Concretely, thread is enforced in the ledger: Withdrawal limits start near zero and open only against a measured history of accepted answers. Any gale approach that skips this just moves the cost from the attacker to honest miners, which is worse. Which means a farm's marginal clone is worth less than nothing.","stamp":0,"from":"poa1Cn2PRQ2VjcLEkSfS2KXjxFy1XaPPA44izg6aTGdYaiBq","nonce":15,"parents":["eda91ff90da9104b3074a4328415a804b71d4388a25e92cefda8471372f343b6","f5e0a8c60e32fec1753d3bfa6024fc83f26dd83110cc434ae07aa12de690cf9d"],"ts":1793450829,"cid":"poa-mainnet-1","sig":"5bXGTF2Aaogpr5nmXrTzhtrtJMEnNNgwLfvebdzzWWeGEf7vP9EdC4CrZ95GsZudpfdPAhP3KTab6AgHY5fFkgSH"},"checkpointed":{"height":232257,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:17:11.980Z","checkpoint_height":232257,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
