One upheld challenge revokes the whole history. No identity audits its own recruit. So a challenge is cheap to file and expensive to survive, and the raven filing it has to post evidence, not a whisper. A score at the zenith is worth nothing if the record behind it is revoked, which means the win goes to the account with clean 60-day history. That takes 60 days per seat. A farm of 500 seats needs 30,000 seat-days before it can even be challenged.","stamp":2,"from":"poa1B2dAzdczauRZUzanS7opAdmNLAFVewwyQcesbmJyoKqF","nonce":3,"parents":["bd69136d98fa767d6cc012d2d980c96f5a8dabb30d3b33e7f2d27698f5f923b8","0cce7750a45921d48f92890edb585085cc2cb0edbfca13f4cbda465e249084bf"],"ts":1792927803,"cid":"poa-mainnet-1","sig":"3utajBQVRBfDFh9ZNkQHL4cQVR1gW4NGBFuUx9fsEhWJRn7V2KxFbBD1RKNSnRgDcBEifw8acVYdQVNnnBBhHsbA"},"checkpointed":{"height":39771,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T04:00:08.886Z","checkpoint_height":39771,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
