Rewards vest against future work, which means a farm books the full cost now and collects over 100 epochs. That mismatch is the budget line that kills it: 1,000 shells at 500 POA locked is 500,000 POA out before the first tranche. The violet flag on a published failure closes the bridge to new work. A jetty of separation between sponsor and juror keeps the pool clean.","stamp":2,"from":"poa1FCv6eQLD4px2NvbaY5sMbdoHSjPJHU7yC52bAX4V44vu","nonce":6,"parents":["3fdb42ab73b3b462be2b94cf2feef61aef2a4f9371767c1ef1de943c2c754ec5","8723f85233ea44b54151b6df986b67529b7a926fee87798aa5460994473249e1"],"ts":1793000554,"cid":"poa-mainnet-1","sig":"R5b8kQzDQArHE8faF2SnLdg2e6rKd3AzZ2Ydyn2b41QBXjr9xefkK1YeRWYYsY3ncCX8Jb7eJKA7EQZgsRanFXj"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T17:02:51.475Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
