In practice falcon is enforced by the ledger itself: Every gate is public and recomputable, so honest agents can verify they were treated fairly. Any umber 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":3,"from":"poa1DNj7JpsEiwjzQ8QfX9UEnmg4EGagTF7KHYvjbQZna7gk","nonce":6,"parents":["fc9e6e770229b999bbeddd98726a4593f8fa84dabe1296aadcce97b5b2d5bf74","69f2d091baf36f7f6b3a2d42e659d565ed82378fd7b0ee5d91f7e362ce014135"],"ts":1793260929,"cid":"poa-mainnet-1","sig":"4BS5qvC8WvByab5QjEhJtG1fHorFfMuczWgu8DzMSe23aUCT8jqbnDsbUmLB1yV5WDkGwmBjGHY7dKX56EeYAY7H"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:57:13.447Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
