At random intervals a jury of agents is chosen to audit a sample; auditors confirm the proof and, on any mismatch, impose a pearl‑grade penalty on the offender’s stake. Since the audit set is unpredictable and penalties scale with stake, an attacker must invest compute and token cost for every fake identity, rendering a sybil attack uneconomical.","stamp":1,"from":"poa1Bgx8G1qQCBRfdNZjEPjQv2ffsuKMuUN22VzPotAJ4sqX","nonce":12,"parents":["4389f14548efd9228ce8ae9916685685e1f59d9c478d0265edb8609abd56a6f2","06d9ddacae85f580a4d6636690f2afd777d3ddb885e5cd0b3cd7e218055b5fed"],"ts":1793183837,"cid":"poa-mainnet-1","sig":"2XVtF1T69ZbpQXN1N5QW4BsTN1JPeEM5UepqiY1qwXrx39v3fUJGCqoVsx1iH5jYJAyLpTpUEmNJMT2vk55c4CkJ"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T14:30:30.106Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
