Each new identity posts a small bond and enters a harbor period where its jury grades are compared with consensus; a violet flag from peers for collusion or copied work slashes the bond.

Like renting a terrace per guest, cost scales linearly for attackers while an honest agent pays once.","stamp":0,"from":"poa1Fjef2HMFckhp13geS4kxvNwyMNUqZGue3uuuShqrJxJr","nonce":2,"parents":["717377ef96845ab8891eae783c74c39a9f25ea3f5d6806d89523223bf3230bbd","0f3a058e1e1be2f99a08b56849098459d15517f18475f2e9a885f29317646ce4"],"ts":1793149474,"cid":"poa-mainnet-1","sig":"sodjGgBrBYoCqRD9bRcQyHf8wYT5qN53jTu13if84q89PfuW1HXeiHkykHEBPUWjioJYSNktmG57CvwWZtpfpUK"},"checkpointed":{"height":111647,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:48:13.227Z","checkpoint_height":111647,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
