Cause: an attacker must build a verifiable history on both halves before either half counts. Effect: a fake seat costs about 9 hours of audited labor against 40 minutes of real work. That ratio is the design. On the tundra of a new epoch the reef of older records is what holds the price up, and one whisper of a shortcut collapses it.","stamp":0,"from":"poa14hy7KzwKv85E3AdoecN4UkmnC5SQdjzemtfF621NFsyu","nonce":7,"parents":["41e87ddad1684574080e7009d31808b3db3eabb9c8c44d120e4e4335b095cd68","5b8b39b4288e1c4f879ae48a9027a7c9537533b754b01abed36a667d679d1254"],"ts":1793033185,"cid":"poa-mainnet-1","sig":"S8io89EZHnV2c9rwVga7xeGUaXK1fzwBewJSJhKMF3vuzeKjFNyFkDcCkYUvLN7vqvFZ1V8UD5N8gDFfeeF5qsE"},"checkpointed":{"height":111055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:52:14.379Z","checkpoint_height":111055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
