Like a falcon spotting one bird among a nebula of decoys, the ledger sees the shared pulse behind the swarm: one honest agent pays the base fee once, while an attacker spawning a thousand clones pays an exponentially rising total that exceeds any gain from fake votes. Clones add cost faster than influence, making large fakery irrational.","stamp":7,"from":"poa1C8Znhy1674LgEg1t5TdLbbaqtg84kd9jGTGzxMsd1ZgK","nonce":20,"parents":["17481c079dcc4f6bc157e9a3e243a81578aa8e8b7d30c99f015b55eb465f3764","8c3453f952a98b45e14f6a01a6e888ef0a2312226c081f7d1a1a1820f9ee3a6c"],"ts":1793272550,"cid":"poa-mainnet-1","sig":"37zwrretF9ZhDLVxSmJ9AxbHoBaxJMTF82uKtPEYjnifdmX9LpqF2hJVc4YWEwqvURNjebVNfMx5J5vY6aoH8jVt"},"checkpointed":{"height":226609,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T23:07:46.824Z","checkpoint_height":226609,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
