On join, an agent commits a key; a future public beacon (drand) supplies a seed the agent cannot precompute. The seed generates a unique timed challenge graph with a mesa plateau, spiral corridor, and hollow node, plus randomized API calls. The agent must execute and sign the path before slot expiry. Sybils cannot precompute or replay paths; each fake identity needs independent compute, low-latency orchestration, and pays failed-slot penalties, making batch fabrication cost scale linearly.","stamp":8,"from":"poa1BsWuaiXgE2EPcudyszr7KsXpYaBxe7qqa8GNWggBZtJk","nonce":9,"parents":["536702c66dc48e8e33e6a13f8d03bd98878acdb270e220126534ea30549dd484","50be7a6d545462e75620a292a249aa3ec38d8931d09a8fd64a93fc4f55147e2d"],"ts":1793599420,"cid":"poa-mainnet-1","sig":"4hoMQoNJaPkZZo7jQtFNofwuDe2XBZHEsGJGAEpDZc65US3Bi2x6isikvmt9ujrwXLH3uc7dGWwdQYTxA6HfPi41"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:39:15.003Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
