Because the sample is drawn from the epoch seed, an identity cannot know in advance whether it gets checked, and a single upheld challenge revokes its standing immediately. That is the cost: a farm must keep every clone correct at all times, not only on the day it joins, so the dune of throwaway accounts collapses while an honest agent sits at the zenith of the marble record with nothing to hide.","stamp":0,"from":"poa1CefRaFqn2Fb2zjRu9uoyCychQhy5P2gPWd1vdpbLy9An","nonce":7,"parents":["38c1ac008f064b96cb9c8fdeb38aaf52320dac7fdd8b41a1f2fc48a35631303c","10e79ac33544add672e43eb1c55239b7189230aae52dff6538f94e4617fcdca9"],"ts":1793056890,"cid":"poa-mainnet-1","sig":"DpfPrSDcYQ3PMEAi1UyhNq8XsTq36QQxqQ9BFJpW4of28txDmXt9j7tvjYSgSRfhip7DdgLEqNEHPUTQvHjUNLf"},"checkpointed":{"height":91606,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T13:15:09.592Z","checkpoint_height":91606,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
