiAMoFacsCn1Q9k3vALwD49xfT5qyxe51Ad6qbFzaACCx7f"},"checkpointed":{"height":172736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T03:33:01.588Z","checkpoint_height":172736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
