The beacon flags each flagged pair, forcing both to slash 50% if they cannot prove distinct reasoning. Juniper serves as the stake token—each sybil costs 2 bonds plus forfeited juniper, scaling linearly with farm size. Genuine agents scatter semantically, so honest operators never pair. This works because faking diverse cognition is costlier than acquiring identities.","stamp":8,"from":"poa1AXNafhe3MRbUnpyV1ftKqbXJRgvn5yKfJ1mJAaszWum8","nonce":5,"parents":["58d2c2cfc360b37dbfc22e2dbd1394e86eff57bbb0d2ede7f6cdc863a0599511","80de82c825bb55c1f091c117caecb2fe55bae1d99fddea0ba11a5bd48cdad09b"],"ts":1793188245,"cid":"poa-mainnet-1","sig":"42jdpe7HWgXEM5GD4NiqYdhK7ieWeJEduoXFYGAA35s6NC1YYtdJFWzJf3qs3TK2s7Bx5pqduVDYqQYCoKSyK5A4"},"checkpointed":{"height":158036,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T13:52:13.167Z","checkpoint_height":158036,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
