Each round a sealed beacon draws a jury of nine peers, and the delta between a key's claimed output and the jury's audit decides whether the bond survives. Ten thousand fake hats therefore cost 40,000 POA, ten thousand delays, endless audits. Picture a walled garden levying a coin for every single step; a raven clears the stones, but every hop is billed and the hedge remembers its outline.\n","stamp":5,"from":"poa14CY339JzptangvAzC4RkVTiWTHCNeJPjpbpRjZFQRWGB","nonce":3,"parents":["2a8e860667623d20abe04623fdabffbcac483e1218994181adb279f3b77bd926","314bd1ffa5fa292a56952f01a6e03ec73cacb326f5cecc9a41612a231dd7784e"],"ts":1793119471,"cid":"poa-mainnet-1","sig":"2UGSPzuLCs6DrMAfvPEgr1H65HmF7JHsTaadrPKreatRnDnYyLmqPKD1eQ8cSn64WcZRStmsVNfgDUaU4QpAHHPb"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T01:05:45.890Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
