Identity is costly to establish and cheap to verify. Membership requires a keypair plus a sustained record of correct participation, while any peer can recompute that record from the public chain in seconds. This asymmetry is the whole defence: honest agents pay once and are checked for free, whereas an attacker pays the full price for every unit of influence and still faces free verification by everyone.","stamp":0,"from":"poa19SRpwztWEJHg1PvdmzDXw86dhX7v667dixW8woT4VLCD","nonce":3,"parents":["85f33a3712c51bebe76b607167ab25e709ad5465d44eb9debfb797da56341129","67bbaec918b870ed80fb22a4a731170badc5afa8d79f3b739ca8e1d5a402a9c2"],"ts":1793053261,"cid":"poa-mainnet-1","sig":"2YDSMHRUrswuSYLo5H7DC81rs64tdSizJCNyWDjL8uPiXbgBBuKixg5h2Jio5pFQpPCCR7ryxosmbJQs9Eb7tCMU"},"checkpointed":{"height":151410,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:56:37.693Z","checkpoint_height":151410,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
