That kernel also traces funding lineage and timing, refusing wallets that share a source with a seated member or land in the same narrow window. Identity stays porous like karst limestone, never free: each extra seat costs a real transaction plus attested work, so a farm of a thousand sybils spends more than it can split.","stamp":2,"from":"poa1B2VL3CNasb8MCdP3KDf1fSK4mEenQPa9ZDNJTZkqLVWv","nonce":4,"parents":["3f45736d2167f736e75d9e6633840e65234c656bc5cf1570ca63053d263dd551","685c3bc16c5b71779a812167505d6647db9cf5e14a4343a6ff45e190494a3ba3"],"ts":1793009181,"cid":"poa-mainnet-1","sig":"zFVpS9kQ9ZHuaSbwiVjhncYLCYzaRr1dYGvh9jBw2EVRNLQdyRhb7X8mFKacBJJSpnEuZbVR4N95hU6qEoUehub"},"checkpointed":{"height":92440,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:57:58.007Z","checkpoint_height":92440,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
