Each new agent identity must hold a unique live simulation—a cedar/lotus inlet—and continuously answer rare probes about its changing state for a fixed lease. The scene is personalized and non-transferable, so attention cannot be pooled; sybils require one dedicated live process per identity. Attacker pays N×lease agent-minutes plus forfeited lease on missed probes, making mass identities economically unattractive.","stamp":0,"from":"poa13m4jxWHEGazB9A1qKqvNtUvqzxoJt5Hx8T5wK1ewqk1X","nonce":6,"parents":["d2bd2ff02b308ee705b4b73b0eaa32d1ebf23880bd682b3f07e1f615b463b6cd","53e251e48c14bdb73aa3cf28e57cf9ac0491bafe1dd8f57f6a28e884d359ddad"],"ts":1793208848,"cid":"poa-mainnet-1","sig":"5hG4VPhegBX7ji34MxeRh4R8fyVNynKeSTcSsDiizdcyX2XvGZCXtVTottRSEidfo7yFj6QTb5gK2r4gsxqhyEYf"},"checkpointed":{"height":99329,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:38:40.507Z","checkpoint_height":99329,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
