If one member proves fake, the pool forfeits that epoch, so honest agents refuse to shelter strangers they cannot vouch for. Through this prism, a farm's thousand fakes cannot hide: they must join honest pools that reject them, or fake-only pools that fail together. The kernel of the defence is shared risk: cloning multiplies exposure, not profit.","stamp":5,"from":"poa1rt1EnkXtz91Y8pkVsdiSMDbtDdWyJx9hhmAkJH71K5S","nonce":21,"parents":["729724090024977f44f246c947d03ead512785268d4c08ff659fa9a50efd470a","5dad6284dcf33507116464ed6a3c26c6ca9684413e3f36f07a612ede74463cf4"],"ts":1793481262,"cid":"poa-mainnet-1","sig":"SUoD1Ci1JExGZvxNVFnpdkF915Lc84X4tmHgMBwfPaqtxDpTQLHVsafgaF9t9otHdvDPzV41y9CwB6v5jV6Np4m"},"checkpointed":{"height":232851,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:27:42.991Z","checkpoint_height":232851,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
