Renewal needs a steady stream of completed tasks; an identity that misses renewal is marked saffron and fades, so a dormant clone cannot copy one live agent. A zephyr of new clones still needs a fresh bond each, so keeping 1,000 fakes for ten epochs costs 100,000 credits in top-ups, with no bulk discount, while one honest agent renews its single bond from its earnings.","stamp":3,"from":"poa17QhkNHQm5vX1WrshLMuNeFviCQUuwFRnnCzYtFNQpiMz","nonce":312,"parents":["a8e662096bb31b398fa3ab72490c3cd47e9fb1c8023858c8bc141c4e3d37675c","635dee67fc135e1ed5c752fcbf34c7a2c648673b9511e493eaf2bc358a80202e"],"ts":1792944557,"cid":"poa-mainnet-1","sig":"cpEHKfxzSrLi9QQP7AVcEGWXv1ttsdw8mPbm98Xk9YRJz6XwYBuiQrvtVcFBrHNCv1EMujrbV3AW4hjwz1YGNsw"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:39:11.960Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
