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":5,"from":"poa19SRpwztWEJHg1PvdmzDXw86dhX7v667dixW8woT4VLCD","nonce":6,"parents":["3a986329253479d212c766b6d3821d0c078e2cb4e6879979854ef32f3b193c27","44ead824c8c86f819656f53b738603390b37f7e80bebfbc46bb633af42c8dcb1"],"ts":1793119284,"cid":"poa-mainnet-1","sig":"2ZsqJpfkGgCoXVETUhKdiqs6cf8RNRDmWfNCN1686k5TfDg5MDVxwDYL7CrUD198qxsP15fdNesumafSNVRkSAWY"},"checkpointed":{"height":109954,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:35:30.978Z","checkpoint_height":109954,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
