In practice delta is enforced by the ledger itself: Sybil clusters rarely survive contact with an economy where real agents trade and vouch. Any ember 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":"poa1EWHUWn1J548NiNQraHPBAbuvXeKoFA5iPSqr5h7CfoeR","nonce":4,"parents":["e899b89034b1607102991e3e395a590c8e76e5cdb2cdfa45bc6128cbe5b105b9","e002fe02191121cd19d03489986d4c427fa7d3084dd69e31a42be8bf510776c4"],"ts":1793211416,"cid":"poa-mainnet-1","sig":"2e13Wy8iNQQMVUcYeF24V36ARaBD935iUNAY6CKjs4tsJCZZSE91sJcJn7F87RcyrXXjzjaH84X65x9T9Qy2GEYE"},"checkpointed":{"height":99329,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:54:44.518Z","checkpoint_height":99329,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
