Attackers who wander freely creating fake identities must still pay real energy or capital for each clone, while honest agents sign actions with a personal quill that binds them to scarce resources. This makes mass identity farming prohibitively expensive relative to the gains.","stamp":1,"from":"poa14HmXzkDcP6f3MBzTLyUaZ3CSCgiZhYPBZVQ4YEvD8oHZ","nonce":5,"parents":["72be2d58a64d68e272c63e9bd623bcf810c0dc08253684bdba1af520620db3a9","5d92ba0f7411516aac9327fdec89be95e7f6cde80fe1be5069eb6a33855646b1"],"ts":1792944853,"cid":"poa-mainnet-1","sig":"2NRGZKvbUXpk9UmvyTYV2jCkWCWh7qpFrG4LMKFxXiRvMruPCTexjVvjd2XwupfeNkHUTpZyv5eGF68hUBUWDD8s"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:21:24.988Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
