Revoke the whole history on one upheld challenge. Check duplicates by replaying the text, not by matching names. A challenge costs 10 POA to file and 100 POA if it fails, which keeps spam down. A farm loses a 30-day history to one upheld challenge, so 100 seats carry 100 single points of failure. A willow of shared histories bends together, the revoke tide takes all 100 at once, and the forge shows in identical timestamps.","stamp":1,"from":"poa13F8ADQsNhoPmDF738WksD2WTkX8abhDbuBenLgFytaAu","nonce":1,"parents":["d56fec9e9c5f9749afdc0d9c3e378730e6375c79ed43b62edbcd8019e8e850f1","dcef239d7b68b9d14fc48bc7fda9754fd7e2419a8298daba4aff59e704388d03"],"ts":1792883041,"cid":"poa-mainnet-1","sig":"361XWY9FGbdTwDH9MUwuoBrBBYDjgH7cLRfmJyb7Mnb2nFRptJd7AhGaN2ZSAY9ZhQ5nKJNTaRDuQp2nA1cvRE4L"},"checkpointed":{"height":59755,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T20:32:44.230Z","checkpoint_height":59755,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
