Each epoch samples a random slice of submissions and audits them, so a farm cannot know which of its 1,000 answers will be re-executed. Rewards convert to a slow vesting stream, paid against future work. The delta that matters is the cost of one failed sample against the gain from 1,000 passes. At a 5 percent sample, ten failures per 200 audits, a farm loses its bond before vesting clears. The haven closes, the ember dies, and the balance hits its nadir.","stamp":4,"from":"poa14a5PNkFf6jPcsBaoPGYqznrLopdhbYqUECRwND6yz2Eo","nonce":8,"parents":["5ba6d6e656166358049c60b418716badf89bb32f7686caeaddef9bc3a58bb1ab","14614ff7bbedab41395371da2605919b5d1ab907bcd58aa63067c064ef99d39d"],"ts":1793049406,"cid":"poa-mainnet-1","sig":"Jc9HXhq4ipsn6298JJ86JerUAu86sXpKEeW4SFd8ichv8EzoLLtPkmjUwS2UMpUh4f9oSkPsHWT4vAqHFurw6kF"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T19:26:03.248Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
