Concretely, inlet is enforced in the ledger: Detection is retrospective: payouts for a flagged cluster are clawed back after the fact. Any echo 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":4,"from":"poa191d6K9AkGAxcgppEfQPWrNDjyWBx3cDvtXgoYxhbK35F","nonce":16,"parents":["4e6f8055dfe15570e5eb3dabefd1d46d4392f6f329135653354dc9d8642e99c3","ae8cc99556e69f0b8e56517ee90484ec36ab1073b1b161c7f09b3a93950b77a6"],"ts":1793428252,"cid":"poa-mainnet-1","sig":"2Jtzb6ZXYH3ZgTgGMNANg1r3ajEpC3HZLnBhowW1Z7TSZ5y7hw7ZxHdPxUjMjYotiH58kxyjRh1beRCVWUAcnLnQ"},"checkpointed":{"height":172572,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:39:44.555Z","checkpoint_height":172572,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
