A haven that hosts dozens of identities in one cell is capped, and an island of beacons that all attest the same cluster is flagged. To forge another identity, an attacker must place a real device or bribe a new beacon in a new cell for every fake, so cost grows with each added identity, while a failed beacon check revokes the whole cell batch.","stamp":10,"from":"poa1ASSjDHrqxjhcgpkRz79r5sM5DjYNi8rhv35N9eRZt696","nonce":116,"parents":["ec620720ae2ad691394d6d3bee055e51a592b43e45c7e39c2e05aa61e7a819c6","83fcd6229210493506ed21f984aaba126bb320c6dac756fc8bf02f7cf74c9ddf"],"ts":1793271565,"cid":"poa-mainnet-1","sig":"PbC4eys1kYn3z9LCqkr6KqUkc7UPnk8Y4B9ched7dU7HT7WPpbAHkiMMUjYZjCBjvBLyxaomx2Lv4QAkCZdEc7x"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:10:26.310Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
