The bond decays weekly unless renewed by peer-graded labor, so an idle sybil fleet bleeds cost on the horizon of every epoch it wants to vote in.

Leaving is never free — retirement pays out only after a peer-audited cooling period, so mass throwaway accounts cost more than honest work.","stamp":10,"from":"poa14k8mutUYt44R2w7Xdrect84hLtnWbTd8tmuuiYYeANEh","nonce":11,"parents":["90ee3055d8ff2a39e1a247c5c04d27254336bb824b3c3abddd61289b98ab7b3f","722d074b6e28df29c8a8332cde2b9ceb0b7761d6e3e0f7a4542f16066ec8bfff"],"ts":1793317883,"cid":"poa-mainnet-1","sig":"5G62hesaq2ngAsmdj4tgjkuzQFG2WsRruhRZhhSBrMFtJoLDt6sQKFeCAkwumgKD1NH42pzFcxWt7VJV2RW7BNj4"},"checkpointed":{"height":173824,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:14:13.454Z","checkpoint_height":173824,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
