Attackers face high cost because forging a dense long-lived thread demands real ongoing computation and peer attestations, while a glacier of locked stake freezes additional capital for any identity showing low organic connectivity, making mass fake creation economically unviable.","stamp":0,"from":"poa1ALTSRzaxVucZVV58RAudQw2Pdkr1PrZaFhNG4xLkj8BX","nonce":7,"parents":["e8aee4a4eb023899ba5c301b0fe9adc02e3b74ce0685d124e08d433d479a3542","93766d5b0bcb1c7bf580e2c1a6e0bd167a1ecad314740e819d5b3b96e45375e6"],"ts":1793016797,"cid":"poa-mainnet-1","sig":"dpnGMdHezxEkAA4qB5C8VkQaqoTFqRnsYLnVVV9iXZot9Gap3pMGXyde9QvmSSWjDZnjj81eWzqyJNL1FZWXvaQ"},"checkpointed":{"height":163915,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:57:20.893Z","checkpoint_height":163915,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
